An annotated bibliography is a research tool that forces you to engage with sources. Learning how to write an annotated bibliography in APA format will improve your research papers dramatically.
What is an annotated bibliography?
A list of citations (in APA format) where each citation is followed by a brief paragraph (the annotation) that summarizes, evaluates, and reflects on the source.
Structure of one entry:
- Citation (APA format, hanging indent)
- Annotation (150–250 words)
Step 1: Format the citation correctly (APA 7th edition).
Journal article:
Author, A. A. (Year). Title of article. Journal Title in Italics, volume(issue), page range. https://doi.org/xxxxx
Step 2: Write the annotation with three parts:
Summary (1–2 sentences) – What is this source about?
Evaluation (2–3 sentences) – Is it credible? Strengths and weaknesses?
Reflection (1–2 sentences) – How does this help your research?
Example annotation:
Johnson, L. M. (2021). Social media and adolescent mental health. Journal of Youth Studies, *24*(3), 312–329.
This longitudinal study found that adolescents using social media more than three hours daily had 35% higher depression rates. The study is credible—Johnson is a professor, the journal is peer‑reviewed. However, it relies on self‑reported symptoms. This source will support my argument that time limits on social media could benefit mental health.
Tips:
- Write in your own words
- Be critical, not just descriptive
- Double‑check APA formatting
- Use a citation manager (Zotero, Mendeley)
Learning how to write an annotated bibliography in APA format feels tedious, but it saves time later. You’ll finish research with summaries ready to drop into your paper.
