A bibliography is a formatted list of sources (books, articles, videos, news, websites, etc.) on a topic.
Annotations vs. Abstracts
Abstracts are the purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes. Annotations are descriptive and critical; they expose the author's point of view, clarity and appropriateness of expression, and authority.
