Step 3: Write an annotated bibliography. Each of the 10 in your reference list should be followed by a brief (usually about 150 word) descriptive and evaluative paragraph explaining how this source will help to develop your paper. For more information on creating an annotated bibliography, visit: http://www.library.cornell.edu/olinuris/ref/research/skill28.htm .
