Annotated bibliography

An annotated bibliography is a list of citations where each entry is followed by a short paragraph — the annotation — that summarises the source and, usually, evaluates it or explains why it matters to your project.

How to format it

  1. Write the full citation in your required style (APA, MLA or Chicago) with a hanging indent.
  2. Start the annotation on the next line, indented as a block (APA: 0.5 inch; MLA: 1 inch from the left margin, per the MLA Style Center).
  3. Alphabetise entries by author, exactly like a normal reference list, and title the page “Annotated Bibliography”.

Three kinds of annotation

KindWhat it does
SummaryStates the main argument, the evidence or method, and the conclusion. Neutral, third person.
EvaluativeSummarises, then judges: Is the author qualified? Is the evidence strong, recent, large enough? What are the limits?
ReflectiveSummarises, then explains how the source shapes your own research — what it supports, challenges or leaves open.

Example (APA, evaluative)

Annotated BibliographyAPA 7

Kahneman, D. (2011). Thinking, fast and slow. Farrar, Straus and Giroux.

Kahneman, a psychologist and Nobel laureate in economics, synthesises decades of research on judgment into a model of two systems: fast, intuitive System 1 and slow, deliberate System 2. Drawing largely on experiments he conducted with Amos Tversky, he shows how System 1 produces predictable biases such as anchoring and loss aversion. The book is accessible and authoritative, although some of the priming studies it cites have since failed to replicate, so individual findings should be checked against newer work. It gives my paper its core framework for explaining exam-day decision errors.

Annotation helper

Paste the abstract and your own notes on one source. The helper drafts an annotation from what you give it — it doesn’t read the source for you, and you should rewrite the draft in your own voice.

Annotated bibliography questions

How long should an annotation be?

Usually 100–200 words (roughly one paragraph) per source, unless your instructor sets a different length.

Is an annotation the same as an abstract?

No. An abstract only summarises and is written by the author. An annotation is written by you and, for evaluative or reflective annotations, judges the source and explains how it serves your research.

Can I use AI to write my annotations?

Only if your instructor allows it. The CiteFast helper is designed as a starting draft built only from notes you provide; you still need to read the source and rewrite the draft in your own words. Many institutions treat undisclosed AI text as misconduct.

Is an annotated bibliography double-spaced?

In APA and MLA, yes — both the citation and the annotation. Chicago bibliographies are usually single-spaced within entries.
