An annotated bibliography is a list of sources followed by a brief (around 150 words) paragraph explaining the quality, relevance, and accuracy of the source. An annotated bibliography is often the first step in writing a paper.
Your professor may require specific information in your annotations. Check your assignment instructions carefully for details. Below are some items that may be required.
Summarize: Some annotations just summarize the source.
Assess: After you summarize a source, it may be helpful to evaluate it.
Reflect: Next, determine how the source fits into your research.
