What is an annotated bibliography?
An annotated bibliography includes a summary and evaluation of each of the sources you used for researching your topic. Your annotations should do the following for each of your sources:

For more help, see the Evaluating Your Sources tab in this guide.
How long should the annotations be?
Generally, annotations are one paragraph, with a goal of concise and explicative annotations. Usually one or two sentences summarizing or describing content, one or two sentences providing an evaluation, and a final sentence or two on your reflection is sufficient.
What is the format?
For the bibliographic information, cite your sources according to the format required. Whichever format you use, be consistent! See the Attribution and Zotero tab in this guide for information.
The annotations for each source are written in paragraph form. The paragraph should contain a statement of the work's major thesis, from which the rest of the sentences can develop.
How should it be organized?
Usually annotated bibliographies are arranged alphabetically although sometimes they are organized chronologically, by format (books, journals, etc...), or by topic.
Why write an annotated bibliography?
To learn about your topic: Writing an annotated bibliography is excellent preparation for a research project. 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.
To help you formulate a thesis: 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.
