The Annotated Bibliography

What is an AB?

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.

  • Summarize: Some annotations merely summarize the source. What are the main arguments? What is the point of this book or article? What topics are covered? If someone asked what this article/book is about, what would you say? The length of your annotations will determine how detailed your summary is.

    For more help, see our handout on paraphrasing sources.

  • Assess: After summarizing a source, it may be helpful to evaluate it. Is it a useful source? How does it compare with other sources in your bibliography? Is the information reliable? Is this source biased or objective? What is the goal of this source?

    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.

Tips on Formatting

  • Each annotation should be one paragraph, between three to six sentences long (about 150- 200 words).
  • Start with the same format as a regular Works Cited list.
  • All lines should be double-spaced. Do not add an extra line between the citations.
  • If your list of citations is especially long, you can organize it by topic.
  • Try to be objective, and give explanations if you state any opinions.
  • Use the third person (e.g., he, she, the author) instead of the first person (e.g., I, my, me)
