Here’s a guide from Cornell University on how to create an annotated bibliography.
The guide gives the following example of an entry:
Waite, Linda J., Frances Kobrin Goldscheider, and Christina Witsberger. “Nonfamily Living and the Erosion of Traditional Family Orientations Among Young Adults.” American Sociological Review 51.4 (1986): 541-554. Print.
The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.
The writer of this annotation compares it to another source he or she is using, which is great. Remember, in the annotated bibliography you create for English 102, I want you to be really explicit in stating how each source will be used.
