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 for further use. Annotations help to to clarify each source, and they will often provide evaluative information as well. Annotations can be any length, but are usually about 50 to 150 words in length.
