Many students have the impression that bibliographic research starts and ends with collecting and reading as many sources as possible. This basic form of research works just fine for small-scale research, such as an essay for class. But for longer-form research that takes months or years to complete, experienced researchers process their sources using an annotated bibliography. The annotated bibliography gives you a convenient way to organize and retrieve information for when you begin to write, which might be months or even years after you’ve initially read the paper.
The good news is that writing an annotated bibliography is not a very complicated process. For every paper/resource that you retrieve for your research, you should copy the following headings and fill in the information.
Write the citation in the correct style for your paper. (If you don't know how to write a bibliographic citation, please refer to our “How to Write A Bibliography” guide, which gives detailed instructions.)
Each entry should be concise--one sentence or phrase per bullet point, so the whole thing is a paragraph (~150 words) long. Don't include any background notes or cross-references in the annotation, the info here should only be about the source you're citing. When in doubt, ask your mentor how they would like for you to format your annotations so you don’t waste time writing the wrong way!
