The purpose of an annotated bibliography is to describe the cited material, whether a book, article or other type of source. It is a brief, descriptive note that should provide sufficient information so that a determination can be made as to whether the source should be examined further for use. Annotations help to clarify each source, and they will often provide evaluative information as well.
What you should include: most annotations are between 50 and 150 words.
An annotation should:
NOT be a book review or abstract
