Frequently asked questions

What is an annotated bibliography?

An annotated bibliography is a list of citations to sources, where each citation is followed by a short paragraph (the annotation) that summarizes, evaluates, and reflects on the source's relevance to your research.

How long should each annotation be?

Most annotations are 100–200 words. A typical annotation summarizes the source, assesses its credibility or bias, and explains how it fits your project — but always follow your instructor's guidelines.

Which citation styles are supported?
