You can browse Purdue Owl's definition, guidelines, and examples of annotated bibliographies here. Also included on this webpage is an explanation for why you should write an annotated bibliography and how it can help you in the research process.
This example above is meant to show how an annotated bibliography could look. Please check your professor's instructions to see what they specifically are looking for. Some annotated bibliographies only need a couple of sentences for the "annotation" portion. Some require a lengthier "annotation." The example here is on the lengthier side.
