An annotated bibliography is a list of citations of books, articles and other secondary sources. Each citation should be followed by a descriptive and evaluative paragraph that informs the reader of the accuracy, relevance and quality of the cited source. Annotations are usually about 150 words each. Annotations are more than summaries because they evaluate the worth of sources on the list.
