Generally, an annotation is approximately 100-300 words in length (one paragraph). However, your professor may have different expectations so it is recommended that you clarify the assignment guidelines.
An annotation may include the following information:
- A brief summary of the source
- The source’s strengths and weaknesses
- Its conclusions
- Why the source is relevant in your field of study
- Its relationships to other studies in the field
- An evaluation of the research methodology (if applicable)
- Information about the author’s background
- Your personal conclusions about the source
