What is a Literature Review?
An overview of the significant literature published on a topic. Rather than evaluating each source separately, a lit review is written in essay form, and explains how each work is similar to and how it varies from the others.

What is an Annotated Bibliography?
An Annotated Bibliography is a list of all the sources you are going to use to write your paper. "Annotations" are short paragraphs that describe and evaluate each one of those sources separately.
Writing an Annotated Bibliography is an excellent resource to understand exactly what an annotated bibliography is, select appropriate resources and suggest useful language for the annotations.
