Purpose of a Book Review

Note: This information is geared toward researchers in the arts and humanities. For a detailed guide on writing book reviews in the social sciences, please check the USC Libraries guide to  Writing and Organizing Research in the Social Sciences , authored by Dr. Robert Labaree.

When writing an academic book review, start with a bibliographic citation of the book you are reviewing [e.g., author, title, publication information, length]. Adhere to a particular citation style, such as Chicago, MLA, or APA.  Put your name at the very end of the book review text.

The basic purpose of a book review is to convey and evaluate the following:

a.     what the book is about;

b.     the expertise of the author(s);

c.     how well the book covers its topic(s) and whether it breaks new ground;

d.     the author’s viewpoint, methodology, or perspective;

e.     the appropriateness of the evidence to the topical scope of the book;

f.      the intended audience;

g.     the arrangement of the book (chapters, illustrations) and the quality of the scholarly apparatus, such as notes and bibliographies.

Point "c. how well the book covers its topics and whether it breaks new ground" requires your engagement with the book, and can be approached in a variety of ways. The question of whether the book breaks new ground does not necessarily refer to some radical or overarching notion of originality in the author’s argument. A lot of contemporary scholarship in the arts or humanities is not about completely reorienting the discipline, nor is it usually about arguing a thesis that has never been argued before. If an author does that, that's wonderful, and you, as a book reviewer, must look at the validity of the methods that contextualize the author's new argument.

It is more likely that the author of a scholarly book will look at the existing evidence with a finer eye for detail, and use that detail to amplify and add to existing scholarship. The author may present new evidence or a new "reading" of the existing evidence, in order to refine scholarship and to contribute to current debate. Or the author may approach existing scholarship, events, and prevailing ideas from a more nuanced perspective, thus re-framing the debate within the discipline.

The task of the book reviewer is to “tease out” the book’s themes, explain them in the review, and apply a well-argued judgment on the appropriateness of the book’s argument(s) to the existing scholarship in the field.

For example, you are reviewing a book on the history of the development of public libraries in nineteenth century America. The book includes a chapter on the role of patronage by affluent women in endowing public libraries in the mid-to-late-1800s. In this chapter, the author argues that the role of women was overlooked in previous scholarship because most of them were widows who made their financial bequests to libraries in the names of their husbands. The author argues that the history of public library patronage, and moreover, of cultural patronage, should be re-read and possibly re-framed given the evidence presented in this chapter. As a book reviewer you will be expected to evaluate this argument and the underlying scholarship.

There are two common types of academic book reviews: short summary reviews, which are descriptive, and essay-length critical reviews. Both types are described further down.

[Parenthetically, writing an academic/scholarly book review may present an opportunity to get published.]

Short summary book reviews

For a short, descriptive review, include at least the following elements:

a.     the bibliographic citation for the book;

b.     the purpose of the book;

c.     a summary of main theme(s) or key points;

d.     if there is space, a brief description of the book’s relationship to other books on the same topic or to pertinent scholarship in the field.

e.     note the author's affiliation and authority, as well as the physical content of the book, such as visual materials (photographs, illustrations, graphs) and the presence of scholarly apparatus (table of contents, index, bibliography, footnotes, endnotes, credit for visual materials);

f.     your name and affiliation.

Critical or essay-length book reviews

For a critical, essay-length book review consider including the following elements, depending on their relevance to your assignment:

b.     an opening statement that ought to peak the reader’s interest in the book under review

c.     a section that points to the author’s main intentions;

d.     a section that discusses the author’s ideas and the book’s thesis within a scholarly perspective. This should be a critical assessment of the book within the larger scholarly discourse;

e.     if you found errors in the book, point the major ones and explain their significance. Explain whether they detract from the thesis and the arguments made in the book;

f.     state the book's place within a strand of scholarship and summarize its importance to the discipline;

g.    include information about the author's affiliation and authority, as well as the physical content of the book, such as visual materials (photographs, illustrations, graphs) and the presence of scholarly apparatus (table of contents, index, bibliography, footnotes, endnotes, credit for visual materials);

h.     indicate the intended readership of the book and whether the author succeeds in engaging the audience on the appropriate level;

i.     your name and affiliation.

Good examples of essay-length reviews may be found in the scholarly journals included in the JSTOR collection, in the New York Review of Books , and similar types of publications, and in cultural publications like the New Yorker magazine.

Remember to keep track of your sources, regardless of the stage of your research. The USC Libraries have an excellent guide to  citation styles  and to  citation management software .

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed   Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

How to Write a Book Review- A Step-by-Step Guide

Check out these 5 straightforward steps for composing the best book review.

Step 1: Planning Your Book Review – The Art of Getting Started

You’ve decided to take the plunge and share your thoughts on a book that has captivated (or perhaps disappointed) you. Before you start book reviewing, let’s take a step back and plan your approach. Knowing how to write a book review that’s both informative and engaging is an art in itself.

Choosing Your Literature

First things first, pick the book you want to review. This might seem like a no-brainer, but selecting a book that genuinely interests you will make the review process more enjoyable and your insights more authentic.

Crafting the Master Plan

Next, create an  outline  that covers all the essential points you want to discuss in your review. This will serve as the roadmap for your writing journey.

The Devil is in the Details

As you read, note any information that stands out, whether it overwhelms, underwhelms, or simply intrigues you. Pay attention to:

• The characters and their development
• The plot and its intricacies
• Any themes, symbols, or motifs you find noteworthy

Remember to reserve a body paragraph for each point you want to discuss.

The Key Questions to Ponder

When planning your book review, consider the following questions:

• What’s the plot (if any)? Understanding the driving force behind the book will help you craft a more effective review.
• Is the plot interesting? Did the book hold your attention and keep you turning the pages?
• Are the writing techniques effective? Does the author’s style captivate you, making you want to read (or reread) the text?
• Are the characters or the information believable? Do the characters/plot/information feel real, and can you relate to them?
• Would you recommend the book to anyone? Consider if the book is worthy of being recommended, whether to impress someone or to support a point in a literature class.
• What could be improved? Always keep an eye out for areas that could be improved. Providing constructive criticism can enhance the quality of literature.

Step 2 – Crafting the Perfect Introduction to Write a Book Review

In this second step of “how to write a book review,” we’re focusing on the art of creating a powerful opening that will hook your audience and set the stage for your analysis.

Identify Your Book and Author

Begin by mentioning the book you’ve chosen, including its  title  and the author’s name. This informs your readers and establishes the subject of your review.

Ponder the Title

Next, discuss the mental images or emotions the book’s title evokes in your mind . This helps your readers understand your initial feelings and expectations before diving into the book.

Judge the Book by Its Cover (Just a Little)

Take a moment to talk about the book’s cover. Did it intrigue you? Did it hint at what to expect from the story or the author’s writing style? Sharing your thoughts on the cover can offer a unique perspective on how the book presents itself to potential readers.

Present Your Thesis

Now it’s time to introduce your thesis. This statement should be a concise and insightful summary of your opinion of the book. For example:

“Normal People” by Sally Rooney is a captivating portrayal of the complexities of human relationships, exploring themes of love, class, and self-discovery with exceptional depth and authenticity.

Ensure that your thesis is relevant to the points or quotes you plan to discuss throughout your review.

Incorporating these elements into your introduction will create a strong foundation for your book review. Your readers will be eager to learn more about your thoughts and insights on the book, setting the stage for a compelling and thought-provoking analysis.

How to Write a Book Review: Step 3 – Building Brilliant Body Paragraphs

You’ve planned your review and written an attention-grabbing introduction. Now it’s time for the main event: crafting the body paragraphs of your book review. In this step of “how to write a book review,” we’ll explore the art of constructing engaging and insightful body paragraphs that will keep your readers hooked.

Summarize Without Spoilers

Begin by summarizing a specific section of the book, not revealing any major plot twists or spoilers. Your goal is to give your readers a taste of the story without ruining surprises.

Support Your Viewpoint with Quotes

Next, choose three quotes from the book that support your viewpoint or opinion. These quotes should be relevant to the section you’re summarizing and help illustrate your thoughts on the book.

Analyze the Quotes

Write a summary of each quote in your own words, explaining how it made you feel or what it led you to think about the book or the author’s writing. This analysis should provide insight into your perspective and demonstrate your understanding of the text.

Structure Your Body Paragraphs

Dedicate one body paragraph to each quote, ensuring your writing is well-connected, coherent, and easy to understand.

For example:

• In  Jane Eyre , Charlotte Brontë writes, “I am no bird; and no net ensnares me.” This powerful statement highlights Jane’s fierce independence and refusal to be trapped by societal expectations.
• In  Normal People , Sally Rooney explores the complexities of love and friendship when she writes, “It was culture as class performance, literature fetishized for its ability to take educated people on false emotional journeys.” This quote reveals the author’s astute observations on the role of culture and class in shaping personal relationships.
• In  Wuthering Heights , Emily Brontë captures the tumultuous nature of love with the quote, “He’s more myself than I am. Whatever our souls are made of, his and mine are the same.” This poignant line emphasizes the deep, unbreakable bond between the story’s central characters.

By following these guidelines, you’ll create body paragraphs that are both captivating and insightful, enhancing your book review and providing your readers with a deeper understanding of the literary work. 

How to Write a Book Review: Step 4 – Crafting a Captivating Conclusion

You’ve navigated through planning, introductions, and body paragraphs with finesse. Now it’s time to wrap up your book review with a  conclusion that leaves a lasting impression . In this final step of “How to write a Book Review,” we’ll explore the art of writing a memorable and persuasive conclusion.

Summarize Your Analysis

Begin by summarizing the key points you’ve presented in the body paragraphs. This helps to remind your readers of the insights and arguments you’ve shared throughout your review.

Offer Your Final Conclusion

Next, provide a conclusion that reflects your overall feelings about the book. This is your chance to leave a lasting impression and persuade your readers to consider your perspective.

Address the Book’s Appeal

Now, answer the question: Is this book worth reading? Be clear about who would enjoy the book and who might not. Discuss the taste preferences and circumstances that make the book more appealing to some readers than others.

For example:  The Alchemist is a book that can enchant a young teen, but those who are already well-versed in classic literature might find it less engaging.

Be Subtle and Balanced

Avoid simply stating whether you “liked” or “disliked” the book. Instead, use nuanced language to convey your message. Highlight the pros and cons of reading the type of literature you’ve reviewed, offering a balanced perspective.

Bringing It All Together

By following these guidelines, you’ll craft a conclusion that leaves your readers with a clear understanding of your thoughts and opinions on the book. Your review will be a valuable resource for those considering whether to pick up the book, and your witty and insightful analysis will make your review a pleasure to read. So conquer the world of book reviews, one captivating conclusion at a time!

How to Write a Book Review: Step 5 – Rating the Book (Optional)

You’ve masterfully crafted your book review, from the introduction to the conclusion. But wait, there’s one more step you might consider before calling it a day: rating the book. In this optional step of “how to write a book review,” we’ll explore the benefits and methods of assigning a rating to the book you’ve reviewed.

Why Rate the Book?

Sometimes, when writing a professional book review, it may not be appropriate to state whether you liked or disliked the book. In such cases, assigning a rating can be an effective way to get your message across without explicitly sharing your personal opinion.

How to Rate the Book

There are various rating systems you can use to evaluate the book, such as:

• A star rating (e.g., 1 to 5 stars)
• A numerical score (e.g., 1 to 10)
• A letter grade (e.g., A+ to F)

Choose a rating system that best suits your style and the format of your review. Be consistent in your rating criteria, considering writing quality, character development, plot, and overall enjoyment.

Tips for Rating the Book

Here are some tips for rating the book effectively:

• Be honest: Your rating should reflect your true feelings about the book. Don’t inflate or deflate your rating based on external factors, such as the book’s popularity or the author’s reputation.
• Be fair: Consider the book’s merits and shortcomings when rating. Even if you didn’t enjoy the book, recognize its strengths and acknowledge them in your rating.
• Be clear: Explain the rationale behind your rating so your readers understand the factors that influenced your evaluation.

Wrapping Up

By including a rating in your book review, you provide your readers with additional insight into your thoughts on the book. While this step is optional, it can be a valuable tool for conveying your message subtly yet effectively. So, rate those books confidently, adding a touch of wit and wisdom to your book reviews.

Additional Tips on How to Write a Book Review: A Guide

In this segment, we’ll explore additional tips on how to write a book review. Get ready to captivate your readers and make your review a memorable one!

Hook ’em with an Intriguing Introduction

Keep your introduction precise and to the point. Readers have the attention span of a goldfish these days, so don’t let them swim away in boredom. Start with a bang and keep them hooked!

Embrace the World of Fiction

When learning how to write a book review, remember that reviewing fiction is often more engaging and effective. If your professor hasn’t assigned you a specific book, dive into the realm of fiction and select a novel that piques your interest.

Opinionated with Gusto

Don’t shy away from adding your own opinion to your review. A good book review always features the writer’s viewpoint and constructive criticism. After all, your readers want to know what  you  think!

Express Your Love (or Lack Thereof)

If you adored the book, let your readers know! Use phrases like “I’ll definitely return to this book again” to convey your enthusiasm. Conversely, be honest but respectful even if the book wasn’t your cup of tea.

Templates and Examples and Expert Help: Your Trusty Sidekicks

Feeling lost? You can always get help from formats, book review examples or online  college paper writing service  platforms. These trusty sidekicks will help you navigate the world of book reviews with ease. 

Be a Champion for New Writers and Literature

Remember to uplift new writers and pieces of literature. If you want to suggest improvements, do so kindly and constructively. There’s no need to be mean about anyone’s books – we’re all in this literary adventure together!

Criticize with Clarity, Not Cruelty

When adding criticism to your review, be clear but not mean. Remember, there’s a fine line between constructive criticism and cruelty. Tread lightly and keep your reader’s feelings in mind.

Avoid the Comparison Trap

Resist the urge to compare one writer’s book with another. Every book holds its worth, and comparing them will only confuse your reader. Stick to discussing the book at hand, and let it shine in its own light.

Top 7 Mistakes and How to Avoid Them

Writing a book review can be a delightful and rewarding experience, especially when you balance analysis, wit, and personal insights. However, some common mistakes can kill the brilliance of your review. 

In this section of “How to write a book review,” we’ll explore the top 7 blunders writers commit and how to steer clear of them, with a dash of  modernist literature  examples and tips for students writing book reviews as assignments.

Succumbing to the Lure of Plot Summaries

Mistake: Diving headfirst into a plot summary instead of dissecting the book’s themes, characters, and writing style.

Example: “The Bell Jar chronicles the life of a young woman who experiences a mental breakdown.”

How to Avoid: Delve into the book’s deeper aspects, such as its portrayal of mental health, societal expectations, and the author’s distinctive narrative voice. Offer thoughtful insights and reflections, making your review a treasure trove of analysis.

Unleashing the Spoiler Kraken

Mistake: Spilling major plot twists or the ending without providing a spoiler warning, effectively ruining the reading experience for potential readers.

Example: “In Metamorphosis, the protagonist’s transformation into a monstrous insect leads to…”

How to Avoid: Tread carefully when discussing significant plot developments, and consider using spoiler warnings. Focus on the impact of these plot points on the overall narrative, character growth, or thematic resonance.

Riding the Personal Bias Express

Mistake: Allowing personal bias to hijack the review without providing sufficient evidence or reasoning to support opinions.

Example: “I detest books about existential crises, so The Sun Also Rises was a snoozefest.”

How to Avoid: While personal opinions are valid, it’s crucial to back them up with specific examples from the book. Discuss aspects like writing style, character development, or pacing to support your evaluation and provide a more balanced perspective.

Wielding the Vague Language Saber

Mistake: Resorting to generic, vague language that fails to capture the nuances of the book and can come across as clichéd.

Example: “This book was mind-blowing. It’s a must-read for everyone.”

How to Avoid: Use precise and descriptive language to express your thoughts. Employ specific examples and quotations to highlight memorable scenes, the author’s unique writing style, or the impact of the book’s themes on readers.

Ignoring the Contextualization Compass

Mistake: Neglecting to provide context about the author, genre, or cultural relevance of the book, leaving readers without a proper frame of reference.

Example: “This book is dull and unoriginal.”

How to Avoid: Offer readers a broader understanding by discussing the author’s background, the genre conventions the book adheres to or subverts, and any societal or historical contexts that inform the narrative. This helps readers appreciate the book’s uniqueness and relevance.

Overindulging in Personal Preferences

Mistake: Letting personal preferences overshadow an objective assessment of the book’s merits.

Example: “I don’t like stream-of-consciousness writing, so this book is automatically bad.”

How to Avoid: Acknowledge personal preferences but strive to evaluate the book objectively. Focus on the book’s strengths and weaknesses, considering how well it achieves its goals within its genre or intended audience.

Forgetting the Target Audience Telescope

Mistake: Failing to mention the book’s target audience or who might enjoy it, leading to confusion for potential readers.

Article and book reviews.

Some assignments may ask you to write a review of a book or journal article. Sometimes, students think a book report and a book review are the same. However, there are significant differences.

A  book report  summarizes the contents of the book, but a  book review  is a critical analysis of the book that describes, summarizes, and critiques the ideas in the book. A review is a means of going beyond the literal content of a source and is a tool for connecting ideas from a variety of academic sources. A review provides an objective analysis of ideas, support for opinions, and a way to evaluate your own opinions.

Why are book reviews beneficial to write?

Some instructors like to assign book reviews to help students broaden their view of the subject matter and to give students practice in critically evaluating ideas in the subject area. Instructors often require that students follow existing review formats modeled in the journals in their disciplines. 

If you are asked to use such formats, remember that citations for books and journal articles differ from discipline to discipline. Find out which style guide is appropriate for the discipline in which you are writing. (Refer to the discussion of style manuals in chapter 5 of this guide for more information.)

Reviews let you relate to authors and agree or disagree with their ideas. A review allows you to examine your understanding of a subject area in light of the ideas presented in the reviewed book and interact with the author and his or her ideas. Also, a book review helps your instructor evaluate your understanding of the subject matter and your ability to think competently in your discipline.

Here are some questions to keep in mind when you are writing a book review:

What exactly is the subject of the book? What are the author’s credentials to write about this subject? Is the title suggestive? Does the preface contain information about the author’s purpose?

What is the author’s thesis? Is it clearly stated, or do you have to dig it out of the facts and opinions? Does the author present the ideas in a balanced way? What are the author’s biases?

What organizational approach does the author use? Does the chosen organization support the author’s thesis effectively?

What conclusion or conclusions does the author draw? Does the conclusion agree with the thesis or stated purposes? How does the conclusion differ from or agree with your course textbook or other books you have read?

How has this book helped you understand the subject you are studying in the course? Would you recommend the book to your reader?

As you write your review, ask yourself these questions:

Have I represented the author and the ideas presented in the book in a fair and balanced way?

Does the ethical tone of my review prompt the reader to trust my judgment? (You may want to review the discussion on writing arguments in this chapter.)

Does my review reflect the interests of my readers and fulfill my reasons for writing the review?

Have I demonstrated my understanding of the content of the article or book I’m reviewing? Have I clearly addressed the major issues in the subject area?

Have I clearly stated my own biases as a reviewer?

Have I clearly expressed my position about how much or how little the author has contributed to my understanding of the subject in question? Have I recommended or not recommended the book to other prospective readers?

Have I checked my review for organizational, grammatical, and mechanical errors?

Key Takeaway

A book review or article review is a critical analysis of the material that describes, summarizes, and critiques the ideas presented. The purpose of a book or article review assignment is to broaden your knowledge base and understanding of a topic.

How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

What is a book review? 

A book review is the critical analysis of the book’s content and significance. It includes an evaluation of the plot, character development, and writing style. A good book review highlights the book’s strengths and weaknesses. Reviewers often include quotes to support the opinions mentioned in the book review. A book review is different from a book report which objectively describes the book’s main content. 

Now that we know what is a book review, let’s understand their length. 

How long is a book review? 

The length of a book review can vary, depending on the purpose and the medium used. Book reviews in newspapers, magazines, and journals can range from 500-2000 words. In contrast, book reviews by readers on platforms like Goodreads, Amazon, Facebook, or Google can range from 50-500 words. 

Now let us see the 6 easy steps to write book reviews. Whether you’re writing book reviews for your assignment or book promotion, these steps will help! 

How to write a book review

• Note down the key points- This is an important step before writing a book review. Jot down your analysis about the characters, themes, plot, and your personal view. Also, note down the book title, author’s name, and any relevant information about the book. 
• Start with a strong introduction- Mention the author’s name, book title, themes, and main characters in the introduction. The introduction should give a very brief book summary without giving spoilers. 
• Analyze the book- Discuss the book’s strong points and weaknesses. This can include your opinion on the narrative pacing, writing style, character development , and structure. You can also compare it with books belonging to a similar genre. To enhance the review, you can also use relevant quotes to support your perspective. 
• Reflect on your experience- Describe how the book makes you feel. Did you find it engaging or was it slow-paced? Were you happy with the climax or did you expect more? 
• Conclude the review- Summarize the important points and end the review with a final evaluative statement about the book. This is where you can state whether you will recommend the book to readers or not. This is an important step in writing a book review. 
• Rate the book (Optional)- Depending on the platform requirements, you can rate the book out of 5 or 10. 

Now that we’ve seen how to write a book review, let’s see five amazing tips to create the perfect book review.

Top 5 tips to create an amazing book review 

Here are the top 5 tips to create the perfect book review: 

• Start with an attractive hook- Begin the review with an intriguing question or statement, capturing the book’s essence. For example, “In ‘The Enchanted Labyrinth’, every page takes you into a magical world of intrigue and wonder. 
• Discuss originality- Write what makes the book unique as compared to other books in the same genre. If the book highlights an unexplored theme or gives a unique take on a common theme, you can mention it in the book review. 
• Analyze worldbuilding- Review the fictional world created by the author (Its depth, complexity and detail). You can discuss how the setting of the story affected your experience as a reader. This is a good practice, especially while reviewing fantasy and science fiction novels. 
• Evaluate key themes- Discuss how the central themes of the story are seamlessly woven into the narrative. You can do this by highlighting how the characters’ relationships and choices reflect the themes. Describe how themes add depth to the story. 
• Edit and proofread- Once you’ve completed your book review, thoroughly check it. Correct any grammatical mistakes , spelling, and word choice errors. 

Book review examples

1. a thousand splendid suns by khaled hosseini .

“A Thousand Splendid Suns,” by Khaled Hosseini, is a profoundly moving story set against the backdrop of Afghan history. This novel tells the tale of two women, Mariam and Laila, whose lives become entwined in a harrowing journey of friendship, suffering, and redemption.

Mariam, an illegitimate child, suffers from stigma and rejection from an early age. Her tragic story evolves when she is forced into an abusive marriage with Rasheed, a brutish shoemaker. Laila, born generations later, is initially a symbol of the new Afghanistan – hopeful and educated. Their shared struggles against the backdrop of Afghanistan crumbling under Taliban rule form the novel’s heart.

Hosseini’s writing is evocative, capturing the stark realities in Afghanistan while also highlighting the profound resilience of his characters. The author masterfully portrays the emotional landscapes of Mariam and Laila, making them vividly relatable.

“A Thousand Splendid Suns” is more than a story of survival; it is a testament to the unyielding strength of human connection and endurance. This book is a must-read, not only for its storytelling brilliance but for its deep exploration of the often-unheard voices of Afghan women. It’s a heartbreaking, yet ultimately hopeful novel that stays with you long after the last page.

Now let’s see another example of a book review. 

2. A Man Called Ove by Fredrik Backman 

“A Man Called Ove ” by Fredrik Backman is a heartwarming novel that takes readers on an emotional journey of its titular character, Ove. At first glance, Ove appears to be nothing more than a grumpy old man. However, as the story unfolds, we discover that there is so much more to Ove than meets the eye.

The novel skillfully explores themes of loss, grief, and the human capacity for change. Ove’s journey is one of rediscovery and redemption, as he learns to open his heart to the people around him. Backman’s writing is both poignant and humorous, capturing the essence of human relationships and the power of community.

Ove is a character who is easy to relate to, with his quirks making him all the more endearing. As we delve into his past through flashbacks, we understand the events that shaped him. These glimpses provide depth and complexity to his character, making him incredibly three-dimensional.

The supporting characters are equally charming and well-developed. Parvaneh, the pregnant neighbor, and her family are a refreshing contrast to Ove’s gruff exterior. Their interactions with Ove are both heartwarming and hilarious, playing an important role in his transformation.

What makes “A Man Called Ove” truly exceptional is its ability to elicit a wide range of emotions from its readers. It can make you laugh out loud on one page and bring tears to your eyes on the next. The story is a testament to the importance of human connection.

In conclusion, “A Man Called Ove” is a beautifully written novel that explores the themes of love, friendship, and the capacity for change. Fredrik Backman’s storytelling is both touching and humorous, and his characters are unforgettable. For those who appreciate heartwarming stories that inspire the soul, this book is a must-read.”

17 book review examples to help you write the perfect review.

It’s an exciting time to be a book reviewer. Once confined to print newspapers and journals, reviews now dot many corridors of the Internet — forever helping others discover their next great read. That said, every book reviewer will face a familiar panic: how can you do justice to a great book in just a thousand words?

As you know, the best way to learn how to do something is by immersing yourself in it. Luckily, the Internet (i.e. Goodreads and other review sites , in particular) has made book reviews more accessible than ever — which means that there are a lot of book reviews examples out there for you to view!

In this post, we compiled 17 prototypical book review examples in multiple genres to help you figure out how to write the perfect review . If you want to jump straight to the examples, you can skip the next section. Otherwise, let’s first check out what makes up a good review.

Are you interested in becoming a book reviewer? We recommend you check out Reedsy Discovery , where you can earn money for writing reviews — and are guaranteed people will read your reviews! To register as a book reviewer, sign up here.

Pro-tip : But wait! How are you sure if you should become a book reviewer in the first place? If you're on the fence, or curious about your match with a book reviewing career, take our quick quiz:

Should you become a book reviewer?

Find out the answer. Takes 30 seconds!

What must a book review contain?

Like all works of art, no two book reviews will be identical. But fear not: there are a few guidelines for any aspiring book reviewer to follow. Most book reviews, for instance, are less than 1,500 words long, with the sweet spot hitting somewhere around the 1,000-word mark. (However, this may vary depending on the platform on which you’re writing, as we’ll see later.)

In addition, all reviews share some universal elements, as shown in our book review templates . These include:

• A review will offer a concise plot summary of the book. 
• A book review will offer an evaluation of the work. 
• A book review will offer a recommendation for the audience. 

If these are the basic ingredients that make up a book review, it’s the tone and style with which the book reviewer writes that brings the extra panache. This will differ from platform to platform, of course. A book review on Goodreads, for instance, will be much more informal and personal than a book review on Kirkus Reviews, as it is catering to a different audience. However, at the end of the day, the goal of all book reviews is to give the audience the tools to determine whether or not they’d like to read the book themselves.

Keeping that in mind, let’s proceed to some book review examples to put all of this in action.

How much of a book nerd are you, really?

Find out here, once and for all. Takes 30 seconds!

Book review examples for fiction books

Since story is king in the world of fiction, it probably won’t come as any surprise to learn that a book review for a novel will concentrate on how well the story was told .

That said, book reviews in all genres follow the same basic formula that we discussed earlier. In these examples, you’ll be able to see how book reviewers on different platforms expertly intertwine the plot summary and their personal opinions of the book to produce a clear, informative, and concise review.

Note: Some of the book review examples run very long. If a book review is truncated in this post, we’ve indicated by including a […] at the end, but you can always read the entire review if you click on the link provided.

Examples of literary fiction book reviews

Kirkus Reviews reviews Ralph Ellison’s The Invisible Man :

An extremely powerful story of a young Southern Negro, from his late high school days through three years of college to his life in Harlem.

His early training prepared him for a life of humility before white men, but through injustices- large and small, he came to realize that he was an "invisible man". People saw in him only a reflection of their preconceived ideas of what he was, denied his individuality, and ultimately did not see him at all. This theme, which has implications far beyond the obvious racial parallel, is skillfully handled. The incidents of the story are wholly absorbing. The boy's dismissal from college because of an innocent mistake, his shocked reaction to the anonymity of the North and to Harlem, his nightmare experiences on a one-day job in a paint factory and in the hospital, his lightning success as the Harlem leader of a communistic organization known as the Brotherhood, his involvement in black versus white and black versus black clashes and his disillusion and understanding of his invisibility- all climax naturally in scenes of violence and riot, followed by a retreat which is both literal and figurative. Parts of this experience may have been told before, but never with such freshness, intensity and power.

This is Ellison's first novel, but he has complete control of his story and his style. Watch it.

Lyndsey reviews George Orwell’s 1984 on Goodreads:

YOU. ARE. THE. DEAD. Oh my God. I got the chills so many times toward the end of this book. It completely blew my mind. It managed to surpass my high expectations AND be nothing at all like I expected. Or in Newspeak "Double Plus Good." Let me preface this with an apology. If I sound stunningly inarticulate at times in this review, I can't help it. My mind is completely fried.

This book is like the dystopian Lord of the Rings, with its richly developed culture and economics, not to mention a fully developed language called Newspeak, or rather more of the anti-language, whose purpose is to limit speech and understanding instead of to enhance and expand it. The world-building is so fully fleshed out and spine-tinglingly terrifying that it's almost as if George travelled to such a place, escaped from it, and then just wrote it all down.

I read Fahrenheit 451 over ten years ago in my early teens. At the time, I remember really wanting to read 1984, although I never managed to get my hands on it. I'm almost glad I didn't. Though I would not have admitted it at the time, it would have gone over my head. Or at the very least, I wouldn't have been able to appreciate it fully. […]

The New York Times reviews Lisa Halliday’s Asymmetry :

Three-quarters of the way through Lisa Halliday’s debut novel, “Asymmetry,” a British foreign correspondent named Alistair is spending Christmas on a compound outside of Baghdad. His fellow revelers include cameramen, defense contractors, United Nations employees and aid workers. Someone’s mother has FedExed a HoneyBaked ham from Maine; people are smoking by the swimming pool. It is 2003, just days after Saddam Hussein’s capture, and though the mood is optimistic, Alistair is worrying aloud about the ethics of his chosen profession, wondering if reporting on violence doesn’t indirectly abet violence and questioning why he’d rather be in a combat zone than reading a picture book to his son. But every time he returns to London, he begins to “spin out.” He can’t go home. “You observe what people do with their freedom — what they don’t do — and it’s impossible not to judge them for it,” he says.

The line, embedded unceremoniously in the middle of a page-long paragraph, doubles, like so many others in “Asymmetry,” as literary criticism. Halliday’s novel is so strange and startlingly smart that its mere existence seems like commentary on the state of fiction. One finishes “Asymmetry” for the first or second (or like this reader, third) time and is left wondering what other writers are not doing with their freedom — and, like Alistair, judging them for it.

Despite its title, “Asymmetry” comprises two seemingly unrelated sections of equal length, appended by a slim and quietly shocking coda. Halliday’s prose is clean and lean, almost reportorial in the style of W. G. Sebald, and like the murmurings of a shy person at a cocktail party, often comic only in single clauses. It’s a first novel that reads like the work of an author who has published many books over many years. […]

Emily W. Thompson reviews Michael Doane's The Crossing on Reedsy Discovery :

In Doane’s debut novel, a young man embarks on a journey of self-discovery with surprising results.

An unnamed protagonist (The Narrator) is dealing with heartbreak. His love, determined to see the world, sets out for Portland, Oregon. But he’s a small-town boy who hasn’t traveled much. So, the Narrator mourns her loss and hides from life, throwing himself into rehabbing an old motorcycle. Until one day, he takes a leap; he packs his bike and a few belongings and heads out to find the Girl.

Following in the footsteps of Jack Kerouac and William Least Heat-Moon, Doane offers a coming of age story about a man finding himself on the backroads of America. Doane’s a gifted writer with fluid prose and insightful observations, using The Narrator’s personal interactions to illuminate the diversity of the United States.

The Narrator initially sticks to the highways, trying to make it to the West Coast as quickly as possible. But a hitchhiker named Duke convinces him to get off the beaten path and enjoy the ride. “There’s not a place that’s like any other,” [39] Dukes contends, and The Narrator realizes he’s right. Suddenly, the trip is about the journey, not just the destination. The Narrator ditches his truck and traverses the deserts and mountains on his bike. He destroys his phone, cutting off ties with his past and living only in the moment.

As he crosses the country, The Narrator connects with several unique personalities whose experiences and views deeply impact his own. Duke, the complicated cowboy and drifter, who opens The Narrator’s eyes to a larger world. Zooey, the waitress in Colorado who opens his heart and reminds him that love can be found in this big world. And Rosie, The Narrator’s sweet landlady in Portland, who helps piece him back together both physically and emotionally.

This supporting cast of characters is excellent. Duke, in particular, is wonderfully nuanced and complicated. He’s a throwback to another time, a man without a cell phone who reads Sartre and sleeps under the stars. Yet he’s also a grifter with a “love ‘em and leave ‘em” attitude that harms those around him. It’s fascinating to watch The Narrator wrestle with Duke’s behavior, trying to determine which to model and which to discard.

Doane creates a relatable protagonist in The Narrator, whose personal growth doesn’t erase his faults. His willingness to hit the road with few resources is admirable, and he’s prescient enough to recognize the jealousy of those who cannot or will not take the leap. His encounters with new foods, places, and people broaden his horizons. Yet his immaturity and selfishness persist. He tells Rosie she’s been a good mother to him but chooses to ignore the continuing concern from his own parents as he effectively disappears from his old life.

Despite his flaws, it’s a pleasure to accompany The Narrator on his physical and emotional journey. The unexpected ending is a fitting denouement to an epic and memorable road trip.

The Book Smugglers review Anissa Gray’s The Care and Feeding of Ravenously Hungry Girls :

I am still dipping my toes into the literally fiction pool, finding what works for me and what doesn’t. Books like The Care and Feeding of Ravenously Hungry Girls by Anissa Gray are definitely my cup of tea.

Althea and Proctor Cochran had been pillars of their economically disadvantaged community for years – with their local restaurant/small market and their charity drives. Until they are found guilty of fraud for stealing and keeping most of the money they raised and sent to jail. Now disgraced, their entire family is suffering the consequences, specially their twin teenage daughters Baby Vi and Kim.  To complicate matters even more: Kim was actually the one to call the police on her parents after yet another fight with her mother. […]

Examples of children’s and YA fiction book reviews

The Book Hookup reviews Angie Thomas’ The Hate U Give :

♥ Quick Thoughts and Rating: 5 stars! I can’t imagine how challenging it would be to tackle the voice of a movement like Black Lives Matter, but I do know that Thomas did it with a finesse only a talented author like herself possibly could. With an unapologetically realistic delivery packed with emotion, The Hate U Give is a crucially important portrayal of the difficulties minorities face in our country every single day. I have no doubt that this book will be met with resistance by some (possibly many) and slapped with a “controversial” label, but if you’ve ever wondered what it was like to walk in a POC’s shoes, then I feel like this is an unflinchingly honest place to start.

In Angie Thomas’s debut novel, Starr Carter bursts on to the YA scene with both heart-wrecking and heartwarming sincerity. This author is definitely one to watch.

♥ Review: The hype around this book has been unquestionable and, admittedly, that made me both eager to get my hands on it and terrified to read it. I mean, what if I was to be the one person that didn’t love it as much as others? (That seems silly now because of how truly mesmerizing THUG was in the most heartbreakingly realistic way.) However, with the relevancy of its summary in regards to the unjust predicaments POC currently face in the US, I knew this one was a must-read, so I was ready to set my fears aside and dive in. That said, I had an altogether more personal, ulterior motive for wanting to read this book. […]

The New York Times reviews Melissa Albert’s The Hazel Wood :

Alice Crewe (a last name she’s chosen for herself) is a fairy tale legacy: the granddaughter of Althea Proserpine, author of a collection of dark-as-night fairy tales called “Tales From the Hinterland.” The book has a cult following, and though Alice has never met her grandmother, she’s learned a little about her through internet research. She hasn’t read the stories, because her mother, Ella Proserpine, forbids it.

Alice and Ella have moved from place to place in an attempt to avoid the “bad luck” that seems to follow them. Weird things have happened. As a child, Alice was kidnapped by a man who took her on a road trip to find her grandmother; he was stopped by the police before they did so. When at 17 she sees that man again, unchanged despite the years, Alice panics. Then Ella goes missing, and Alice turns to Ellery Finch, a schoolmate who’s an Althea Proserpine superfan, for help in tracking down her mother. Not only has Finch read every fairy tale in the collection, but handily, he remembers them, sharing them with Alice as they journey to the mysterious Hazel Wood, the estate of her now-dead grandmother, where they hope to find Ella.

“The Hazel Wood” starts out strange and gets stranger, in the best way possible. (The fairy stories Finch relays, which Albert includes as their own chapters, are as creepy and evocative as you’d hope.) Albert seamlessly combines contemporary realism with fantasy, blurring the edges in a way that highlights that place where stories and real life convene, where magic contains truth and the world as it appears is false, where just about anything can happen, particularly in the pages of a very good book. It’s a captivating debut. […]

James reviews Margaret Wise Brown’s Goodnight, Moon on Goodreads:

Goodnight Moon by Margaret Wise Brown is one of the books that followers of my blog voted as a must-read for our Children's Book August 2018 Readathon. Come check it out and join the next few weeks!

This picture book was such a delight. I hadn't remembered reading it when I was a child, but it might have been read to me... either way, it was like a whole new experience! It's always so difficult to convince a child to fall asleep at night. I don't have kids, but I do have a 5-month-old puppy who whines for 5 minutes every night when he goes in his cage/crate (hopefully he'll be fully housebroken soon so he can roam around when he wants). I can only imagine! I babysat a lot as a teenager and I have tons of younger cousins, nieces, and nephews, so I've been through it before, too. This was a believable experience, and it really helps show kids how to relax and just let go when it's time to sleep.

The bunny's are adorable. The rhymes are exquisite. I found it pretty fun, but possibly a little dated given many of those things aren't normal routines anymore. But the lessons to take from it are still powerful. Loved it! I want to sample some more books by this fine author and her illustrators.

Publishers Weekly reviews Elizabeth Lilly’s Geraldine :

This funny, thoroughly accomplished debut opens with two words: “I’m moving.” They’re spoken by the title character while she swoons across her family’s ottoman, and because Geraldine is a giraffe, her full-on melancholy mode is quite a spectacle. But while Geraldine may be a drama queen (even her mother says so), it won’t take readers long to warm up to her. The move takes Geraldine from Giraffe City, where everyone is like her, to a new school, where everyone else is human. Suddenly, the former extrovert becomes “That Giraffe Girl,” and all she wants to do is hide, which is pretty much impossible. “Even my voice tries to hide,” she says, in the book’s most poignant moment. “It’s gotten quiet and whispery.” Then she meets Cassie, who, though human, is also an outlier (“I’m that girl who wears glasses and likes MATH and always organizes her food”), and things begin to look up.

Lilly’s watercolor-and-ink drawings are as vividly comic and emotionally astute as her writing; just when readers think there are no more ways for Geraldine to contort her long neck, this highly promising talent comes up with something new.

Examples of genre fiction book reviews

Karlyn P reviews Nora Roberts’ Dark Witch , a paranormal romance novel , on Goodreads:

4 stars. Great world-building, weak romance, but still worth the read.

I hesitate to describe this book as a 'romance' novel simply because the book spent little time actually exploring the romance between Iona and Boyle. Sure, there IS a romance in this novel. Sprinkled throughout the book are a few scenes where Iona and Boyle meet, chat, wink at each, flirt some more, sleep together, have a misunderstanding, make up, and then profess their undying love. Very formulaic stuff, and all woven around the more important parts of this book.

The meat of this book is far more focused on the story of the Dark witch and her magically-gifted descendants living in Ireland. Despite being weak on the romance, I really enjoyed it. I think the book is probably better for it, because the romance itself was pretty lackluster stuff.

I absolutely plan to stick with this series as I enjoyed the world building, loved the Ireland setting, and was intrigued by all of the secondary characters. However, If you read Nora Roberts strictly for the romance scenes, this one might disappoint. But if you enjoy a solid background story with some dark magic and prophesies, you might enjoy it as much as I did.

I listened to this one on audio, and felt the narration was excellent.

Emily May reviews R.F. Kuang’s The Poppy Wars , an epic fantasy novel , on Goodreads:

“But I warn you, little warrior. The price of power is pain.”

Holy hell, what did I just read??

➽ A fantasy military school

➽ A rich world based on modern Chinese history

➽ Shamans and gods

➽ Detailed characterization leading to unforgettable characters

➽ Adorable, opium-smoking mentors

That's a basic list, but this book is all of that and SO MUCH MORE. I know 100% that The Poppy War will be one of my best reads of 2018.

Isn't it just so great when you find one of those books that completely drags you in, makes you fall in love with the characters, and demands that you sit on the edge of your seat for every horrific, nail-biting moment of it? This is one of those books for me. And I must issue a serious content warning: this book explores some very dark themes. Proceed with caution (or not at all) if you are particularly sensitive to scenes of war, drug use and addiction, genocide, racism, sexism, ableism, self-harm, torture, and rape (off-page but extremely horrific).

Because, despite the fairly innocuous first 200 pages, the title speaks the truth: this is a book about war. All of its horrors and atrocities. It is not sugar-coated, and it is often graphic. The "poppy" aspect refers to opium, which is a big part of this book. It is a fantasy, but the book draws inspiration from the Second Sino-Japanese War and the Rape of Nanking.

Crime Fiction Lover reviews Jessica Barry’s Freefall , a crime novel:

In some crime novels, the wrongdoing hits you between the eyes from page one. With others it’s a more subtle process, and that’s OK too. So where does Freefall fit into the sliding scale?

In truth, it’s not clear. This is a novel with a thrilling concept at its core. A woman survives plane crash, then runs for her life. However, it is the subtleties at play that will draw you in like a spider beckoning to an unwitting fly.

Like the heroine in Sharon Bolton’s Dead Woman Walking, Allison is lucky to be alive. She was the only passenger in a private plane, belonging to her fiancé, Ben, who was piloting the expensive aircraft, when it came down in woodlands in the Colorado Rockies. Ally is also the only survivor, but rather than sitting back and waiting for rescue, she is soon pulling together items that may help her survive a little longer – first aid kit, energy bars, warm clothes, trainers – before fleeing the scene. If you’re hearing the faint sound of alarm bells ringing, get used to it. There’s much, much more to learn about Ally before this tale is over.

Kirkus Reviews reviews Ernest Cline’s Ready Player One , a science-fiction novel :

Video-game players embrace the quest of a lifetime in a virtual world; screenwriter Cline’s first novel is old wine in new bottles.

The real world, in 2045, is the usual dystopian horror story. So who can blame Wade, our narrator, if he spends most of his time in a virtual world? The 18-year-old, orphaned at 11, has no friends in his vertical trailer park in Oklahoma City, while the OASIS has captivating bells and whistles, and it’s free. Its creator, the legendary billionaire James Halliday, left a curious will. He had devised an elaborate online game, a hunt for a hidden Easter egg. The finder would inherit his estate. Old-fashioned riddles lead to three keys and three gates. Wade, or rather his avatar Parzival, is the first gunter (egg-hunter) to win the Copper Key, first of three.

Halliday was obsessed with the pop culture of the 1980s, primarily the arcade games, so the novel is as much retro as futurist. Parzival’s great strength is that he has absorbed all Halliday’s obsessions; he knows by heart three essential movies, crossing the line from geek to freak. His most formidable competitors are the Sixers, contract gunters working for the evil conglomerate IOI, whose goal is to acquire the OASIS. Cline’s narrative is straightforward but loaded with exposition. It takes a while to reach a scene that crackles with excitement: the meeting between Parzival (now world famous as the lead contender) and Sorrento, the head of IOI. The latter tries to recruit Parzival; when he fails, he issues and executes a death threat. Wade’s trailer is demolished, his relatives killed; luckily Wade was not at home. Too bad this is the dramatic high point. Parzival threads his way between more ’80s games and movies to gain the other keys; it’s clever but not exciting. Even a romance with another avatar and the ultimate “epic throwdown” fail to stir the blood.

Too much puzzle-solving, not enough suspense.

Book review examples for non-fiction books

Nonfiction books are generally written to inform readers about a certain topic. As such, the focus of a nonfiction book review will be on the clarity and effectiveness of this communication . In carrying this out, a book review may analyze the author’s source materials and assess the thesis in order to determine whether or not the book meets expectations.

The Washington Post reviews David Grann’s Killers of the Flower Moon :

The arc of David Grann’s career reminds one of a software whiz-kid or a latest-thing talk-show host — certainly not an investigative reporter, even if he is one of the best in the business. The newly released movie of his first book, “The Lost City of Z,” is generating all kinds of Oscar talk, and now comes the release of his second book, “Killers of the Flower Moon: The Osage Murders and the Birth of the FBI,” the film rights to which have already been sold for $5 million in what one industry journal called the “biggest and wildest book rights auction in memory.”

Grann deserves the attention. He’s canny about the stories he chases, he’s willing to go anywhere to chase them, and he’s a maestro in his ability to parcel out information at just the right clip: a hint here, a shading of meaning there, a smartly paced buildup of multiple possibilities followed by an inevitable reversal of readerly expectations or, in some cases, by a thrilling and dislocating pull of the entire narrative rug.

All of these strengths are on display in “Killers of the Flower Moon.” Around the turn of the 20th century, oil was discovered underneath Osage lands in the Oklahoma Territory, lands that were soon to become part of the state of Oklahoma. Through foresight and legal maneuvering, the Osage found a way to permanently attach that oil to themselves and shield it from the prying hands of white interlopers; this mechanism was known as “headrights,” which forbade the outright sale of oil rights and granted each full member of the tribe — and, supposedly, no one else — a share in the proceeds from any lease arrangement. For a while, the fail-safes did their job, and the Osage got rich — diamond-ring and chauffeured-car and imported-French-fashion rich — following which quite a large group of white men started to work like devils to separate the Osage from their money. And soon enough, and predictably enough, this work involved murder. Here in Jazz Age America’s most isolated of locales, dozens or even hundreds of Osage in possession of great fortunes — and of the potential for even greater fortunes in the future — were dispatched by poison, by gunshot and by dynamite. […]

Stacked Books reviews Malcolm Gladwell’s Outliers :

I’ve heard a lot of great things about Malcolm Gladwell’s writing. Friends and co-workers tell me that his subjects are interesting and his writing style is easy to follow without talking down to the reader. I wasn’t disappointed with Outliers. In it, Gladwell tackles the subject of success – how people obtain it and what contributes to extraordinary success as opposed to everyday success.

The thesis – that our success depends much more on circumstances out of our control than any effort we put forth – isn’t exactly revolutionary. Most of us know it to be true. However, I don’t think I’m lying when I say that most of us also believe that we if we just try that much harder and develop our talent that much further, it will be enough to become wildly successful, despite bad or just mediocre beginnings. Not so, says Gladwell.

Most of the evidence Gladwell gives us is anecdotal, which is my favorite kind to read. I can’t really speak to how scientifically valid it is, but it sure makes for engrossing listening. For example, did you know that successful hockey players are almost all born in January, February, or March? Kids born during these months are older than the others kids when they start playing in the youth leagues, which means they’re already better at the game (because they’re bigger). Thus, they get more play time, which means their skill increases at a faster rate, and it compounds as time goes by. Within a few years, they’re much, much better than the kids born just a few months later in the year. Basically, these kids’ birthdates are a huge factor in their success as adults – and it’s nothing they can do anything about. If anyone could make hockey interesting to a Texan who only grudgingly admits the sport even exists, it’s Gladwell. […]

Quill and Quire reviews Rick Prashaw’s Soar, Adam, Soar :

Ten years ago, I read a book called Almost Perfect. The young-adult novel by Brian Katcher won some awards and was held up as a powerful, nuanced portrayal of a young trans person. But the reality did not live up to the book’s billing. Instead, it turned out to be a one-dimensional and highly fetishized portrait of a trans person’s life, one that was nevertheless repeatedly dubbed “realistic” and “affecting” by non-transgender readers possessing only a vague, mass-market understanding of trans experiences.

In the intervening decade, trans narratives have emerged further into the literary spotlight, but those authored by trans people ourselves – and by trans men in particular – have seemed to fall under the shadow of cisgender sensationalized imaginings. Two current Canadian releases – Soar, Adam, Soar and This One Looks Like a Boy – provide a pointed object lesson into why trans-authored work about transgender experiences remains critical.

To be fair, Soar, Adam, Soar isn’t just a story about a trans man. It’s also a story about epilepsy, the medical establishment, and coming of age as seen through a grieving father’s eyes. Adam, Prashaw’s trans son, died unexpectedly at age 22. Woven through the elder Prashaw’s narrative are excerpts from Adam’s social media posts, giving us glimpses into the young man’s interior life as he traverses his late teens and early 20s. […]

Book Geeks reviews Elizabeth Gilbert’s Eat, Pray, Love :

WRITING STYLE: 3.5/5

SUBJECT: 4/5

CANDIDNESS: 4.5/5

RELEVANCE: 3.5/5

ENTERTAINMENT QUOTIENT: 3.5/5

“Eat Pray Love” is so popular that it is almost impossible to not read it. Having felt ashamed many times on my not having read this book, I quietly ordered the book (before I saw the movie) from amazon.in and sat down to read it. I don’t remember what I expected it to be – maybe more like a chick lit thing but it turned out quite different. The book is a real story and is a short journal from the time when its writer went travelling to three different countries in pursuit of three different things – Italy (Pleasure), India (Spirituality), Bali (Balance) and this is what corresponds to the book’s name – EAT (in Italy), PRAY (in India) and LOVE (in Bali, Indonesia). These are also the three Is – ITALY, INDIA, INDONESIA.

Though she had everything a middle-aged American woman can aspire for – MONEY, CAREER, FRIENDS, HUSBAND; Elizabeth was not happy in her life, she wasn’t happy in her marriage. Having suffered a terrible divorce and terrible breakup soon after, Elizabeth was shattered. She didn’t know where to go and what to do – all she knew was that she wanted to run away. So she set out on a weird adventure – she will go to three countries in a year and see if she can find out what she was looking for in life. This book is about that life changing journey that she takes for one whole year. […]

Emily May reviews Michelle Obama’s Becoming on Goodreads:

Look, I'm not a happy crier. I might cry at songs about leaving and missing someone; I might cry at books where things don't work out; I might cry at movies where someone dies. I've just never really understood why people get all choked up over happy, inspirational things. But Michelle Obama's kindness and empathy changed that. This book had me in tears for all the right reasons.

This is not really a book about politics, though political experiences obviously do come into it. It's a shame that some will dismiss this book because of a difference in political opinion, when it is really about a woman's life. About growing up poor and black on the South Side of Chicago; about getting married and struggling to maintain that marriage; about motherhood; about being thrown into an amazing and terrifying position.

I hate words like "inspirational" because they've become so overdone and cheesy, but I just have to say it-- Michelle Obama is an inspiration. I had the privilege of seeing her speak at The Forum in Inglewood, and she is one of the warmest, funniest, smartest, down-to-earth people I have ever seen in this world.

And yes, I know we present what we want the world to see, but I truly do think it's genuine. I think she is someone who really cares about people - especially kids - and wants to give them better lives and opportunities.

She's obviously intelligent, but she also doesn't gussy up her words. She talks straight, with an openness and honesty rarely seen. She's been one of the most powerful women in the world, she's been a graduate of Princeton and Harvard Law School, she's had her own successful career, and yet she has remained throughout that same girl - Michelle Robinson - from a working class family in Chicago.

I don't think there's anyone who wouldn't benefit from reading this book.

A multiple book essay involves writing a review of two or generally no more than six books that cover the same overall subject area [e.g., analysis of European debt crisis] or that are related to each other in a particular way [e.g., applying grounded theory methods to study student access to education]. The reviews are written in the form of a short scholarly paper [essay] rather than as a descriptive review of the books. The purpose is to compare and contrast the works under review, identifying key themes and critical issues and assessing each writer's contributions to understanding the general topics discussed in each book. Professors assign reviews of multiple books to help students gain experience in evaluating the ways in which different researchers examine and interpret issues related to a specific research problem.

How to Approach Writing Your Review

Developing an Assessment Strategy

As with reviewing a work of collected essays, you must think critically about the research problem under study by multiple authors before you begin writing. The challenge is to develop an argument about each book you are reviewing and then clearly compare, contrast, and ultimately sythesize the themes into an well organized and well supported essay.

Think of a multiple book review essay as a type of compare and contrast paper similar to what you may have written for a general issue-oriented composition class . As you read through each book, write down the following questions and answer them as you read [remember to note the page numbers and from which book you got the information from so you can refer back it later!]. Which questions are most useful will depend upon the type of books you are reviewing and how they are related to each other.

Here are a series of questions to focus your thinking:

• What is the thesis—or main argument—of each book? If the author wanted you to get one idea from the book, what would it be? How does it compare or contrast to the world you know? What has the book accomplished?
• What exactly is the subject or topic of each book? Does the author cover the subject adequately? Does the author cover all aspects of the subject in a balanced fashion? Can you detect any biases? What is the approach to the subject (topical, analytical, chronological, descriptive)?
• How does the author of each book support his or her argument? What evidence does each author use to prove his or her point? Do you find that evidence convincing? Why or why not? Does any of the author's information [or conclusions] conflict with other books you've read, courses you've taken, or just previous assumptions you had about the research problem under study?
• How does the author structure his or her argument? What are the parts that make up the whole? Does the argument make sense to you? Does it persuade you? Why or why not?
• How has each book helped you understand the subject? Would you recommend the book to others? Why or why not?

Beyond the content of the book, you may also consider some information about the author and the circumstances of the text's production:

• Who is the author? Nationality, political persuasion, training, intellectual interests, personal history, and historical context may provide crucial details about how a work takes shape. Does it matter, for example, that the author is affiliated with a particular organization? What difference would it make if the author participated in the events he or she writes about? What other topics has the author written about? Does this work build on prior research or does it seem to represent a new area of research?
• What is the book's genre? Out of what discipline does it emerge? Does it conform to or depart from the conventions of its genre? These questions can provide a historical or other contextual standard upon which to base your evaluations. If you are reviewing the first book ever written on the subject, it will be important for your readers to know this. Keep in mind, though, that declarative statements about being the “first,” the "best," or the "only" book of its kind can be a risky unless you're absolutely certain because your professor [presumably] has a much better understanding of the overall research literature.

Structure and Writing Style

I. Bibliographic Information

Provide the essential information about each book using the writing style asked for by your professor [e.g., APA, MLA, Chicago, etc.]. Depending on how your professor wants you to organize your review, the bibliographic information represents the heading of your review. In general, they would be arranged alphabetically by title and look like this:

Racing the Storm: Racial Implications and Lessons Learned from Hurricane Katrina .  Hillary Potter, ed. (Lanham, MD: Lexington Books, 2007. 320 pp) The Sociology of Katrina: Perspectives on a Modern Catastrophe . David L. Brunsma, David Overfelt, and J. Steven Picou, eds. (Lanham, MD: Rowman and Littlefield, 2007. 288 pp.) Through the Eye of Katrina: Social Justice in the United States . Kristin A. Bates and Richelle S. Swan, eds. (Durham, NC: Carolina Academic Press, 2007. 440 pp.) Reviewed by [your name]

II. Thesis Statement

The thesis statement of an essay that compares and contrasts multiple works should contain an idea or claim that unites a discussion of the texts under review . It should include the argument that will be advanced in support of the claims that is being made. To begin, ask yourself: "What is the overarching subject or issue that ties together all of the books?" Why is it important?" In most scholarly works, the author(s) will state the purpose of their book in the preface or in an introductory chapter.

If you cannot find an adequate statement in the author's own words or if you find that the thesis statement is not well-developed, then you will have to compose your own introductory thesis statement that does cover all the material. For a book review essay, this thesis statement will vary in length depending on the number and complxity of books. Regardless of length, it must be succinct, accurate, unbiased, and clear.

If you find it difficult to discern the overall aims and objectives of the book [and, be sure to point this out in your review if you believe it to be a deficiency], you may arrive at an understanding of the purpose by asking yourself a the following questions:

• Why did the author write on this subject rather than on some other subject?
• From what point of view is the work written?
• Was the author trying to give information, to explain something technical, or to convince the reader of a belief’s validity by dramatizing it in action?
• What is the general field or genre, and how does the book fit into it? Review related literature from other books and journal articles to familiarize yourself with the field, if necessary.
• Who is the intended audience?
• What is the author's style? Is it formal or informal? You can evaluate the quality of the writing style by noting some of the following standards: coherence, clarity, originality, forcefulness, correct use of technical words, conciseness, fullness of development, and fluidity.
• Scan the Table of Contents because it can help you understand how the book is organized and will aid in determining the author's main ideas and how they are developed [e.g., chronologically, topically, etc.]
• How did the book affect you? Were any prior assumptions you had on the subject changed, abandoned, or reinforced due to this book? How is the book related to your own course or personal agenda? What personal experiences have you had that relate to the subject?
• How well has the book achieved its goal(s)?
• Would you recommend this book to others? Why or why not?

NOTE : Be sure that your thesis statement includes the rationale behind why your choice of what points to compare and contrast were deliberate and meaningful and not random!

III. Methods of Organization

Organization is critical to writing an essay that compares and contrasts multiple works because you will most likely be discussing a variety of evidence and you must be certain that the logic and narrative flow of your paper can be understood by the reader. Here are some general guidelines to consider:

• If your professor asks you to choose the books to review, identify works that are closely related in some way so they can be easily compared or contrasted.
• Compare according to a single organized idea.
• Choose a method of development [see below] that works well with your organizing idea.
• Use specific and relevant examples to support your analysis.
• Use transitional words or phrases to help the reader understand the similarities and differences in your subject.
• Conclude your paper by restating your thesis, summarizing the main points, and give the reader the final "so what" of the major similarities and/or differences that you discussed. Why are they important?

There are two general methods of organizing your book review essay. If you believe one work extends another, you'll probably use a block method; if you find that two or more works are essentially engaged in a debate, a point-by-point method will help draw attention to the conflict. However, the point-by-point method can come off as a rhetorical ping-pong match. You can avoid this effect by grouping more than one point together, thereby cutting down on the number of times you alternate from one work to another. No matter which method you choose, you do not need to give equal time to similarities and differences. In fact, your paper will be more interesting if you state your main argument(s) as quickly as possible. For example, a book review essay evaluating three research studies that examine different interpretations of conflict resolution among nations in the Middl East might have as few as two or three sentences in the introduction regarding similarities and only a paragraph or two to set up the contrast between the author’s positions. The rest of the essay, whether organized by block method or point-by-point, will be your analysis of the key differences among the books.

The Block Method Present all the information about A, and then present parallel information about B. This pattern tends to work better for shorter book review essays, and those with few sub-topics. The method looks like this:

I. Introduction     A. Briefly introduce the significance of the overall subject matter     B. Thesis Statement         --First supporting point         --Second supporting point         --Third supporting point II. First book     A. Summary of book         --Relationship of work to first point         --Relationship of work to second point         --Relationship of work to third point III. Second book     A. Summary of book         --Relationship of work to first point         --Relationship of work to second point         --Relationship of work to third point IV. Third book     A. Summary of book         --Relationship of work to first point         --Relationship of work to second point         --Relationship of work to third point V. Conclusion     A. Restate thesis     B. Summarize how you proved your argument The Point-by-Point Method Present one point about A, and then go to the parallel point about B. Move to the next point, and do the same thing. This pattern tends to work better for long book review essays and those with many sub-topics. The method looks like this:

I. Introduction     A. Briefly introduce significance of overall subject matter     B. Thesis statement II. Brief explanation of first book III. Brief explanation of second book IV. First comparative point     A. Relation of point to first book     B. Relation of point to second book V. Second comparative point     A. Relation of point to first book     B. Relation of point to second book VI. Third comparative point     A. Relation of point to first book     B. Relation of point to second book VII. Conclusion     A. Restate thesis     B. Summarize how your proved your argument

IV.  Critically Evaluate the Contents

Regardless of whether you choose the block method or the point-by-point method, critical comments should form the bulk of your book review essay . State whether or not you feel the author's treatment of the subject matter is appropriate for the intended audience. Ask yourself:

• Has the purpose of the book been achieved?
• What contribution does the book make to the field?
• Is the treatment of the subject matter objective?
• Are there facts and evidence that have been omitted?
• What kinds of data, if any, are used to support the author's thesis statement?
• Can the same data be interpreted to alternate ends?
• Is the writing style clear and effective?
• Does the book raise important or provocative issues or topics for discussion and further research?
• What has been left out?

Support your evaluation with evidence from each text and, when possible, in relation to other sources. If relevant, make note of each book's format, such as, layout, binding, typography, etc. Are there maps, illustrations? Do they aid in understanding the research problem? This is particular important in books that contain a lot of non-textual elements, such as tables, charts, and illustrations.

NOTE : It is important to carefully distinguish your views from those of the authors, so that you don’t confuse your reader.

V.  Examine the Front Matter and Back Matter

Back matter refers to any information included after the final chapter of the book. Front matter refers to anything before the first chapter. Front matter is most often numbered separately from the rest of the text in lower case Roman numerals [i.e. i-xi ]. Critical commentary about front or back matter is generally only necessary if you believe there is something that diminishes the overall quality of the work or there is something that is particularly helpful in understanding the book's contents.

The following back matter may be included in a book and should be considered for evaluation when reviewing the overall quality of the book:

• Table of contents --is it clear? Does it reflect the true contents of the book?
• Author biography --also found as back matter, the biography of author(s) can be useful in determining the authority of the writer and whether the book builds on prior research or represents new research. In scholarly reviews, noting the author's affiliation can be a factor in helping the reader determine the overall validity of work [i.e., are they associated with a research center devoted to studying the research problem under investigation].
• Foreword --in a scholarly books, a foreword may be written by the author or an expert on the subject of the book. The purpose of a foreword is to introduce the reader to the author as well as the book itself, and attempt to establish credibility for both. A foreword does not contribute any additional information about the book's subject matter, but it serves as a means of validating the book's existence. Later editions of a book sometimes have a new foreword prepended [appearing before an older foreword if there was one], which might explain in what respects that edition differs from previous ones.
• Preface --generally describes the genesis, purpose, limitations, and scope of the book and may include acknowledgments of indebtedness to people who have helped the author complerte the study. Is the preface helpful in understanding the study? Does it effectively provide a framework for what's to follow?
• Chronology --also found as back matter, a chronology is generally included to highlight key events related to the subject of the book. Does it contribute to the overall work? Is it detailed or very general?
• List of non-textual elements --if a book contains a lot of charts, photographs, maps, etc., they will often be listed in the front.
• Afterword --this is a short, reflective piece written by the author that takes the form of a concluding section, final commentary, or closing statement. It is worth mentioning in a review if it contributes information about the purpose of the book, gives a call to action, or asks the reader to consider key points made in the book.
• Appendix --is the supplementary material in the appendix or appendices well organized? Do they relate to the contents or appear superfluous? Does it contain any essential information that would have been more appropriately integrated into the text?
• Index --is the index thorough and accurate? Are there elements such as bold text, to help identify specific parts of the book?
• Glossary --are the definitions clearly written? Is the glossary comprehensive or are key terms missing?
• Endotes/Footnotes --check any end notes or footnotes as you read from chapter to chapter. Do they provide important additional information? Do they clarify or extend points made in the body of the text?
• Bibliography/Further Readings --review any bibliography or further readings the author may have included. What kinds of sources [e.g., primary or secondary, recent or old, scholarly or popular, etc.] appear in the bibliography? How does the author make use of them? Make note of important omissions.

NOTE :  In reviewing multiple works, compare and contrast the quality of the back and front matter. Be sure to highlight works where the front or back matter is particularly well-organized or effective in supplementing the main content.

VI.  Summarize and Comment

Your conclusion should synthesize the key similarities and differences among the books. Avoid stating restating your assessment word for word; your goal is to provide a sense of closure and to leave the reader with a final perspective about the overall subject under review and whether you believe each book has effectively contributed to the overall research literature on the subject. Do not introduce new information or ideas in the conclusion.

What is a Literature Review? How to Write It (with Examples)

A literature review is a critical analysis and synthesis of existing research on a particular topic. It provides an overview of the current state of knowledge, identifies gaps, and highlights key findings in the literature. 1 The purpose of a literature review is to situate your own research within the context of existing scholarship, demonstrating your understanding of the topic and showing how your work contributes to the ongoing conversation in the field. Learning how to write a literature review is a critical tool for successful research. Your ability to summarize and synthesize prior research pertaining to a certain topic demonstrates your grasp on the topic of study, and assists in the learning process.

Frequently asked questions 

What is a literature review .

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example 

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:  

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Conducting a literature review 

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:  

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:  

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:  

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:  

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:  

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:  

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

What is the Difference Between Research Papers and Review Papers?

Researchers often have to write different types of articles, from review papers to review papers and more, each with its own purpose and structure. This makes it critical for students and researchers to understand the nuances of good writing and develop the skills required to write various kinds of academic text. With so many different types of academic writing to pursue – scholarly articles, commentaries, book reviews, case reports, clinical study reports – it is common for students and early career researchers to get confused. So in this article, we will explain what is a review paper and what is a research paper, while summarizing the similarities and difference between review papers and research papers.

Table of Contents

What is a Review Paper ?

A review paper offers an overview of previously published work and does not contain any new research findings. It evaluates and summarizes information or knowledge that is already available in various published formats like journals, books, or other publications, all of which is referred to as secondary literature. Well-written review papers play a crucial role in helping students and researchers understand existing knowledge in a specific field or a research topic they are interested in. By providing a comprehensive overview of previous studies, methodologies, findings, and trends, they help researchers identify gaps in a specific field of study opening up new avenues for future research.

What is a Research Paper ?

A research paper is based on original research and primary sources of data. Unlike review papers, researchers writing research papers need to report new findings derived from empirical research or experimentation. It requires the author to draw inferences or make assumptions based on experiments, surveys, interviews, or questionnaires employed to collect and analyze data. Research papers also typically follow the recommended IMRAD format, which includes an abstract, introduction, methodology, results, discussion, and conclusion. Through research papers, authors address a specific research question or hypothesis with the aim of contributing novel insights to the field.

Similarities between research papers and review papers

Research papers and review papers share several similarities, which makes it understandable that it is this pair of academic documents that are often most confused.

• Research papers and review papers are written by scholars and intended for an academic audience; they’re written with the aim of contributing to the existing body of knowledge in a particular field and can be published in peer reviewed journals.
• Both research papers and review papers require a comprehensive understanding of all the latest, relevant literature on a specific topic. This means authors must conduct a thorough review of existing studies, theories, and methodologies in their own subject and related areas to inform their own research or analysis.
• Research papers and review papers both adhere to specific formatting and citation styles dictated by the target journal. This ensures consistency and allows readers to easily locate and reference the sources cited in the papers.

These similarities highlight the rigorous, scholarly nature of both research papers and review papers, which requires both research integrity and a commitment to further knowledge in a field. However, these two types of academic writing are more different than one would think.

Differences between research papers and review papers

Though often used interchangeably to refer to academic content, research papers and review papers are quite different. They have different purposes, specific structure and writing styles, and citation formats given that they aim to communicate different kinds of information. Here are four key differences between research papers and review papers:

• Purpose: Review papers evaluate existing research, identify trends, and discuss the current state of knowledge on a specific topic; they are based on the study of previously published literature. On the other hand, research paperscontain original research work undertaken by the author, who is required to contribute new knowledge to the research field.
• Structure: Research papers typically follow a structured format, including key sections like the introduction, methods, results, discussion, and conclusion. Meanwhile, review papers may have a more flexible structure, allowing authors to organize the content based on thematic or chronological approaches. However, they generally include an introduction, main body discussing various aspects of the topic, and a conclusion.
• Methodology: Research papers involve the collection of data, experimentation, or analysis of existing data to answer specific research questions. However, review papers do not involve original data collection; instead, they extensively analyze and summarize existing studies, often using systematic literature review methods.
• Citation style: Research papers rely on primary sources to support and justify their own findings, emphasizing recent and relevant research. Review papers incorporate a wide range of primary and secondary sources to present a comprehensive overview of the topic and support the evaluation and synthesis of existing literature.

In summary, it’s important to understand the key differences between research papers and review papers. By mastering the art of writing both research papers and review papers, students and researchers can make more meaningful contributions to their chosen disciplines. All the best!

Review articles present comprehensive overview of relevant literature on specific themes and synthesise the studies related to these themes, with the aim of strengthening the foundation of knowledge and facilitating theory development. The significance of review articles in science is immeasurable as both students and researchers rely on these articles as the starting point for their research. Interestingly, many postgraduate students are expected to write review articles for journal publications as a way of demonstrating their ability to contribute to new knowledge in their respective fields. However, there is no comprehensive instructional framework to guide them on how to analyse and synthesise the literature in their niches into publishable review articles. The dearth of ample guidance or explicit training results in students having to learn all by themselves, usually by trial and error, which often leads to high rejection rates from publishing houses. Therefore, this article seeks to identify these challenges from a beginner's perspective and strives to plug the identified gaps and discrepancies. Thus, the purpose of this paper is to serve as a systematic guide for emerging scientists and to summarise the most important information on how to write and structure a publishable review article.

1. Introduction

Early scientists, spanning from the Ancient Egyptian civilization to the Scientific Revolution of the 16 th /17 th century, based their research on intuitions, personal observations, and personal insights. Thus, less time was spent on background reading as there was not much literature to refer to. This is well illustrated in the case of Sir Isaac Newton's apple tree and the theory of gravity, as well as Gregor Mendel's pea plants and the theory of inheritance. However, with the astronomical expansion in scientific knowledge and the emergence of the information age in the last century, new ideas are now being built on previously published works, thus the periodic need to appraise the huge amount of already published literature [ 1 ]. According to Birkle et al. [ 2 ], the Web of Science—an authoritative database of research publications and citations—covered more than 80 million scholarly materials. Hence, a critical review of prior and relevant literature is indispensable for any research endeavour as it provides the necessary framework needed for synthesising new knowledge and for highlighting new insights and perspectives [ 3 ].

Review papers are generally considered secondary research publications that sum up already existing works on a particular research topic or question and relate them to the current status of the topic. This makes review articles distinctly different from scientific research papers. While the primary aim of the latter is to develop new arguments by reporting original research, the former is focused on summarising and synthesising previous ideas, studies, and arguments, without adding new experimental contributions. Review articles basically describe the content and quality of knowledge that are currently available, with a special focus on the significance of the previous works. To this end, a review article cannot simply reiterate a subject matter, but it must contribute to the field of knowledge by synthesising available materials and offering a scholarly critique of theory [ 4 ]. Typically, these articles critically analyse both quantitative and qualitative studies by scrutinising experimental results, the discussion of the experimental data, and in some instances, previous review articles to propose new working theories. Thus, a review article is more than a mere exhaustive compilation of all that has been published on a topic; it must be a balanced, informative, perspective, and unbiased compendium of previous studies which may also include contrasting findings, inconsistencies, and conventional and current views on the subject [ 5 ].

Hence, the essence of a review article is measured by what is achieved, what is discovered, and how information is communicated to the reader [ 6 ]. According to Steward [ 7 ], a good literature review should be analytical, critical, comprehensive, selective, relevant, synthetic, and fully referenced. On the other hand, a review article is considered to be inadequate if it is lacking in focus or outcome, overgeneralised, opinionated, unbalanced, and uncritical [ 7 ]. Most review papers fail to meet these standards and thus can be viewed as mere summaries of previous works in a particular field of study. In one of the few studies that assessed the quality of review articles, none of the 50 papers that were analysed met the predefined criteria for a good review [ 8 ]. However, beginners must also realise that there is no bad writing in the true sense; there is only writing in evolution and under refinement. Literally, every piece of writing can be improved upon, right from the first draft until the final published manuscript. Hence, a paper can only be referred to as bad and unfixable when the author is not open to corrections or when the writer gives up on it.

According to Peat et al. [ 9 ], “everything is easy when you know how,” a maxim which applies to scientific writing in general and review writing in particular. In this regard, the authors emphasized that the writer should be open to learning and should also follow established rules instead of following a blind trial-and-error approach. In contrast to the popular belief that review articles should only be written by experienced scientists and researchers, recent trends have shown that many early-career scientists, especially postgraduate students, are currently expected to write review articles during the course of their studies. However, these scholars have little or no access to formal training on how to analyse and synthesise the research literature in their respective fields [ 10 ]. Consequently, students seeking guidance on how to write or improve their literature reviews are less likely to find published works on the subject, particularly in the science fields. Although various publications have dealt with the challenges of searching for literature, or writing literature reviews for dissertation/thesis purposes, there is little or no information on how to write a comprehensive review article for publication. In addition to the paucity of published information to guide the potential author, the lack of understanding of what constitutes a review paper compounds their challenges. Thus, the purpose of this paper is to serve as a guide for writing review papers for journal publishing. This work draws on the experience of the authors to assist early-career scientists/researchers in the “hard skill” of authoring review articles. Even though there is no single path to writing scientifically, or to writing reviews in particular, this paper attempts to simplify the process by looking at this subject from a beginner's perspective. Hence, this paper highlights the differences between the types of review articles in the sciences while also explaining the needs and purpose of writing review articles. Furthermore, it presents details on how to search for the literature as well as how to structure the manuscript to produce logical and coherent outputs. It is hoped that this work will ease prospective scientific writers into the challenging but rewarding art of writing review articles.

2. Benefits of Review Articles to the Author

Analysing literature gives an overview of the “WHs”: WHat has been reported in a particular field or topic, WHo the key writers are, WHat are the prevailing theories and hypotheses, WHat questions are being asked (and answered), and WHat methods and methodologies are appropriate and useful [ 11 ]. For new or aspiring researchers in a particular field, it can be quite challenging to get a comprehensive overview of their respective fields, especially the historical trends and what has been studied previously. As such, the importance of review articles to knowledge appraisal and contribution cannot be overemphasised, which is reflected in the constant demand for such articles in the research community. However, it is also important for the author, especially the first-time author, to recognise the importance of his/her investing time and effort into writing a quality review article.

Generally, literature reviews are undertaken for many reasons, mainly for publication and for dissertation purposes. The major purpose of literature reviews is to provide direction and information for the improvement of scientific knowledge. They also form a significant component in the research process and in academic assessment [ 12 ]. There may be, however, a thin line between a dissertation literature review and a published review article, given that with some modifications, a literature review can be transformed into a legitimate and publishable scholarly document. According to Gülpınar and Güçlü [ 6 ], the basic motivation for writing a review article is to make a comprehensive synthesis of the most appropriate literature on a specific research inquiry or topic. Thus, conducting a literature review assists in demonstrating the author's knowledge about a particular field of study, which may include but not be limited to its history, theories, key variables, vocabulary, phenomena, and methodologies [ 10 ]. Furthermore, publishing reviews is beneficial as it permits the researchers to examine different questions and, as a result, enhances the depth and diversity of their scientific reasoning [ 1 ]. In addition, writing review articles allows researchers to share insights with the scientific community while identifying knowledge gaps to be addressed in future research. The review writing process can also be a useful tool in training early-career scientists in leadership, coordination, project management, and other important soft skills necessary for success in the research world [ 13 ]. Another important reason for authoring reviews is that such publications have been observed to be remarkably influential, extending the reach of an author in multiple folds of what can be achieved by primary research papers [ 1 ]. The trend in science is for authors to receive more citations from their review articles than from their original research articles. According to Miranda and Garcia-Carpintero [ 14 ], review articles are, on average, three times more frequently cited than original research articles; they also asserted that a 20% increase in review authorship could result in a 40–80% increase in citations of the author. As a result, writing reviews can significantly impact a researcher's citation output and serve as a valuable channel to reach a wider scientific audience. In addition, the references cited in a review article also provide the reader with an opportunity to dig deeper into the topic of interest. Thus, review articles can serve as a valuable repository for consultation, increasing the visibility of the authors and resulting in more citations.

3. Types of Review Articles

The first step in writing a good literature review is to decide on the particular type of review to be written; hence, it is important to distinguish and understand the various types of review articles. Although scientific review articles have been classified according to various schemes, however, they are broadly categorised into narrative reviews, systematic reviews, and meta-analyses [ 15 ]. It was observed that more authors—as well as publishers—were leaning towards systematic reviews and meta-analysis while downplaying narrative reviews; however, the three serve different aims and should all be considered equally important in science [ 1 ]. Bibliometric reviews and patent reviews, which are closely related to meta-analysis, have also gained significant attention recently. However, from another angle, a review could also be of two types. In the first class, authors could deal with a widely studied topic where there is already an accumulated body of knowledge that requires analysis and synthesis [ 3 ]. At the other end of the spectrum, the authors may have to address an emerging issue that would benefit from exposure to potential theoretical foundations; hence, their contribution would arise from the fresh theoretical foundations proposed in developing a conceptual model [ 3 ].

3.1. Narrative Reviews

Narrative reviewers are mainly focused on providing clarification and critical analysis on a particular topic or body of literature through interpretative synthesis, creativity, and expert judgement. According to Green et al. [ 16 ], a narrative review can be in the form of editorials, commentaries, and narrative overviews. However, editorials and commentaries are usually expert opinions; hence, a beginner is more likely to write a narrative overview, which is more general and is also referred to as an unsystematic narrative review. Similarly, the literature review section of most dissertations and empirical papers is typically narrative in nature. Typically, narrative reviews combine results from studies that may have different methodologies to address different questions or to formulate a broad theoretical formulation [ 1 ]. They are largely integrative as strong focus is placed on the assimilation and synthesis of various aspects in the review, which may involve comparing and contrasting research findings or deriving structured implications [ 17 ]. In addition, they are also qualitative studies because they do not follow strict selection processes; hence, choosing publications is relatively more subjective and unsystematic [ 18 ]. However, despite their popularity, there are concerns about their inherent subjectivity. In many instances, when the supporting data for narrative reviews are examined more closely, the evaluations provided by the author(s) become quite questionable [ 19 ]. Nevertheless, if the goal of the author is to formulate a new theory that connects diverse strands of research, a narrative method is most appropriate.

3.2. Systematic Reviews

In contrast to narrative reviews, which are generally descriptive, systematic reviews employ a systematic approach to summarise evidence on research questions. Hence, systematic reviews make use of precise and rigorous criteria to identify, evaluate, and subsequently synthesise all relevant literature on a particular topic [ 12 , 20 ]. As a result, systematic reviews are more likely to inspire research ideas by identifying knowledge gaps or inconsistencies, thus helping the researcher to clearly define the research hypotheses or questions [ 21 ]. Furthermore, systematic reviews may serve as independent research projects in their own right, as they follow a defined methodology to search and combine reliable results to synthesise a new database that can be used for a variety of purposes [ 22 ]. Typically, the peculiarities of the individual reviewer, different search engines, and information databases used all ensure that no two searches will yield the same systematic results even if the searches are conducted simultaneously and under identical criteria [ 11 ]. Hence, attempts are made at standardising the exercise via specific methods that would limit bias and chance effects, prevent duplications, and provide more accurate results upon which conclusions and decisions can be made.

The most established of these methods is the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines which objectively defined statements, guidelines, reporting checklists, and flowcharts for undertaking systematic reviews as well as meta-analysis [ 23 ]. Though mainly designed for research in medical sciences, the PRISMA approach has gained wide acceptance in other fields of science and is based on eight fundamental propositions. These include the explicit definition of the review question, an unambiguous outline of the study protocol, an objective and exhaustive systematic review of reputable literature, and an unambiguous identification of included literature based on defined selection criteria [ 24 ]. Other considerations include an unbiased appraisal of the quality of the selected studies (literature), organic synthesis of the evidence of the study, preparation of the manuscript based on the reporting guidelines, and periodic update of the review as new data emerge [ 24 ]. Other methods such as PRISMA-P (Preferred Reporting Items for Systematic review and Meta-Analysis Protocols), MOOSE (Meta-analysis Of Observational Studies in Epidemiology), and ROSES (Reporting Standards for Systematic Evidence Syntheses) have since been developed for systematic reviews (and meta-analysis), with most of them being derived from PRISMA.

Consequently, systematic reviews—unlike narrative reviews—must contain a methodology section which in addition to all that was highlighted above must fully describe the precise criteria used in formulating the research question and setting the inclusion or exclusion criteria used in selecting/accessing the literature. Similarly, the criteria for evaluating the quality of the literature included in the review as well as for analysing, synthesising, and disseminating the findings must be fully described in the methodology section.

3.3. Meta-Analysis

Meta-analyses are considered as more specialised forms of systematic reviews. Generally, they combine the results of many studies that use similar or closely related methods to address the same question or share a common quantitative evaluation method [ 25 ]. However, meta-analyses are also a step higher than other systematic reviews as they are focused on numerical data and involve the use of statistics in evaluating different studies and synthesising new knowledge. The major advantage of this type of review is the increased statistical power leading to more reliable results for inferring modest associations and a more comprehensive understanding of the true impact of a research study [ 26 ]. Unlike in traditional systematic reviews, research topics covered in meta-analyses must be mature enough to allow the inclusion of sufficient homogeneous empirical research in terms of subjects, interventions, and outcomes [ 27 , 28 ].

Being an advanced form of systematic review, meta-analyses must also have a distinct methodology section; hence, the standard procedures involved in the traditional systematic review (especially PRISMA) also apply in meta-analyses [ 23 ]. In addition to the common steps in formulating systematic reviews, meta-analyses are required to describe how nested and missing data are handled, the effect observed in each study, the confidence interval associated with each synthesised effect, and any potential for bias presented within the sample(s) [ 17 ]. According to Paul and Barari [ 28 ], a meta-analysis must also detail the final sample, the meta-analytic model, and the overall analysis, moderator analysis, and software employed. While the overall analysis involves the statistical characterization of the relationships between variables in the meta-analytic framework and their significance, the moderator analysis defines the different variables that may affect variations in the original studies [ 28 , 29 ]. It must also be noted that the accuracy and reliability of meta-analyses have both been significantly enhanced by the incorporation of statistical approaches such as Bayesian analysis [ 30 ], network analysis [ 31 ], and more recently, machine learning [ 32 ].

3.4. Bibliometric Review

A bibliometric review, commonly referred to as bibliometric analysis, is a systematic evaluation of published works within a specific field or discipline [ 33 ]. This bibliometric methodology involves the use of quantitative methods to analyse bibliometric data such as the characteristics and numbers of publications, units of citations, authorship, co-authorship, and journal impact factors [ 34 ]. Academics use bibliometric analysis with different objectives in mind, which includes uncovering emerging trends in article and journal performance, elaborating collaboration patterns and research constituents, evaluating the impact and influence of particular authors, publications, or research groups, and highlighting the intellectual framework of a certain field [ 35 ]. It is also used to inform policy and decision-making. Similarly to meta-analysis, bibliometric reviews rely upon quantitative techniques, thus avoiding the interpretation bias that could arise from the qualitative techniques of other types of reviews [ 36 ]. However, while bibliometric analysis synthesises the bibliometric and intellectual structure of a field by examining the social and structural linkages between various research parts, meta-analysis focuses on summarising empirical evidence by probing the direction and strength of effects and relationships among variables, especially in open research questions [ 37 , 38 ]. However, similarly to systematic review and meta-analysis, a bibliometric review also requires a well-detailed methodology section. The amount of data to be analysed in bibliometric analysis is quite massive, running to hundreds and tens of thousands in some cases. Although the data are objective in nature (e.g., number of citations and publications and occurrences of keywords and topics), the interpretation is usually carried out through both objective (e.g., performance analysis) and subjective (e.g., thematic analysis) evaluations [ 35 ]. However, the invention and availability of bibliometric software such as BibExcel, Gephi, Leximancer, and VOSviewer and scientific databases such as Dimensions, Web of Science, and Scopus have made this type of analysis more feasible.

3.5. Patent Review

Patent reviews provide a comprehensive analysis and critique of a specific patent or a group of related patents, thus presenting a concise understanding of the technology or innovation that is covered by the patent [ 39 ]. This type of article is useful for researchers as it also enhances their understanding of the legal, technical, and commercial aspects of an intellectual property/innovation; in addition, it is also important for stakeholders outside the research community including IP (intellectual property) specialists, legal professionals, and technology-transfer officers [ 40 ]. Typically, patent reviews encompass the scope, background, claims, legal implications, technical specifications, and potential commercial applications of the patent(s). The article may also include a discussion of the patent's strengths and weaknesses, as well as its potential impact on the industry or field in which it operates. Most times, reviews are time specified, they may be regionalised, and the data are usually retrieved via patent searches on databases such as that of the European Patent Office ( https://www.epo.org/searching.html ), United States Patent and Trademark Office ( https://patft.uspto.gov/ ), the World Intellectual Property Organization's PATENTSCOPE ( https://patentscope.wipo.int/search/en/structuredSearch.jsf ), Google Patent ( https://www.google.com/?tbm=pts ), and China National Intellectual Property Administration ( https://pss-system.cponline.cnipa.gov.cn/conventionalSearch ). According to Cerimi et al. [ 41 ], the retrieved data and analysed may include the patent number, patent status, filing date, application date, grant dates, inventor, assignee, and pending applications. While data analysis is usually carried out by general data software such as Microsoft Excel, an intelligence software solely dedicated to patent research and analysis, Orbit Intelligence has been found to be more efficient [ 39 ]. It is also mandatory to include a methodology section in a patent review, and this should be explicit, thorough, and precise to allow a clear understanding of how the analysis was carried out and how the conclusions were arrived at.

4. Searching Literature

One of the most challenging tasks in writing a review article on a subject is the search for relevant literature to populate the manuscript as the author is required to garner information from an endless number of sources. This is even more challenging as research outputs have been increasing astronomically, especially in the last decade, with thousands of new articles published annually in various fields. It is therefore imperative that the author must not only be aware of the overall trajectory in a field of investigation but must also be cognizant of recent studies so as not to publish outdated research or review articles. Basically, the search for the literature involves a coherent conceptual structuring of the topic itself and a thorough collation of evidence under the common themes which might reflect the histories, conflicts, standoffs, revolutions, and/or evolutions in the field [ 7 ]. To start the search process, the author must carefully identify and select broad keywords relevant to the subject; subsequently, the keywords should be developed to refine the search into specific subheadings that would facilitate the structure of the review.

Two main tactics have been identified for searching the literature, namely, systematic and snowballing [ 42 ]. The systematic approach involves searching literature with specific keywords (for example, cancer, antioxidant, and nanoparticles), which leads to an almost unmanageable and overwhelming list of possible sources [ 43 ]. The snowballing approach, however, involves the identification of a particular publication, followed by the compilation of a bibliography of articles based on the reference list of the identified publication [ 44 ]. Many times, it might be necessary to combine both approaches, but irrespective, the author must keep an accurate track and record of papers cited in the search. A simple and efficient strategy for populating the bibliography of review articles is to go through the abstract (and sometimes the conclusion) of a paper; if the abstract is related to the topic of discourse, the author might go ahead and read the entire article; otherwise, he/she is advised to move on [ 45 ]. Winchester and Salji [ 5 ] noted that to learn the background of the subject/topic to be reviewed, starting literature searches with academic textbooks or published review articles is imperative, especially for beginners. Furthermore, it would also assist in compiling the list of keywords, identifying areas of further exploration, and providing a glimpse of the current state of the research. However, past reviews ideally are not to serve as the foundation of a new review as they are written from someone else's viewpoint, which might have been tainted with some bias. Fortunately, the accessibility and search for the literature have been made relatively easier than they were a few decades ago as the current information age has placed an enormous volume of knowledge right at our fingertips [ 46 ]. Nevertheless, when gathering the literature from the Internet, authors should exercise utmost caution as much of the information may not be verified or peer-reviewed and thus may be unregulated and unreliable. For instance, Wikipedia, despite being a large repository of information with more than 6.7 million articles in the English language alone, is considered unreliable for scientific literature reviews, due to its openness to public editing [ 47 ]. However, in addition to peer-reviewed journal publications—which are most ideal—reviews can also be drawn from a wide range of other sources such as technical documents, in-house reports, conference abstracts, and conference proceedings. Similarly, “Google Scholar”—as against “Google” and other general search engines—is more appropriate as its searches are restricted to only academic articles produced by scholarly societies or/and publishers [ 48 ]. Furthermore, the various electronic databases, such as ScienceDirect, Web of Science, PubMed, and MEDLINE, many of which focus on specific fields of research, are also ideal options [ 49 ]. Advancement in computer indexing has remarkably expanded the ease and ability to search large databases for every potentially relevant article. In addition to searching by topic, literature search can be modified by time; however, there must be a balance between old papers and recent ones. The general consensus in science is that publications less than five years old are considered recent.

It is important, especially in systematic reviews and meta-analyses, that the specific method of running the computer searches be properly documented as there is the need to include this in the method (methodology) section of such papers. Typically, the method details the keywords, databases explored, search terms used, and the inclusion/exclusion criteria applied in the selection of data and any other specific decision/criteria. All of these will ensure the reproducibility and thoroughness of the search and the selection procedure. However, Randolph [ 10 ] noted that Internet searches might not give the exhaustive list of articles needed for a review article; hence, it is advised that authors search through the reference lists of articles that were obtained initially from the Internet search. After determining the relevant articles from the list, the author should read through the references of these articles and repeat the cycle until saturation is reached [ 10 ]. After populating the articles needed for the literature review, the next step is to analyse them individually and in their whole entirety. A systematic approach to this is to identify the key information within the papers, examine them in depth, and synthesise original perspectives by integrating the information and making inferences based on the findings. In this regard, it is imperative to link one source to the other in a logical manner, for instance, taking note of studies with similar methodologies, papers that agree, or results that are contradictory [ 42 ].

5. Structuring the Review Article

The title and abstract are the main selling points of a review article, as most readers will only peruse these two elements and usually go on to read the full paper if they are drawn in by either or both of the two. Tullu [ 50 ] recommends that the title of a scientific paper “should be descriptive, direct, accurate, appropriate, interesting, concise, precise, unique, and not be misleading.” In addition to providing “just enough details” to entice the reader, words in the titles are also used by electronic databases, journal websites, and search engines to index and retrieve a particular paper during a search [ 51 ]. Titles are of different types and must be chosen according to the topic under review. They are generally classified as descriptive, declarative, or interrogative and can also be grouped into compound, nominal, or full-sentence titles [ 50 ]. The subject of these categorisations has been extensively discussed in many articles; however, the reader must also be aware of the compound titles, which usually contain a main title and a subtitle. Typically, subtitles provide additional context—to the main title—and they may specify the geographic scope of the research, research methodology, or sample size [ 52 ].

Just like primary research articles, there are many debates about the optimum length of a review article's title. However, the general consensus is to keep the title as brief as possible while not being too general. A title length between 10 and 15 words is recommended, since longer titles can be more challenging to comprehend. Paiva et al. [ 53 ] observed that articles which contain 95 characters or less get more views and citations. However, emphasis must be placed on conciseness as the audience will be more satisfied if they can understand what exactly the review has contributed to the field, rather than just a hint about the general topic area. Authors should also endeavour to stick to the journal's specific requirements, especially regarding the length of the title and what they should or should not contain [ 9 ]. Thus, avoidance of filler words such as “a review on/of,” “an observation of,” or “a study of” is a very simple way to limit title length. In addition, abbreviations or acronyms should be avoided in the title, except the standard or commonly interpreted ones such as AIDS, DNA, HIV, and RNA. In summary, to write an effective title, the authors should consider the following points. What is the paper about? What was the methodology used? What were the highlights and major conclusions? Subsequently, the author should list all the keywords from these answers, construct a sentence from these keywords, and finally delete all redundant words from the sentence title. It is also possible to gain some ideas by scanning indices and article titles in major journals in the field. It is important to emphasise that a title is not chosen and set in stone, and the title is most likely to be continually revised and adjusted until the end of the writing process.

5.2. Abstract

The abstract, also referred to as the synopsis, is a summary of the full research paper; it is typically independent and can stand alone. For most readers, a publication does not exist beyond the abstract, partly because abstracts are often the only section of a paper that is made available to the readers at no cost, whereas the full paper may attract a payment or subscription [ 54 ]. Thus, the abstract is supposed to set the tone for the few readers who wish to read the rest of the paper. It has also been noted that the abstract gives the first impression of a research work to journal editors, conference scientific committees, or referees, who might outright reject the paper if the abstract is poorly written or inadequate [ 50 ]. Hence, it is imperative that the abstract succinctly represents the entire paper and projects it positively. Just like the title, abstracts have to be balanced, comprehensive, concise, functional, independent, precise, scholarly, and unbiased and not be misleading [ 55 ]. Basically, the abstract should be formulated using keywords from all the sections of the main manuscript. Thus, it is pertinent that the abstract conveys the focus, key message, rationale, and novelty of the paper without any compromise or exaggeration. Furthermore, the abstract must be consistent with the rest of the paper; as basic as this instruction might sound, it is not to be taken for granted. For example, a study by Vrijhoef and Steuten [ 56 ] revealed that 18–68% of 264 abstracts from some scientific journals contained information that was inconsistent with the main body of the publications.

Abstracts can either be structured or unstructured; in addition, they can further be classified as either descriptive or informative. Unstructured abstracts, which are used by many scientific journals, are free flowing with no predefined subheadings, while structured abstracts have specific subheadings/subsections under which the abstract needs to be composed. Structured abstracts have been noted to be more informative and are usually divided into subsections which include the study background/introduction, objectives, methodology design, results, and conclusions [ 57 ]. No matter the style chosen, the author must carefully conform to the instructions provided by the potential journal of submission, which may include but are not limited to the format, font size/style, word limit, and subheadings [ 58 ]. The word limit for abstracts in most scientific journals is typically between 150 and 300 words. It is also a general rule that abstracts do not contain any references whatsoever.

Typically, an abstract should be written in the active voice, and there is no such thing as a perfect abstract as it could always be improved on. It is advised that the author first makes an initial draft which would contain all the essential parts of the paper, which could then be polished subsequently. The draft should begin with a brief background which would lead to the research questions. It might also include a general overview of the methodology used (if applicable) and importantly, the major results/observations/highlights of the review paper. The abstract should end with one or few sentences about any implications, perspectives, or future research that may be developed from the review exercise. Finally, the authors should eliminate redundant words and edit the abstract to the correct word count permitted by the journal [ 59 ]. It is always beneficial to read previous abstracts published in the intended journal, related topics/subjects from other journals, and other reputable sources. Furthermore, the author should endeavour to get feedback on the abstract especially from peers and co-authors. As the abstract is the face of the whole paper, it is best that it is the last section to be finalised, as by this time, the author would have developed a clearer understanding of the findings and conclusions of the entire paper.

5.3. Graphical Abstracts

Since the mid-2000s, an increasing number of journals now require authors to provide a graphical abstract (GA) in addition to the traditional written abstract, to increase the accessibility of scientific publications to readers [ 60 ]. A study showed that publications with GA performed better than those without it, when the abstract views, total citations, and downloads were compared [ 61 ]. However, the GA should provide “a single, concise pictorial, and visual summary of the main findings of an article” [ 62 ]. Although they are meant to be a stand-alone summary of the whole paper, it has been noted that they are not so easily comprehensible without having read through the traditionally written abstract [ 63 ]. It is important to note that, like traditional abstracts, many reputable journals require GAs to adhere to certain specifications such as colour, dimension, quality, file size, and file format (usually JPEG/JPG, PDF, PNG, or TIFF). In addition, it is imperative to use engaging and accurate figures, all of which must be synthesised in order to accurately reflect the key message of the paper. Currently, there are various online or downloadable graphical tools that can be used for creating GAs, such as Microsoft Paint or PowerPoint, Mindthegraph, ChemDraw, CorelDraw, and BioRender.

5.4. Keywords

As a standard practice, journals require authors to select 4–8 keywords (or phrases), which are typically listed below the abstract. A good set of keywords will enable indexers and search engines to find relevant papers more easily and can be considered as a very concise abstract [ 64 ]. According to Dewan and Gupta [ 51 ], the selection of appropriate keywords will significantly enhance the retrieval, accession, and consequently, the citation of the review paper. Ideally, keywords can be variants of the terms/phrases used in the title, the abstract, and the main text, but they should ideally not be the exact words in the main title. Choosing the most appropriate keywords for a review article involves listing down the key terms and phrases in the article, including abbreviations. Subsequently, a quick review of the glossary/vocabulary/term list or indexing standard in the specific discipline will assist in selecting the best and most precise keywords that match those used in the databases from the list drawn. In addition, the keywords should not be broad or general terms (e.g., DNA, biology, and enzymes) but must be specific to the field or subfield of study as well as to the particular paper [ 65 ].

5.5. Introduction

The introduction of an article is the first major section of the manuscript, and it presents basic information to the reader without compelling them to study past publications. In addition, the introduction directs the reader to the main arguments and points developed in the main body of the article while clarifying the current state of knowledge in that particular area of research [ 12 ]. The introduction part of a review article is usually sectionalised into background information, a description of the main topic and finally a statement of the main purpose of the review [ 66 ]. Authors may begin the introduction with brief general statements—which provide background knowledge on the subject matter—that lead to more specific ones [ 67 ]. It is at this point that the reader's attention must be caught as the background knowledge must highlight the importance and justification for the subject being discussed, while also identifying the major problem to be addressed [ 68 ]. In addition, the background should be broad enough to attract even nonspecialists in the field to maximise the impact and widen the reach of the article. All of these should be done in the light of current literature; however, old references may also be used for historical purposes. A very important aspect of the introduction is clearly stating and establishing the research problem(s) and how a review of the particular topic contributes to those problem(s). Thus, the research gap which the paper intends to fill, the limitations of previous works and past reviews, if available, and the new knowledge to be contributed must all be highlighted. Inadequate information and the inability to clarify the problem will keep readers (who have the desire to obtain new information) from reading beyond the introduction [ 69 ]. It is also pertinent that the author establishes the purpose of reviewing the literature and defines the scope as well as the major synthesised point of view. Furthermore, a brief insight into the criteria used to select, evaluate, and analyse the literature, as well as the outline or sequence of the review, should be provided in the introduction. Subsequently, the specific objectives of the review article must be presented. The last part of the “introduction” section should focus on the solution, the way forward, the recommendations, and the further areas of research as deduced from the whole review process. According to DeMaria [ 70 ], clearly expressed or recommended solutions to an explicitly revealed problem are very important for the wholesomeness of the “introduction” section. It is believed that following these steps will give readers the opportunity to track the problems and the corresponding solution from their own perspective in the light of current literature. As against some suggestions that the introduction should be written only in present tenses, it is also believed that it could be done with other tenses in addition to the present tense. In this regard, general facts should be written in the present tense, specific research/work should be in the past tense, while the concluding statement should be in the past perfect or simple past. Furthermore, many of the abbreviations to be used in the rest of the manuscript and their explanations should be defined in this section.

5.6. Methodology

Writing a review article is equivalent to conducting a research study, with the information gathered by the author (reviewer) representing the data. Like all major studies, it involves conceptualisation, planning, implementation, and dissemination [ 71 ], all of which may be detailed in a methodology section, if necessary. Hence, the methodological section of a review paper (which can also be referred to as the review protocol) details how the relevant literature was selected and how it was analysed as well as summarised. The selection details may include, but are not limited to, the database consulted and the specific search terms used together with the inclusion/exclusion criteria. As earlier highlighted in Section 3 , a description of the methodology is required for all types of reviews except for narrative reviews. This is partly because unlike narrative reviews, all other review articles follow systematic approaches which must ensure significant reproducibility [ 72 ]. Therefore, where necessary, the methods of data extraction from the literature and data synthesis must also be highlighted as well. In some cases, it is important to show how data were combined by highlighting the statistical methods used, measures of effect, and tests performed, as well as demonstrating heterogeneity and publication bias [ 73 ].

The methodology should also detail the major databases consulted during the literature search, e.g., Dimensions, ScienceDirect, Web of Science, MEDLINE, and PubMed. For meta-analysis, it is imperative to highlight the software and/or package used, which could include Comprehensive Meta-Analysis, OpenMEE, Review Manager (RevMan), Stata, SAS, and R Studio. It is also necessary to state the mathematical methods used for the analysis; examples of these include the Bayesian analysis, the Mantel–Haenszel method, and the inverse variance method. The methodology should also state the number of authors that carried out the initial review stage of the study, as it has been recommended that at least two reviews should be done blindly and in parallel, especially when it comes to the acquisition and synthesis of data [ 74 ]. Finally, the quality and validity assessment of the publication used in the review must be stated and well clarified [ 73 ].

5.7. Main Body of the Review

Ideally, the main body of a publishable review should answer these questions: What is new (contribution)? Why so (logic)? So what (impact)? How well it is done (thoroughness)? The flow of the main body of a review article must be well organised to adequately maintain the attention of the readers as well as guide them through the section. It is recommended that the author should consider drawing a conceptual scheme of the main body first, using methods such as mind-mapping. This will help create a logical flow of thought and presentation, while also linking the various sections of the manuscript together. According to Moreira [ 75 ], “reports do not simply yield their findings, rather reviewers make them yield,” and thus, it is the author's responsibility to transform “resistant” texts into “docile” texts. Hence, after the search for the literature, the essential themes and key concepts of the review paper must be identified and synthesised together. This synthesis primarily involves creating hypotheses about the relationships between the concepts with the aim of increasing the understanding of the topic being reviewed. The important information from the various sources should not only be summarised, but the significance of studies must be related back to the initial question(s) posed by the review article. Furthermore, MacLure [ 76 ] stated that data are not just to be plainly “extracted intact” and “used exactly as extracted,” but must be modified, reconfigured, transformed, transposed, converted, tabulated, graphed, or manipulated to enable synthesis, combination, and comparison. Therefore, different pieces of information must be extracted from the reports in which they were previously deposited and then refined into the body of the new article [ 75 ]. To this end, adequate comparison and combination might require that “qualitative data be quantified” or/and “quantitative data may be qualitized” [ 77 ]. In order to accomplish all of these goals, the author may have to transform, paraphrase, generalize, specify, and reorder the text [ 78 ]. For comprehensiveness, the body paragraphs should be arranged in a similar order as it was initially stated in the abstract or/and introduction. Thus, the main body could be divided into thematic areas, each of which could be independently comprehensive and treated as a mini review. Similarly, the sections can also be arranged chronologically depending on the focus of the review. Furthermore, the abstractions should proceed from a wider general view of the literature being reviewed and then be narrowed down to the specifics. In the process, deep insights should also be provided between the topic of the review and the wider subject area, e.g., fungal enzymes and enzymes in general. The abstractions must also be discussed in more detail by presenting more specific information from the identified sources (with proper citations of course!). For example, it is important to identify and highlight contrary findings and rival interpretations as well as to point out areas of agreement or debate among different bodies of literature. Often, there are previous reviews on the same topic/concept; however, this does not prevent a new author from writing one on the same topic, especially if the previous reviews were written many years ago. However, it is important that the body of the new manuscript be written from a new angle that was not adequately covered in the past reviews and should also incorporate new studies that have accumulated since the last review(s). In addition, the new review might also highlight the approaches, limitations, and conclusions of the past studies. But the authors must not be excessively critical of the past reviews as this is regarded by many authors as a sign of poor professionalism [ 3 , 79 ]. Daft [ 79 ] emphasized that it is more important for a reviewer to state how their research builds on previous work instead of outright claiming that previous works are incompetent and inadequate. However, if a series of related papers on one topic have a common error or research flaw that needs rectification, the reviewer must point this out with the aim of moving the field forward [ 3 ]. Like every other scientific paper, the main body of a review article also needs to be consistent in style, for example, in the choice of passive vs. active voice and present vs. past tense. It is also important to note that tables and figures can serve as a powerful tool for highlighting key points in the body of the review, and they are now considered core elements of reviews. For more guidance and insights into what should make up the contents of a good review article, readers are also advised to get familiarised with the Boote and Beile [ 80 ] literature review scoring rubric as well as the review article checklist of Short [ 81 ].

5.8. Tables and Figures

An ideal review article should be logically structured and efficiently utilise illustrations, in the form of tables and figures, to convey the key findings and relationships in the study. According to Tay [ 13 ], illustrations often take a secondary role in review papers when compared to primary research papers which are focused on illustrations. However, illustrations are very important in review articles as they can serve as succinct means of communicating major findings and insights. Franzblau and Chung [ 82 ] pointed out that illustrations serve three major purposes in a scientific article: they simplify complex data and relationships for better understanding, they minimise reading time by summarising and bringing to focus on the key findings (or trends), and last, they help to reduce the overall word count. Hence, inserting and constructing illustrations in a review article is as meticulous as it is important. However, important decisions should be made on whether the charts, figures, or tables to be potentially inserted in the manuscript are indeed needed and how best to design them [ 83 ]. Illustrations should enhance the text while providing necessary information; thus, the information described in illustrations should not contradict that in the main text and should also not be a repetition of texts [ 84 ]. Furthermore, illustrations must be autonomous, meaning they ought to be intelligible without having to read the text portion of the manuscript; thus, the reader does not have to flip back and forth between the illustration and the main text in order to understand it [ 85 ]. It should be noted that tables or figures that directly reiterate the main text or contain extraneous information will only make a mess of the manuscript and discourage readers [ 86 ].

Kotz and Cals [ 87 ] recommend that the layout of tables and figures should be carefully designed in a clear manner with suitable layouts, which will allow them to be referred to logically and chronologically in the text. In addition, illustrations should only contain simple text, as lengthy details would contradict their initial objective, which was to provide simple examples or an overview. Furthermore, the use of abbreviations in illustrations, especially tables, should be avoided if possible. If not, the abbreviations should be defined explicitly in the footnotes or legends of the illustration [ 88 ]. Similarly, numerical values in tables and graphs should also be correctly approximated [ 84 ]. It is recommended that the number of tables and figures in the manuscript should not exceed the target journal's specification. According to Saver [ 89 ], they ideally should not account for more than one-third of the manuscript. Finally, the author(s) must seek permission and give credits for using an already published illustration when necessary. However, none of these are needed if the graphic is originally created by the author, but if it is a reproduced or an adapted illustration, the author must obtain permission from the copyright owner and include the necessary credit. One of the very important tools for designing illustrations is Creative Commons, a platform that provides a wide range of creative works which are available to the public for use and modification.

5.9. Conclusion/Future Perspectives

It has been observed that many reviews end abruptly with a short conclusion; however, a lot more can be included in this section in addition to what has been said in the major sections of the paper. Basically, the conclusion section of a review article should provide a summary of key findings from the main body of the manuscript. In this section, the author needs to revisit the critical points of the paper as well as highlight the accuracy, validity, and relevance of the inferences drawn in the article review. A good conclusion should highlight the relationship between the major points and the author's hypothesis as well as the relationship between the hypothesis and the broader discussion to demonstrate the significance of the review article in a larger context. In addition to giving a concise summary of the important findings that describe current knowledge, the conclusion must also offer a rationale for conducting future research [ 12 ]. Knowledge gaps should be identified, and themes should be logically developed in order to construct conceptual frameworks as well as present a way forward for future research in the field of study [ 11 ].

Furthermore, the author may have to justify the propositions made earlier in the manuscript, demonstrate how the paper extends past research works, and also suggest ways that the expounded theories can be empirically examined [ 3 ]. Unlike experimental studies which can only draw either a positive conclusion or ambiguous failure to reject the null hypothesis, four possible conclusions can be drawn from review articles [ 1 ]. First, the theory/hypothesis propounded may be correct after being proven from current evidence; second, the hypothesis may not be explicitly proven but is most probably the best guess. The third conclusion is that the currently available evidence does not permit a confident conclusion or a best guess, while the last conclusion is that the theory or hypothesis is false [ 1 ]. It is important not to present new information in the conclusion section which has link whatsoever with the rest of the manuscript. According to Harris et al. [ 90 ], the conclusions should, in essence, answer the question: if a reader were to remember one thing about the review, what would it be?

5.10. References

As it has been noted in different parts of this paper, authors must give the required credit to any work or source(s) of information that was included in the review article. This must include the in-text citations in the main body of the paper and the corresponding entries in the reference list. Ideally, this full bibliographical list is the last part of the review article, and it should contain all the books, book chapters, journal articles, reports, and other media, which were utilised in the manuscript. It has been noted that most journals and publishers have their own specific referencing styles which are all derived from the more popular styles such as the American Psychological Association (APA), Chicago, Harvard, Modern Language Association (MLA), and Vancouver styles. However, all these styles may be categorised into either the parenthetical or numerical referencing style. Although a few journals do not have strict referencing rules, it is the responsibility of the author to reference according to the style and instructions of the journal. Omissions and errors must be avoided at all costs, and this can be easily achieved by going over the references many times for due diligence [ 11 ]. According to Cronin et al. [ 12 ], a separate file for references can be created, and any work used in the manuscript can be added to this list immediately after being cited in the text [ 12 ]. In recent times, the emergence of various referencing management software applications such as Endnote, RefWorks, Mendeley, and Zotero has even made referencing easier. The majority of these software applications require little technical expertise, and many of them are free to use, while others may require a subscription. It is imperative, however, that even after using these software packages, the author must manually curate the references during the final draft, in order to avoid any errors, since these programs are not impervious to errors, particularly formatting errors.

6. Concluding Remarks

Writing a review article is a skill that needs to be learned; it is a rigorous but rewarding endeavour as it can provide a useful platform to project the emerging researcher or postgraduate student into the gratifying world of publishing. Thus, the reviewer must develop the ability to think critically, spot patterns in a large volume of information, and must be invested in writing without tiring. The prospective author must also be inspired and dedicated to the successful completion of the article while also ensuring that the review article is not just a mere list or summary of previous research. It is also important that the review process must be focused on the literature and not on the authors; thus, overt criticism of existing research and personal aspersions must be avoided at all costs. All ideas, sentences, words, and illustrations should be constructed in a way to avoid plagiarism; basically, this can be achieved by paraphrasing, summarising, and giving the necessary acknowledgments. Currently, there are many tools to track and detect plagiarism in manuscripts, ensuring that they fall within a reasonable similarity index (which is typically 15% or lower for most journals). Although the more popular of these tools, such as Turnitin and iThenticate, are subscription-based, there are many freely available web-based options as well. An ideal review article is supposed to motivate the research topic and describe its key concepts while delineating the boundaries of research. In this regard, experience-based information on how to methodologically develop acceptable and impactful review articles has been detailed in this paper. Furthermore, for a beginner, this guide has detailed “the why” and “the how” of authoring a good scientific review article. However, the information in this paper may as a whole or in parts be also applicable to other fields of research and to other writing endeavours such as writing literature review in theses, dissertations, and primary research articles. Finally, the intending authors must put all the basic rules of scientific writing and writing in general into cognizance. A comprehensive study of the articles cited within this paper and other related articles focused on scientific writing will further enhance the ability of the motivated beginner to deliver a good review article.

In the development of physical theories, thought experiments play a crucial role. Research on this topic began in 1976 and has continued to the present. This study aims to provide a more complete picture of the progress of thought experiments over the past two decades. To achieve this, this study employs bibliometric mapping methods. A total of 679 published papers were analyzed, including articles (504), conference papers (92), and book chapters (83). This data was retrieved from the Scopus database. The study's findings reveal that research and publications on thought experiments are highly valued and have received significant attention over the past eight years. According to the findings, 90% of the top 20 source titles contributing to thought experiments are from journals in the first and second quartiles (Q1 and Q2). This quartile ranking shows the quality and significant influence of a journal. The geographical distribution indicates that the United States contributes the most to thought experiments research, with 213 documents, 2592 citations, and 47 links. We also identified several prospective keywords that could be the focus of future research, including artificial intelligence, physics education, fiction, God, theology, productive imagination, technology, speculative design, and critical design. Therefore, this study provides a thorough picture of thought experiment research trends and future directions of potential topics that can be the focus of future researchers.

1 Introduction

Thought experiments (TEs) have a long history in science. Since Ernst Mach, the term TEs, a direct translation of the phrase Gedankenexperimente , has been widely discussed in the philosophy of science [ 18 ]. Thought and experiments are two components of TEs [ 4 , 18 , 29 ]. The thought element involves visualizing an imaginary world based on theory and experience, whereas the experimental aspect entails practical tasks in a physical laboratory, such as manipulating items and related variables. While some authors consider TEs to be mere arguments [ 24 ], others believe TEs are a form of fiction since their function is comparable to literary fiction in that both have a narrative framework by creating scenarios of occurrences from beginning to end [ 13 , 22 ]. However, unlike fiction, which frequently provides contradictory discourses, we believe that TEs should be logically and conceptually cohesive. TEs are structured imaginative actions based on the theory and experience of thought experimenters to achieve certain goals.

The contributions of TEs to the growth of scientific theories, particularly in physics, are essential. Physicists have employed TEs several times throughout history to either come up with new hypotheses or disprove previous ones. As the most representative examples, Newton used the TEs of cannonballs to support his hypothesis that the force of gravity is universal and the principal force of planetary motion, or Galileo used the TEs of free-falling bodies to disprove Aristotle's theory of gravity, which stated that the speed of falling objects is proportional to their weight. Galileo’s falling body, Newton's bucket and cannon, Maxwell's demon, and Schrodinger’s cat are just a few of the well-known TEs in physics [ 4 ]. These are only a few examples of the significant role TEs played in the development of scientific theories.

In the past 10 years, several works have studied TEs from the perspectives of history and philosophy of science [ 7 , 8 , 10 , 30 , 33 ]. Because most existing historical work on TEs focuses on individual TEs or individual accounts of TEs, reassessing the history of the philosophical debate on TEs becomes essential [ 33 ]. In the philosophy of science, historical debates regarding interactions between various philosophers or philosophical explanations across time in developed TEs are sometimes disregarded. Several studies have also used TEs as an imaginative tool in the classroom to teach science subjects. Velentzas and Halkia [ 37 ], for example, used TEs from Newton's Cannon to teach satellite physics. They then assert that TEs, as a teaching tool, can assist students in strengthening their syllogistic abilities and help them conceive scenarios beyond their everyday experience [ 37 ]. El Skaf and Palacios [ 12 ] have also systematically analyzed the epistemic role of TEs from Wheeler's demon and Geroch's engine, which gave rise to black hole thermodynamics. Recently, Bancong et al. [ 2 ] reported that physics teachers in Indonesia have a high awareness of the importance of TEs in learning physics, especially atomic theory and relativity, even though they lack skills in the pedagogic aspects of TEs. Therefore, Indonesian physics teachers also suggest using technology such as virtual reality to help visualize an imaginary world when performing TEs.

Although a number of studies on TEs from various perspectives have been conducted, no study has yet completely examined this field to look at the trend of this topic in recent years. Therefore, it becomes essential to conduct a bibliometric study of TEs over time based on authoritative databases like Scopus. Because of Scopus's comprehensive coverage of scholarly articles in the field of education [ 23 , 27 , 34 ], it was chosen as the database for this study. Scopus is also a popular resource for bibliometric research [ 23 , 28 ]. For this reason, we use data sources from the Scopus database to carry out the bibliometric method. Our study covers journal articles, conference papers, and book chapters from the last 20 years to provide a more complete view.

To highlight the significance of TEs research, we compare its growth to other scientific topics. While many scientific fields have seen growth over the past two decades, TEs research has also shown a unique and sustained increase in interest and publications. This trend contrasts sharply with the decline in research focus on traditional physics experiments [ 41 ]. Similarly, other topics in physics education, such as methodological issues, textbook analysis, and pre-service physics teachers, are also experiencing reduced research interest [ 25 ]. Additionally, the integration of TEs with emerging technologies, such as artificial intelligence, underscores their evolving relevance and potential for future research [ 21 ].

Therefore, this study aims to provide an up-to-date overview of trends in TEs research. The research questions in this study are as follows:

How is the growth of research output on the topic of TEs over the last 20 years?

Which source titles have contributed the most to the publication of papers on TEs in the last 20 years?

Who are the most prominent authors on the topic of TEs in the last 20 years?

Which countries have published the most articles on TEs over the past 20 years?

What are the most relevant keywords that can be found in the studies of TEs over the last 20 years?

2.1 Research design

This study aims to analyze the trends in TEs research over the past 20 years by using a bibliometric mapping method. To ensure a thorough analysis of recent trends and developments, this study focused on studies published between 2003 and 2022. This period was chosen because of significant advancements in research methodologies and bibliometric analysis tools in the early 2000s, as well as the consistent growth and comprehensive coverage of the Scopus database since that time. Bibliometric analysis is a well-known statistical method for examining and analyzing a large amount of scientific data on a certain topic [ 26 , 39 ]. Metrics studied in bibliometric research include annual publications, source titles, authors, institutions, nations, and keywords, covering data from primary, secondary, and tertiary journals over a specific time period. It should be noted that no ethical approval was required for this study as it did not involve humans or animals.

2.2 Data collection

In this study, data were gathered from the Scopus database ( https://www.scopus.com ). Scopus was chosen because it covers a wider range of documents than any other scientific database [ 23 , 28 , 35 ]. Scopus is the world's largest abstracting and indexing database, with 84 million records containing over 18.0 million open access items, including gold, hybrid gold, green, and bronze, as well as 10.9 million conference papers, 25.8 thousand active peer-reviewed journals, and over 7000 publishers [ 14 ]. In addition, Scopus covers a wider range of educational disciplines than other databases, such as the Web of Science (WoS) [ 23 , 27 , 34 ]. As a result, using the Scopus database enables researchers to shed light on areas that may not be covered in WoS.

Electronic data search and retrieval were conducted on February 25, 2023. Keyword search was set to include title, abstract, and keywords. The keyword search was set to include the title, abstract, and keywords. The combination of search strings, operators, and filters used in this study was TITLE-ABS-KEY ("Thought-experiments" AND "Science" OR "Physics"). Quotation marks were used to focus on documents containing this exact phrase, thus ensuring high relevance to the study's scope. The Scopus database retrieved 898 documents related to these keywords with full bibliographical information, including articles (67.04%), paper proceedings (10.13%), book chapters (10.02%), and other types of documents (12.81%). By using the Scopus filter, other types of publications (12.81%), including review articles, were excluded from the list of documents. The exclusion of review articles was intentional to focus on original research contributions that advance the field of TEs directly. Including reviews could confound the analysis as they often summarize existing research rather than introduce new findings. Therefore, concentrating on the three most prevalent types of documents—articles, conference papers, and book chapters—allowed for a clearer interpretation of trends and patterns in original research outputs over the specified period. Additionally, we limited the year of publication to studies published within the last 20 years (2003–2022) to ensure the relevance and currency of our analysis. After using a filtering process to eliminate papers that did not meet the inclusion and exclusion criteria, a total of 679 articles were identified for bibliometric analysis. These articles included 504 articles, 92 book chapters, and 83 conference papers.

2.3 Data analysis

The data analysis process began with acquiring the necessary raw data by downloading it from the Scopus database in either comma-separated value (CSV) or research information system (RIS) format. For data analysis and visualization, we used VOSviewer and Microsoft Excel. VOSviewer, a sophisticated mapping tool, was employed to create collaborative networks for various variables and keywords, while Microsoft Excel was used for descriptive analysis, such as determining the number of articles published each year and identifying the most prolific source titles.

The network graphs in this study were generated using VOSviewer, based on co-authorship, co-occurrence, and citation data from Scopus. The analysis type focused on the co-occurrence of keywords and co-authorship, with a full counting method. Keywords with a minimum of four occurrences were included. The visualization settings in VOSviewer were mainly default, with the attraction parameter set to 2 and the repulsion parameter set to 0. These settings ensured that the most relevant and frequently occurring terms were highlighted, providing a clear overview of research trends and collaborations in the field of TEs over the past 20 years.

In this study, we explored the most productive publishers, the most referenced articles, the most productive authors, the most productive nations, and author keyword occurrences across time. An analysis of co-authorship and co-occurrence was performed at this stage. The analysis of co-authorship provides insights into the interactions between authors. This methodology was also used for metrics related to countries. For country attribution, we included all the countries of all authors involved in each publication, not just the corresponding author. This method ensures that all co-authors' contributions are acknowledged and provides a comprehensive representation of the global distribution of research. Co-occurrence analysis was employed as a means of investigating current keywords and their interrelationships with other phrases associated with TEs. Within this particular framework, the term “node size” refers to the frequency at which a certain keyword appears in comparison to other words. Additionally, interconnected nodes are visually represented by lines known as connections. The link establishes a connection between two nodes, while the width of the link signifies the intensity or potency of the connection between the aforementioned nodes [ 36 , 39 ].

In the context of network map visualization, nodes that exhibit a high degree of association are categorized into clusters. The clustering of items was performed using the Louvain algorithm, a popular method for community detection in large networks due to its efficiency and accuracy in handling large datasets [ 36 , 39 ]. This algorithm was chosen for its ability to uncover modular structures within large networks, which is particularly useful for identifying distinct research themes and collaboration groups in bibliometric data. Subsequently, a distinct color code was assigned to each cluster, wherein nodes within the same cluster exhibit a high degree of homogeneity. Therefore, this bibliometric mapping approach enabled researchers to discern patterns and emerging areas of interest throughout the timeframe spanning from 2003 to 2022. Figure 1 shows the stages in the process of collecting and analyzing data in this study.

The steps in collecting and analyzing the data

3.1 Statistics analysis

In this analysis, we use statistical data to observe differences in the number of articles published each year. The goal is to determine whether the quantity of publications on the topic of TEs has increased or decreased annually. Figure 2 illustrates the number of papers published over the last 20 years (2003–2022). As we can see, there has been an increase in the interest and attention of researchers, scholars, and experts in researching TEs. The growth started in 2004 and continued until 2006. The number of papers published then fluctuated between 2006 and 2015. The increase started again in 2015 and continued until 2021. The number of publications increased significantly in 2021, with 69 articles published. This growth demonstrates that research and publications on TEs are in high demand and have garnered significant attention globally in the last eight years despite a reduction in 2022. Although studies in this area are still ongoing, these findings indicate an annual growth in the writing and publication of TEs on Scopus.

Number of articles published each year

Statistical data are also used to see the number of source titles that have made the greatest contributions to TEs during the last 20 years. A total of 679 papers have been published from various sources with different types of documents in the form of articles (504), conference papers (92), and book chapters (83). According to statistical data in the Scopus database, publication in journals is very significant in publishing research on the topic of TEs, while publication in proceedings and book chapters with the main scope of TEs is not very significant. Therefore, researchers, academics, and experts are advised to submit their articles focused on TEs to journals rather than proceedings and chapter books. Table 1 lists the top 20 sources of scientific research publications covering the topic of TEs from 2003 to 2022.

As seen in Table 1 , 90% of the source titles contributing to the TEs topic are journals, with only one publishing conference proceedings. Philosophical studies ranks first, with 17 documents published in the last 20 years. This is followed by the AIP Conference Proceedings with 15 documents. The American Journal of Physics, Science and Education, and Studies in History and Philosophy of Science Part A have published 11 documents each. Other source titles, such as Synthese (10), Foundations of Science (9), Physics Teacher (9), Journal for General Philosophy of Science (8), and Philosophy of Science (8), also contributed to publishing TEs topics. Minds and Machines and Physics Education each published seven documents. Erkenntnis, European Journal of Physics, Physics Essays, and Religions each published six documents, Acta Analytica published five documents, while Axiomathes, Boston Studies in the Philosophy of and History of Science, and European Journal for Philosophy of Science each published four documents.

3.2 Bibliometric analysis

3.2.1 contributions of authors.

Table 2 shows the 10 most prolific authors based on the total number of published articles from 2003 to 2022. As shown in this list, Stuart is the most significant author with 7 papers (51 citations), followed by Bancong from Universitas Muhammadiyah Makassar, Indonesia, with 5 papers (15 citations). Following Bancong, Fehige from the University of Toronto, Canada, has also published 5 articles. The majority of Fehige’s research focuses on TEs in the context of religion. In contrast to Fehige, Brown, also from the University of Toronto in Canada, has studied TEs through the lens of history and philosophy of science in several of his works (4 documents, 52 citations). Similarly, Buzzoni (3 documents, 15 citations) and El Skaf (3 documents, 29 citations) from Italy, discuss TEs from historical and philosophical perspectives of science. Meanwhile, Halkia and Velentzas from the University of Athens, Greece, have analyzed TEs thoroughly from an educational standpoint, with the number of documents being 4 and 86 citations.

3.2.2 Contributions of country

In the context of the leading countries, authors from 64 different countries/territories published a total of 679 documents. Table 3 lists the top 20 countries in terms of TE contributions based on the number of papers published. As shown, the United States contributes the most to TEs research, with 213 documents, 2592 citations, and 47 links. The number of papers is about three times that of the United Kingdom, which comes second (75 documents, 1016 citations, and 31 links). European countries continue to hold third to sixth place, with Germany publishing 50 documents with 634 citations, followed by Canada (43 documents, 410 citations, and 17 links), Italy (33 documents, 96 citations, 6 links), and the Netherlands (28 documents, 342 citations, and 12 links). This suggests that countries in America and Europe contribute the most to TEs. The Asian country that has contributed the most to TEs is China, with 18 documents, 286 citations, and 11 links, followed by India (14 documents), Japan (12 documents), and South Korea (12 documents), with 97, 111, and 27 citations, respectively. The three countries below these are European countries, with Austria having issued 10 documents related to TEs with a total of 135 citations, followed by Finland (9 documents, 31 citations) and Spain (9 documents, 47 citations).

3.2.3 Keywords

The results of a keyword analysis can be used in further investigation of the topic at hand. This study employs a minimum threshold of two occurrences of keywords in all research articles that were examined using VOSviewer. Figure 3 displays the 253 authors' keywords detected from 1990, which may be categorized into six distinct clusters. Cluster 1 is characterized by a red color, Cluster 2 by a green color, while Cluster 3 is distinguished by a blue color. In addition, Cluster 4 is characterized by a yellow color, Cluster 5 has a purple hue, and Cluster 6 is distinguished by a light blue shade. Each cluster is comprised of interconnected keywords that are visually represented by the same colors. It is important to note that the size and shape of the node are indicative of the frequency of its occurrences [ 36 , 39 ]. In other words, there is a positive correlation between the size of the node and the frequency of occurrences of these terms. Clustering is employed as a means to gain insights or a comprehensive understanding of bibliometric groupings, whereas image mapping serves the purpose of obtaining a holistic depiction of a bibliometric network.

Network visualization of TEs

Figure 3 shows Cluster 1 (red) with 68 items such as thought experiments, intuition, Science, Kant, Aristotle, Galileo, Platonism, personal identity, theology, fiction narrative, moral motivation, and neuroscience. Cluster 2 (green) consists of 57 categories, such as science fiction, philosophy of science, philosophy of physics, philosophical thought, epistemology, knowledge, scientific reasoning, experiments, models, and realism. Cluster 3 (blue) contains 41 items, such as consciousness, Maxwell's demon, Schrodinger's cat, quantum theory, entropy, uncertainty principle, quantum entanglement, quantum information, quantum physics, and Newton's bucket. Furthermore, cluster 4 (yellow) consists of 30 items: physics education, science education, visualization, special theory of relativity, history of physics, problem-solving, exploration, Einstein, relativity, and falsification. Cluster 5 (purple) consists of 29 items: imagination, ontology, physics, truth time, algorithm of discovery, artificial intelligence, ethics, nanotechnology, fiction, philosophy, and technology. Finally, cluster 6 (light blue) contains 16 categories, including popular science, fictionality, narrative, construction, sensation, a priori, story, Mach, memory, productive imagination, and schema.

Keywords in clusters 1 and 2 have a high number of occurrences and a high total link strength. The term thought experiment ranks first with 85 occurrences and a total link strength of 91. This is followed by the term thought experiment with 60 occurrences, a total link strength of 98, and several other keywords. The high number of occurrences and high total link strength indicate that scientific research publications on the topic of TEs in the 2003–2022 range indexed by Scopus have a strong and direct relationship with these keywords. Table 4 displays the ten keywords with the highest occurrence and overall link strength in the last 20 years on the topic of TEs.

VOSviewer, on the other hand, is also used to visualize the progress of keywords over a certain period. Figure 4 illustrates the overlay visualization of the TEs topic in the time range 2003 to 2022.

Overlay visualization of TEs

Figure 4 depicts the annual distribution of the number of articles containing keywords. The various colors represent the publication dates of the related papers where these keywords appear together. The data in Fig. 4 indicate that the most frequently used topics related to TEs from 2010 to 2014 were quantum theory, ethical naturalism, ethical naturalism, quantum mechanics, scientific discovery, and mental models. Then, from 2014 to 2018, keywords such as scientific reasoning, intuition, science education, computer simulation, history of science, and science fiction began to appear in the TEs topic. The hottest topics in TEs research are shown in yellow color, including fiction, artificial intelligence, God, theology, speculative design, critical design, and methods of case. These findings indicate that these keywords have gained popularity in recent years. It can be concluded that scholars have increasingly turned to research on the mentioned topics in recent years.

4 Discussion

The goal of this study is to use the bibliometric mapping method to examine the trend of studies on TEs during the last 20 years (2003–2022). According to the findings of the study, there has been an increase in the interest and attention of researchers, scholars, and professionals in studying TEs. Although research in this area is ongoing, these findings indicate an annual growth in the writing and publication of TEs on Scopus. This growth demonstrates that research and publications on TEs are in high demand and receive significant global attention.

Interestingly, 90% of the top 20 source titles contributing to TEs research are journals in the first quartile (Q1) and second quartile (Q2). Among these, 10 journals are in the highest quartile, Q1, and 8 journals are in Q2. The quartile level indicates that these journals have the highest quality and the greatest influence [ 39 , 40 ]. Furthermore, 7 source titles (Philosophical Studies, Synthese, Foundations of Science, Minds and Machines, Erkenntnis, Acta Analytica, and Axiomathes) that publish TEs topics focus on the field of philosophy. When studying TEs from a philosophical standpoint, researchers, scholars, and professionals have the option of submitting their articles to these journals. Alternatively, if TEs are studied from a historical perspective, journals such as Science and Education, Studies in History and Philosophy of Science Part A, Journal for General Philosophy of Science, Philosophy of Science, Boston Studies in the Philosophy and History of Science, and European Journal for Philosophy of Science are appropriate. Meanwhile, if TEs are studied from an educational perspective, Physics Teacher, Science and Education, Physics Education, American Journal of Physics, and European Journal of Physics are ideal choices for publishing articles. These journals regularly publish articles in physics education studies.

If we look at the authors who have made the greatest contributions to the topic of TEs in the previous 20 years (2003–2022), Stuart is the most significant author with 7 articles (51 citations). Stuart’s work focuses on the history and philosophy of TEs [ 31 , 32 , 33 ], with the first publication in 2014 in the journal Perspectives of Science. In contrast to Stuart, Bancong's work, which ranks second, investigates various TEs from an educational standpoint. His first work, published in 2018, examined TEs in high school physics textbooks [ 3 ], followed by an investigation of how students construct TEs collaboratively [ 4 ], and an identification of factors influencing TEs during problem-solving activities [ 5 ]. Following Bancong, Fehige from the University of Toronto, Canada, has also published 5 articles. Most of his work examines TEs in religious contexts, such as thought experiments, Christianity and science in novalis [ 15 ], thought experiments and theology [ 16 ], and the book of job as a thought experiment: on science, religion, and literature [ 17 ] which was published in the journal Religions in 2019. Brown examines TEs in several of his works in light of the history and philosophy of science [ 6 , 7 ], as do Buzzoni and El Skaf from Italy, who mostly discuss TEs in light of the history and philosophy of science [ 8 , 12 ]. Meanwhile, Halkia and Velentzas from the University of Athens, Greece, have discussed TEs from an educational perspective, such as using TEs from Newton's Cannon for teaching satellite physics [ 37 ] and using TEs from the theory of relativity for teaching relativity theories [ 38 ].

Over the past two decades, authors have examined TEs from diverse perspectives, including history, philosophy, education, and religion. This variety highlights a significant shift in the disciplinary landscape of TE research, which is historically rooted in the philosophy of science [ 18 , 24 ]. The true strength of TEs lies in their adaptability across disciplines, rather than in resolving philosophical disputes. Although TEs were traditionally centered on history and philosophy of science (HPS), recent trends show a growing application in education and technology, particularly in artificial intelligence and speculative design. This shift indicates that TEs have not lost their significance but have instead found new areas of relevance. In HPS, the focus has moved toward understanding the methodological and epistemological implications of TEs, confirming their essential role in scientific reasoning [ 7 , 30 ]. Additionally, in fields such as physics education, TEs are increasingly utilized to explore complex theoretical concepts and enhance educational methodologies [ 2 , 12 ].

Based on the most commonly used keywords in the last 20 years, research on TEs has mostly focused on understanding TEs from a philosophical perspective in the first five years (2003–2007). Thought experiments rethought and reperceived [ 19 ], on thought experiments: is there more to the argument? [ 24 ] and thought experiments [ 9 ] are a few examples. Then, over the next five years (2008–2012), many studies looked at how TEs contributed to physical theories, including the special theory of relativity and quantum theory. The keywords that emerged frequently during this period were quantum theory, scientific discovery, methodology, quantum mechanics, twin earths, falling bodies, and others. In the last ten years, TEs have been studied from various perspectives. For example, in 2013, Velentzas and Halkia [ 38 ] also used TEs as a didactic tool in teaching physics to upper-secondary students. Fehige, on the other hand, began to connect TEs to theology, with a specific focus on the interaction between Christianity and science [ 15 , 16 ]. There are also researchers who continue to study the existence of TEs from a philosophical point of view and claim that TEs are science fiction [ 1 , 20 ]. In recent years, TEs have become increasingly popular in education and have been linked to artificial intelligence. Artificial intelligence, physics education, productive imagination, technology, and speculative design are some of the keywords that appear frequently. This is not surprising because TEs, as experimental activities using mental models, are not easy for students to perform on their own [ 4 , 5 ]. Therefore, technology that can assist students in creating an imaginative world for constructing TEs is required.

Since no studies have charted the trends in TEs research so far, it is difficult to compare the research results obtained with those of others. Nevertheless, several studies that examine trends in physics education reveal that although research on experiments is declining in physics education, TEs are still important to physics teaching and learning [ 41 ]. Hallswoth et al. [ 21 ] have also used artificial intelligence technologies to support TEs in the field of wet biology research, which is dominated by experiments on microbial growth and survival. The use of artificial intelligence in learning is based on the growing interest in artificial intelligence methods in science, technology, and education [ 11 ]. Overall, our study contributes to a more comprehensive understanding of TEs research trends during the last 20 years. In addition, this research also contributes to providing an overview of several potential topics that can be the focus of future researchers, such as the use of artificial intelligence in TEs. By situating our findings within the broader context of previous studies, we provide a clearer picture of how TE research has evolved and where it is heading.

5 Conclusions

This study aims to present a more comprehensive understanding of the trend of studies on TEs during the last 20 years (2003–2022). Research on this topic began in 1976, and its progress has continued to the present. A total of 679 published papers from various sources, including articles (504), conference papers (92), and book chapters (83), were analyzed. The results of the study show that research and publications on TEs are of interest and have received a lot of attention during the last eight years. A significant increase occurred in 2021, with 69 published articles. According to the findings, 95% of the top 20 source titles contributing to TEs are from journals in the first and second quartiles (Q1 and Q2). This quartile ranking shows the quality and significant influence of a journal. The geographical distribution reveals that the United States contributes the most to TEs research, with 213 documents, 2592 citations, and 47 links. We also identified several prospective keywords that could be the focus of future research, including artificial intelligence, physics education, fiction, God, theology, productive imagination, technology, speculative design, and critical design. Therefore, this study contributes to providing a thorough picture of thought experiment research trends and future directions of potential topics that can be the focus of future researchers.

This research has several limitations. The exclusive source of publication data utilized in this study is the Scopus database, which is recognized as one of the most extensive databases in the field. However, it is worth noting that future research endeavors may consider including publication data from other prominent sources such as WoS and Google Scholar. Furthermore, the utilization of the search function in the TITLE-ABS-KEY field, specifically employing the terms "Thought-experiments" AND "Science" OR "Physics," was used for the purpose of data retrieval. However, it is important to acknowledge that this approach is not infallible, as there is a potential for some papers to be overlooked, making the process less than completely accurate. Despite its limitations, this research is often regarded as a pioneering contribution to the field of bibliometric studies on the subject of TEs during the past two decades.
