This document provides instructions for writing an annotated bibliography. It defines an annotated bibliography as a list of sources with brief notes, or annotations, for each that summarize, evaluate, and explain how the source will be used. The document outlines the four parts of each annotation: the MLA citation, a 2-3 sentence summary, a 5 sentence evaluation of the source's credibility, and a 1-2 sentence explanation of how the source will be used. It also provides an example of an annotation for an article on deer-vehicle collisions and daylight saving time. Resources for writing annotated bibliographies are listed at the end.
