Definitions

A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).

An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources. Depending on your project or the assignment, your annotations may do one or more of the following.

For more help, see our handout on paraphrasing sources.

For more help, see our handouts on evaluating resources .

• Reflect : Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?

Your annotated bibliography may include some of these, all of these, or even others. If you're doing this for a class, you should get specific guidelines from your instructor.

Why should I write an annotated bibliography?

To learn about your topic : Writing an annotated bibliography is excellent preparation for a research project. Just collecting sources for a bibliography is useful, but when you have to write annotations for each source, you're forced to read each source more carefully. You begin to read more critically instead of just collecting information. At the professional level, annotated bibliographies allow you to see what has been done in the literature and where your own research or scholarship can fit. To help you formulate a thesis: Every good research paper is an argument. The purpose of research is to state and support a thesis. So, a very important part of research is developing a thesis that is debatable, interesting, and current. Writing an annotated bibliography can help you gain a good perspective on what is being said about your topic. By reading and responding to a variety of sources on a topic, you'll start to see what the issues are, what people are arguing about, and you'll then be able to develop your own point of view.

To help other researchers : Extensive and scholarly annotated bibliographies are sometimes published. They provide a comprehensive overview of everything important that has been and is being said about that topic. You may not ever get your annotated bibliography published, but as a researcher, you might want to look for one that has been published about your topic.

The format of an annotated bibliography can vary, so if you're doing one for a class, it's important to ask for specific guidelines.

The bibliographic information : Generally, though, the bibliographic information of the source (the title, author, publisher, date, etc.) is written in either MLA or APA format. For more help with formatting, see our MLA handout . For APA, go here: APA handout .

The annotations: The annotations for each source are written in paragraph form. The lengths of the annotations can vary significantly from a couple of sentences to a couple of pages. The length will depend on the purpose. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need more space.

You can focus your annotations for your own needs. A few sentences of general summary followed by several sentences of how you can fit the work into your larger paper or project can serve you well when you go to draft.

How to Write an Annotated Bibliography - APA Style (7th Edition)

What is an annotation, how is an annotation different from an abstract, what is an annotated bibliography, types of annotated bibliographies, descriptive or informative, analytical or critical, to get started.

An annotation is more than just a brief summary of an article, book, website, or other type of publication. An annotation should give enough information to make a reader decide whether to read the complete work. In other words, if the reader were exploring the same topic as you, is this material useful and if so, why?

While an abstract also summarizes an article, book, website, or other type of publication, it is purely descriptive. Although annotations can be descriptive, they also include distinctive features about an item. Annotations can be evaluative and critical as we will see when we look at the two major types of annotations.

An annotated bibliography is an organized list of sources (like a reference list). It differs from a straightforward bibliography in that each reference is followed by a paragraph length annotation, usually 100–200 words in length.

Depending on the assignment, an annotated bibliography might have different purposes:

• Provide a literature review on a particular subject
• Help to formulate a thesis on a subject
• Demonstrate the research you have performed on a particular subject
• Provide examples of major sources of information available on a topic
• Describe items that other researchers may find of interest on a topic

There are two major types of annotated bibliographies:

A descriptive or informative annotated bibliography describes or summarizes a source as does an abstract; it describes why the source is useful for researching a particular topic or question and its distinctive features. In addition, it describes the author's main arguments and conclusions without evaluating what the author says or concludes.

For example:

McKinnon, A. (2019). Lessons learned in year one of business.  Journal of Legal Nurse Consulting ,  30 (4), 26–28. This article describes some of the difficulties many nurses experience when transitioning from nursing to a legal nurse consulting business. Pointing out issues of work-life balance, as well as the differences of working for someone else versus working for yourself, the author offers their personal experience as a learning tool. The process of becoming an entrepreneur is not often discussed in relation to nursing, and rarely delves into only the first year of starting a new business. Time management, maintaining an existing job, decision-making, and knowing yourself in order to market yourself are discussed with some detail. The author goes on to describe how important both the nursing professional community will be to a new business, and the importance of mentorship as both the mentee and mentor in individual success that can be found through professional connections. The article’s focus on practical advice for nurses seeking to start their own business does not detract from the advice about universal struggles of entrepreneurship makes this an article of interest to a wide-ranging audience.

An analytical or critical annotation not only summarizes the material, it analyzes what is being said. It examines the strengths and weaknesses of what is presented as well as describing the applicability of the author's conclusions to the research being conducted.

Analytical or critical annotations will most likely be required when writing for a college-level course.

McKinnon, A. (2019). Lessons learned in year one of business.  Journal of Legal Nurse Consulting ,  30 (4), 26–28. This article describes some of the difficulty many nurses experience when transitioning from nursing to a nurse consulting business. While the article focuses on issues of work-life balance, the differences of working for someone else versus working for yourself, marketing, and other business issues the author’s offer of only their personal experience is brief with few or no alternative solutions provided. There is no mention throughout the article of making use of other research about starting a new business and being successful. While relying on the anecdotal advice for their list of issues, the author does reference other business resources such as the Small Business Administration to help with business planning and professional organizations that can help with mentorships. The article is a good resource for those wanting to start their own legal nurse consulting business, a good first advice article even. However, entrepreneurs should also use more business research studies focused on starting a new business, with strategies against known or expected pitfalls and issues new businesses face, and for help on topics the author did not touch in this abbreviated list of lessons learned.

Now you are ready to begin writing your own annotated bibliography.

• Choose your sources - Before writing your annotated bibliography, you must choose your sources. This involves doing research much like for any other project. Locate records to materials that may apply to your topic.
• Review the items - Then review the actual items and choose those that provide a wide variety of perspectives on your topic. Article abstracts are helpful in this process.
• The purpose of the work
• A summary of its content
• Information about the author(s)
• For what type of audience the work is written
• Its relevance to the topic
• Any special or unique features about the material
• Research methodology
• The strengths, weaknesses or biases in the material

Annotated bibliographies may be arranged alphabetically or chronologically, check with your instructor to see what he or she prefers.

Please see the  APA Examples page  for more information on citing in APA style.

How to Prepare an Annotated Bibliography: The Annotated Bibliography

• The Annotated Bibliography
• Fair Use of this Guide

Explanation, Process, Directions, and Examples

What is an annotated bibliography.

An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited.

Annotations vs. Abstracts

Abstracts are the purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes. Annotations are descriptive and critical; they may describe the author's point of view, authority, or clarity and appropriateness of expression.

The Process

Creating an annotated bibliography calls for the application of a variety of intellectual skills: concise exposition, succinct analysis, and informed library research.

First, locate and record citations to books, periodicals, and documents that may contain useful information and ideas on your topic. Briefly examine and review the actual items. Then choose those works that provide a variety of perspectives on your topic.

Cite the book, article, or document using the appropriate style.

Write a concise annotation that summarizes the central theme and scope of the book or article. Include one or more sentences that (a) evaluate the authority or background of the author, (b) comment on the intended audience, (c) compare or contrast this work with another you have cited, or (d) explain how this work illuminates your bibliography topic.

Critically Appraising the Book, Article, or Document

For guidance in critically appraising and analyzing the sources for your bibliography, see How to Critically Analyze Information Sources . For information on the author's background and views, ask at the reference desk for help finding appropriate biographical reference materials and book review sources.

Choosing the Correct Citation Style

Check with your instructor to find out which style is preferred for your class. Online citation guides for both the Modern Language Association (MLA) and the American Psychological Association (APA) styles are linked from the Library's Citation Management page .

Sample Annotated Bibliography Entries

The following example uses APA style ( Publication Manual of the American Psychological Association , 7th edition, 2019) for the journal citation:

Waite, L., Goldschneider, F., & Witsberger, C. (1986). Nonfamily living and the erosion of traditional family orientations among young adults. American Sociological Review, 51 (4), 541-554. The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.

This example uses MLA style ( MLA Handbook , 9th edition, 2021) for the journal citation. For additional annotation guidance from MLA, see 5.132: Annotated Bibliographies .

Waite, Linda J., et al. "Nonfamily Living and the Erosion of Traditional Family Orientations Among Young Adults." American Sociological Review, vol. 51, no. 4, 1986, pp. 541-554. The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.

Annotated Bibliography Format & Examples

A complete guide to the mla & apa annotated bibliography.

If you’ve just received an assignment that requires an MLA or APA annotated bibliography, you may be wondering where to start. This guide will help answer all of your questions and includes step-by-step instructions on how to do an annotated bibliography in MLA style, as well as an APA annotated bibliography. You will also find sample annotated bibliographies, real-life examples, and opportunities to practice what you have learned.

The MLA ( Modern Language Association ) and APA (American Psychological Association) are not associated with this guide. All of the information provided here, however, offers direction for students and researchers who use these citation styles in their work.

The structures and annotated bibliography templates on this page were created by the in-house librarians at EasyBib.com.

If you’re simply looking for an example of an annotated bibliography (both in MLA format and APA format), scroll down toward the bottom of the page. We’ve included links to visuals for those of you who need help with the structure and styling of an annotated bibliography. If you’re looking for a variety of annotated bibliography topics, and you’re truly searching for the answer to, “What is an annotated bibliography?” then continue reading!

Here’s a run-through of everything this page includes:

A bibliography is a complete list of the sources that were used to complete a research paper or project.

Depending on the style guide you follow, you may also see this called a Works Cited (also called an MLA bibliography) or Reference List (APA format). Each listed source, or citation , shares information about the author, title, publishing year, and other details that serve to credit the original authors whose work informed your research. These details also help other students and researchers find and read the source materials.

When your research is related to a scholastic assignment, you should always verify your instructor’s requirements for the types and number of sources to include, as well as the style you should adhere to when formatting your paper and bibliography.

An MLA annotated bibliography and an APA format annotated bibliography are bibliographies that include a concise explanation, or annotation , of each listed source. Depending on the assignment, this annotation may be solely descriptive, or analytical.

An abstract and annotation should not be confused; they differ in both their substance as well as their placement in a paper.

Annotations: 

• Usually found in bibliographies at the end of a paper
• Are subjective
• Purpose is to summarize and evaluate . It should briefly communicate the work’s main point, but also discuss the background of the author or study, and the strengths/weaknesses of the work.

Abstracts: 

• Usually found in journal databases or the beginning of a paper
• Are objective
• Purpose is to summarize . It should provide a short overview of the article and communicate the main points and themes.

If you would like to learn more , this link further explores the difference between an abstract and an annotation.

This resource provides additional information on how to write a bibliography with annotations in other formats. You can also take advantage of the plagiarism checker and bibliography tools that come with EasyBib Plus to help you create your reference lists.

Before you learn how to make an annotated bibliography, you may be wondering why you need to.

Sometimes instructors want you to create and include annotations in your bibliography, either as part of an assignment or as an assignment unto itself. Understanding the purpose of this approach to your reference list can help to ensure that you gain all of the benefits that the annotated bibliography process provides.

As a student, this method will help you develop or hone your research skills, providing you with practice not only in locating sources but also in analyzing and evaluating them for relevance and quality.

Your instructor will gain insight into your research abilities, as well, allowing them to assess your work more thoroughly. If you plan to publish your research, this comprehensive approach to detailing your sources will provide readers and other researchers with a substantial directory of resources to evaluate for their own work.

Whether you’re publishing or submitting your annotated bibliography, make sure your spelling and wording is correct! If you need to brush up on any parts of speech topics, check out our interjection , determiner , and adverb pages!

Step 1: Analyze your sources 

Each annotation should be a summarization or analysis of your source. If you have been tasked with writing annotations as part of a research paper or project, begin to create both the citation and notes on the source while you identify and analyze your sources.

Not only will this approach help you to hone your research skills and identify sources that are relevant and useful for your topic, but you will also save time. When done in this manner, both your citations and annotations will be nearly complete before you begin to write the body of your paper.

Analyzing your potential sources requires a two-pronged approach that first evaluates the author, publication, and date, and then examines the content.

When conducting your initial assessment of the source, consider some of the following questions to guide your appraisal:

• What qualifies the author to write on this subject?
• Is the author affiliated with a reputable institution in this field?
• Is the author credentialed or otherwise considered an expert in this field?
• Is this source current?
• Is this the most recent edition?
• Is the publisher reputable?
• Is the journal reputable?

Once your primary evaluation is complete, you will move on the assessing the content itself. Consider some of these elements as you review each source:

• Who is the intended audience?
• Is the author presenting her opinion or interpretation as the truth, or stating facts?
• What supporting evidence does the author provide?
• Did the author perform the research, or curate and present the research of others?
• If the author used the research of others, are the sources the author cites credible?
• Are there errors or omissions of fact?
• Is the author writing objectively and without bias?

Also, consider the value each source provides to you:

• Is the information helpful for your particular assignment?
• Does it help answer your research question(s)?
• Is this source different from your other sources, or does it repeat information you already have?
• Is the source providing you with a different perspective on your topic, or changing your beliefs or thinking about your subject?

To make it easier for you to create your reference page, write your notes in the format you will be using when you construct this part of the assignment (for instance, as short phrases or complete sentences). Once you have identified all of the sources you wish to include, you will merely need to insert what you have already written on the page and write your citation, which is explained in the next section.

Click here for additional information and a supplementary annotated bibliography sample. For an MLA bibliography example (with annotations),  check out our visual example of an MLA annotated bibliography .

An annotated bibliography entry may be written either as short phrases or complete sentences. Your instructor will advise you of which approach you are required to take.

Annotations should include either:

• The main points from the source, as well as the topics covered, the approach used, and any findings.
• Or your critical evaluation.
• A standard annotation is approximately one paragraph.
• Take care not to include any unnecessary details, as the goal is to summarize each source as succinctly as possible and, in some cases, evaluate them.
• Your field of study or instructor will determine what format your annotated bibliography will use. In this guide, you’ll find examples of an MLA and an APA annotated bibliography.

Here is an annotated bibliography example MLA annotation for the book The Elements of Eloquence: Secrets of the Perfect Turn of Phrase by UK author and blogger Mark Forsyth:

The author, Mark Forsyth, examines the rhetorical devices used in the English language, analyzing the patterns and formats that create memorable quotes. He traces the history of rhetoric to the Ancient Greeks, and provides an abridged timeline, following their use and evolution through to modern day. The author also explores the broader subject of persuasion and maps out the role that the figures of rhetoric play in it. In all, he examines over thirty devices, dissecting notable passages and phrases from pop music, the plays of William Shakespeare, the Bible, and more to explore the figures of rhetoric at work within each of them. Thorough definitions accompany this examination of structure to demonstrate how these formulas have been used to generate famously memorable expressions as well as how to reproduce their effects.

Notice how the annotated bibliography MLA entry above is descriptive enough so the reader has an idea of what the source is about with just a single paragraph. For more information on annotations, check out this informative site . If you’re looking to strengthen your writing in general, reading these grammar guides could be a good start.

For guidance on creating entries in MLA format , APA format , and more styles , check out the EasyBib library of resources or try the EasyBib annotation tool—we talk about it below!

Step 3a: MLA annotated bibliography format

The MLA Style Center and the current edition of the MLA Handbook provide the following guidance for formatting an MLA annotated bibliography:

• Title your reference page as “Annotated Bibliography” or “Annotated List of Works Cited.”
• Place each annotation after its reference.
• Annotations should typically not exceed a single paragraph.
• Annotations should be indented one inch from the start of your citation.
• Double-space all text on the page.
• 1-inch margins around the page.

Sources in an annotated bibliography can be organized alphabetically by the first word in each reference (as with a normal Works Cited page), by publication date, or by subject.

For a visual example of an annotated bibliography, as well as specific annotation examples, visit the MLA annotated bibliography guide .

If you are required to share your references in a manner other than in MLA bibliography format, the EasyBib style guides can help you with many common styles. While you’re at it, check out their conjunction , preposition , and pronoun pages to help keep your paper in mint condition!

Step 3b: APA annotated bibliography format

The American Psychological Association states that your instructor should set the guidelines for your annotated bibliography, but asks that the bibliography be formatted according to their standard reference page rules (see Section 9.51 of the Publication Manual ). If your teacher has requested an APA formatted annotated bibliography, first ask them for guidelines. Otherwise, here are some quick rules for you to follow:

• Double space all text on the page.  
• Title your page “Annotated Bibliogra phy”. Bold and center the title.  
• Organize references alphabetically by the first word of each reference.  
• Only the first line of a ref erence is flush with the left margin. Any other lines after the first line should be indented ½ inch from the left.  
• Add annotations on the next line after their paired reference.   
• Fully indent annotations by a ½ inch from the left.  
• Keep annotations short. No more than one paragraph.  

For examples of a  properly formatted APA annotation, visit this guide on APA annotated bibliographies .  

In comparison to the sample annotated bibliography MLA, the APA sample formats its page elements and references differently.

Students and researchers who type their research notes can save time by using an annotated bibliography template in MLA format while reviewing and analyzing sources. By adding the relevant information into a pre-formatted template, you’ll create a resource that helps you when you begin writing your paper in addition to saving time by completing your references and summaries alongside your research.

Students who prefer to take notes by hand can employ a modified version of this approach, with an additional step required to transfer your handwritten and formatted references from your notebook to populate your reference page.

Bibliography Template for MLA

To create an annotated bibliography MLA template, copy the following details into the program in which you will take notes or hand write it on the top margin of a page in your notebook. For each source, use this template to guide you as you identify the necessary details and insert them into your notes:

• Author (Last name, First name).
• Title of source.
• Title of the container ,
• Other contributors (names and roles),
• Publication Date,
• Location of the source (such as URL or page range).
• Summary or Analysis.

The MLA 9 model for MLA works cited entries offers a single format for all source type, and a great deal of flexibility to include the information most relevant to your topic and omit that which isn’t.

Hopefully our visual annotated bibliography example in MLA above has helped. If you still have lingering questions, visit the MLA Style Center online ( linked here ). Also, here’s a guide if you’re looking for more on the related topic of MLA in-text & parenthetical citations .

Bibliography Template for APA

Students and researchers who are still asking themselves how to piece together an annotated bibliography, or still questioning what is an annotated bibliography, could probably benefit from a template, similar to the one above. This one, however, is for those of you who are tasked with creating an annotated bibliography in the style created by the American Psychological Association.

The tricky thing about this specific style though, is that every reference is styled differently. Books, websites, journal articles, newspaper articles, and many others each have their own reference structure.

For most sources though, you should look for the following, basic information:

• Type of source
• Author (last name, first name)
• Title of source/article/web page, etc.
• Title of where source was found (e.g., database name, website name, etc.)
• Other contributors (names and roles)
• Location of the source (such as URL, DOI, or page range)
• Summary or Analysis

We understand it can get tricky, and it’s very different from the Modern Language Association’s structure for references. Take a moment to either use the other handy guides on EasyBib.com or use our automatic generator to form your references in just a few clicks. Our tools help take the pain away from having to rack your brain to form references properly. Capitals, lowercase letters, italics, quotation marks, punctuation in the appropriate places, it can all be quite overwhelming. Do yourself a favor, and use the EasyBib automatic citation generator.

Even though there are a lot of different variations, here’s a commonly used structure for sources:

Author’s Last Name, First initial, Middle initial. (Year the source was published). Title of the source . Retrieved from (insert the website address here)

Underneath the reference, include your summary or analysis paragraph.

Hopefully, this page helped answer all of your “What is an annotated bibliography?” questions. If you’re seeking out an annotated bibliography generator, follow the steps above the annotated bibliography examples.

If you are creating a bibliography in MLA format, the EasyBib MLA bibliography generator can help save you time formatting your citations and annotations correctly. You can create entries for websites, books, videos, databases, dictionary articles, and many other types of sources.

In addition to forming the citations, you can also enter your annotation text to produce the complete entry for each source. The process for this is simple. You can follow along below to practice creating one:

• First, select your source type from among the 50+ available options. For this example, we will use the acting career of Keanu Reeves as our research topic and use the movie Point Break from 1991 as our first source. To cite this film, you would select the option for “Film/Online Video.” As you follow along, pick the option that is suitable for your source if you are using a different example.
• Enter the title of your source or, if you are citing a website, you may enter the URL. (Now would be a great time to peek at how to cite websites in MLA ). After you enter the title or URL for your reference, the EasyBib citation tool will scan for titles that match it and provide you with a list of results. Select “Cite this” next to the listing that matches your source.
• You will see a citation form. This gives you the option to add additional relevant or necessary information. For our sample topic, we will specifically cite Keanu Reeves as the performer and Kathryn Bigelow as the director.
• After entering any additional details, you have the option to expand your entry and include an annotation. To do so, select “Add annotation” at the bottom of the page, and a text box will open up.

Then, type your summary or analysis into the text box. If you took notes during the research stage using the format of your paper, this might be as simple as copying and pasting your already written summary or critique. Once you have entered all of the necessary information, select “Create citation” to generate the complete entry. You can then copy and paste this into your MLA bibliography.

Here’s what it’ll look like:

Point Break . Directed by Kathryn Bigelow, performance by Keanu Reeves, 20th Century Fox, 1991.

Reeves’ role as rookie FBI Agent Johnny Utah in Point Break marks the turning point in his Hollywood film career. While he’d risen to fame due to the success of the Bill and Ted franchise, his status today as an action star began when Point Break provided him with the material to establish himself as capable of portraying more than the lovable but unserious characters of his previous starring roles. In a parallel arc, director Kathryn Bigelow’s career also sees a shift beginning with Point Break , establishing her within the traditional action genre as a serious director capable of creating high-action and visually memorable films. While Point Break leaves plenty to be desired in terms of dialogue, it afforded Bigelow and Reeves the opportunities to showcase themselves and their talent in new ways that still echo in their work today.

An annotated bibliography is a list containing complete information of sources, such as journals, books, and reports, cited in the text. In addition, it provides a brief description of each source in about 100–150 words. The annotation can explain the topics covered in the source or evaluate the source. The main objective of giving the annotation is to provide the reader the importance, accuracy, and value of the source.

An example of an annotated bibliography in APA style is given below.

Lim, L. (2014). Ideology, rationality and reproduction in education: A critical discourse analysis. Discourse: Studies in the Cultural Politics of Education, 35 (1), 61–76. https://doi:10.1080/01596306.2012.739467

Lim (2014) focuses on issues of power and ideology dominant in curricular discourses of rationality to study a discourse analysis of the goals of one of the most important curricula in the teaching of thinking. He proves that political and class commitments are reproduced in the forms of thinking that are valued in societies. Through his research, Lim asserts that such curricula engage in making our understanding of what thinking and rationality are. It must facilitate the social reproduction of a specific proportion of the middle class.

If you want to evaluate or provide a description of a source you are citing, you can create an annotated bibliography. Write your annotation in 100–150 words and add it below the source for which you are providing your annotation. Remember, your annotation should provide the reader the importance, accuracy, and value of the source. Below are the guidelines and rules to be followed while writing an annotated bibliography for APA style:

Order your reference entries in alphabetical order, similar to how you would order entries in the reference list.

If you want to add an annotation to an entry, add it as a fresh paragraph below the reference entry. The annotation is indented 0.5 inches from the left margin. However, the first line of the annotation is not indented.

To format the annotated bibliography, follow the recommendations given below:

Set the left, right, top, and bottom margins to 1 inch.

Give double-line spacing.

Title the page “Annotated Bibliography.” Set it in bold.

The title should be aligned to the center of the page.

Annotated Bibliographies

What this handout is about.

This handout will explain why annotated bibliographies are useful for researchers, provide an explanation of what constitutes an annotation, describe various types of annotations and styles for writing them, and offer multiple examples of annotated bibliographies in the MLA, APA, and CBE/CSE styles of citation.

Introduction

Welcome to the wonderful world of annotated bibliographies! You’re probably already familiar with the need to provide bibliographies, reference pages, and works cited lists to credit your sources when you do a research paper. An annotated bibliography includes descriptions and explanations of your listed sources beyond the basic citation information you usually provide.

Why do an annotated bibliography?

One of the reasons behind citing sources and compiling a general bibliography is so that you can prove you have done some valid research to back up your argument and claims. Readers can refer to a citation in your bibliography and then go look up the material themselves. When inspired by your text or your argument, interested researchers can access your resources. They may wish to double check a claim or interpretation you’ve made, or they may simply wish to continue researching according to their interests. But think about it: even though a bibliography provides a list of research sources of all types that includes publishing information, how much does that really tell a researcher or reader about the sources themselves?

An annotated bibliography provides specific information about each source you have used. As a researcher, you have become an expert on your topic: you have the ability to explain the content of your sources, assess their usefulness, and share this information with others who may be less familiar with them. Think of your paper as part of a conversation with people interested in the same things you are; the annotated bibliography allows you to tell readers what to check out, what might be worth checking out in some situations, and what might not be worth spending the time on. It’s kind of like providing a list of good movies for your classmates to watch and then going over the list with them, telling them why this movie is better than that one or why one student in your class might like a particular movie better than another student would. You want to give your audience enough information to understand basically what the movies are about and to make an informed decision about where to spend their money based on their interests.

What does an annotated bibliography do?

A good annotated bibliography:

• encourages you to think critically about the content of the works you are using, their place within a field of study, and their relation to your own research and ideas.
• proves you have read and understand your sources.
• establishes your work as a valid source and you as a competent researcher.
• situates your study and topic in a continuing professional conversation.
• provides a way for others to decide whether a source will be helpful to their research if they read it.
• could help interested researchers determine whether they are interested in a topic by providing background information and an idea of the kind of work going on in a field.

What elements might an annotation include?

• Bibliography according to the appropriate citation style (MLA, APA, CBE/CSE, etc.).
• Explanation of main points and/or purpose of the work—basically, its thesis—which shows among other things that you have read and thoroughly understand the source.
• Verification or critique of the authority or qualifications of the author.
• Comments on the worth, effectiveness, and usefulness of the work in terms of both the topic being researched and/or your own research project.
• The point of view or perspective from which the work was written. For instance, you may note whether the author seemed to have particular biases or was trying to reach a particular audience.
• Relevant links to other work done in the area, like related sources, possibly including a comparison with some of those already on your list. You may want to establish connections to other aspects of the same argument or opposing views.

The first four elements above are usually a necessary part of the annotated bibliography. Points 5 and 6 may involve a little more analysis of the source, but you may include them in other kinds of annotations besides evaluative ones. Depending on the type of annotation you use, which this handout will address in the next section, there may be additional kinds of information that you will need to include.

For more extensive research papers (probably ten pages or more), you often see resource materials grouped into sub-headed sections based on content, but this probably will not be necessary for the kinds of assignments you’ll be working on. For longer papers, ask your instructor about their preferences concerning annotated bibliographies.

Did you know that annotations have categories and styles?

Decisions, decisions.

As you go through this handout, you’ll see that, before you start, you’ll need to make several decisions about your annotations: citation format, type of annotation, and writing style for the annotation.

First of all, you’ll need to decide which kind of citation format is appropriate to the paper and its sources, for instance, MLA or APA. This may influence the format of the annotations and bibliography. Typically, bibliographies should be double-spaced and use normal margins (you may want to check with your instructor, since they may have a different style they want you to follow).

MLA (Modern Language Association)

See the UNC Libraries citation tutorial for basic MLA bibliography formatting and rules.

• MLA documentation is generally used for disciplines in the humanities, such as English, languages, film, and cultural studies or other theoretical studies. These annotations are often summary or analytical annotations.
• Title your annotated bibliography “Annotated Bibliography” or “Annotated List of Works Cited.”
• Following MLA format, use a hanging indent for your bibliographic information. This means the first line is not indented and all the other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• Begin your annotation immediately after the bibliographic information of the source ends; don’t skip a line down unless you have been told to do so by your instructor.

APA (American Psychological Association)

See the UNC Libraries citation tutorial for basic APA bibliography formatting and rules.

• Natural and social sciences, such as psychology, nursing, sociology, and social work, use APA documentation. It is also used in economics, business, and criminology. These annotations are often succinct summaries.
• Annotated bibliographies for APA format do not require a special title. Use the usual “References” designation.
• Like MLA, APA uses a hanging indent: the first line is set flush with the left margin, and all other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line.
• The entire annotation is indented an additional two spaces, so that means each of its lines will be six spaces from the margin (if your instructor has said that it’s okay to tab over instead of using the four spaces rule, indent the annotation two more spaces in from that point).

CBE (Council of Biology Editors)/CSE (Council of Science Editors)

See the UNC Libraries citation tutorial for basic CBE/CSE bibliography formatting and rules.

• CBE/CSE documentation is used by the plant sciences, zoology, microbiology, and many of the medical sciences.
• Annotated bibliographies for CBE/CSE format do not require a special title. Use the usual “References,” “Cited References,” or “Literature Cited,” and set it flush with the left margin.
• Bibliographies for CSE in general are in a slightly smaller font than the rest of the paper.
• When using the name-year system, as in MLA and APA, the first line of each entry is set flush with the left margin, and all subsequent lines, including the annotation, are indented three or four spaces.
• When using the citation-sequence method, each entry begins two spaces after the number, and every line, including the annotation, will be indented to match the beginning of the entry, or may be slightly further indented, as in the case of journals.
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line. The entire annotation follows the indentation of the bibliographic entry, whether it’s N-Y or C-S format.
• Annotations in CBE/CSE are generally a smaller font size than the rest of the bibliographic information.

After choosing a documentation format, you’ll choose from a variety of annotation categories presented in the following section. Each type of annotation highlights a particular approach to presenting a source to a reader. For instance, an annotation could provide a summary of the source only, or it could also provide some additional evaluation of that material.

In addition to making choices related to the content of the annotation, you’ll also need to choose a style of writing—for instance, telescopic versus paragraph form. Your writing style isn’t dictated by the content of your annotation. Writing style simply refers to the way you’ve chosen to convey written information. A discussion of writing style follows the section on annotation types.

Types of annotations

As you now know, one annotation does not fit all purposes! There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Your assignments will usually make it clear which citation format you need to use, but they may not always specify which type of annotation to employ. In that case, you’ll either need to pick your instructor’s brain a little to see what they want or use clue words from the assignment itself to make a decision. For instance, the assignment may tell you that your annotative bibliography should give evidence proving an analytical understanding of the sources you’ve used. The word analytical clues you in to the idea that you must evaluate the sources you’re working with and provide some kind of critique.

Summary annotations

There are two kinds of summarizing annotations, informative and indicative.

Summarizing annotations in general have a couple of defining features:

• They sum up the content of the source, as a book report might.
• They give an overview of the arguments and proofs/evidence addressed in the work and note the resulting conclusion.
• They do not judge the work they are discussing. Leave that to the critical/evaluative annotations.
• When appropriate, they describe the author’s methodology or approach to material. For instance, you might mention if the source is an ethnography or if the author employs a particular kind of theory.

Informative annotation

Informative annotations sometimes read like straight summaries of the source material, but they often spend a little more time summarizing relevant information about the author or the work itself.

Indicative annotation

Indicative annotation is the second type of summary annotation, but it does not attempt to include actual information from the argument itself. Instead, it gives general information about what kinds of questions or issues are addressed by the work. This sometimes includes the use of chapter titles.

Critical/evaluative

Evaluative annotations don’t just summarize. In addition to tackling the points addressed in summary annotations, evaluative annotations:

• evaluate the source or author critically (biases, lack of evidence, objective, etc.).
• show how the work may or may not be useful for a particular field of study or audience.
• explain how researching this material assisted your own project.

Combination

An annotated bibliography may combine elements of all the types. In fact, most of them fall into this category: a little summarizing and describing, a little evaluation.

Writing style

Ok, next! So what does it mean to use different writing styles as opposed to different kinds of content? Content is what belongs in the annotation, and style is the way you write it up. First, choose which content type you need to compose, and then choose the style you’re going to use to write it

This kind of annotated bibliography is a study in succinctness. It uses a minimalist treatment of both information and sentence structure, without sacrificing clarity. Warning: this kind of writing can be harder than you might think.

Don’t skimp on this kind of annotated bibliography. If your instructor has asked for paragraph form, it likely means that you’ll need to include several elements in the annotation, or that they expect a more in-depth description or evaluation, for instance. Make sure to provide a full paragraph of discussion for each work.

As you can see now, bibliographies and annotations are really a series of organized steps. They require meticulous attention, but in the end, you’ve got an entire testimony to all the research and work you’ve done. At the end of this handout you’ll find examples of informative, indicative, evaluative, combination, telescopic, and paragraph annotated bibliography entries in MLA, APA, and CBE formats. Use these examples as your guide to creating an annotated bibliography that makes you look like the expert you are!
