How to Write an Annotated Bibliography
Before you can write a literature review, you need a way to track what each source actually says and how it fits into your argument. An annotated bibliography is that tool — and for most University of Fairfax students, it’s one of the first concrete steps toward a dissertation proposal, not just a one-off assignment.
What Is an Annotated Bibliography?
An annotated bibliography is a reference list where each entry is followed by a short paragraph — the annotation — that summarizes the source, evaluates it, and explains how you intend to use it in your own research. It’s different from a standard References page in one key way: a reference list just tells a reader where a source came from; an annotated bibliography tells your committee (or yourself, months later) what that source argues and why it matters to your project.

Is a “Working Bibliography” the Same Thing?
You may hear instructors or committee members use “working bibliography” instead of “annotated bibliography” — they’re closely related, but not always identical. A working bibliography typically refers to the running, evolving list of sources you’re gathering while you research: it may start as just citations with a sentence or two of notes, revised and added to as your project develops. An annotated bibliography usually implies the more complete, polished version — full APA-formatted entries, each with a developed annotation covering summary, evaluation, and application.
In practice, many instructors use the two terms interchangeably for this same assignment, so if yours asks for a “working bibliography,” the guidance on this page still applies — just confirm with them whether they expect the lighter, in-progress version or the fully developed one described below.
Why It Matters More at the Graduate Level
At the dissertation stage, you’ll likely read and track dozens, sometimes hundreds, of sources before you write a single chapter. An annotated bibliography built as you go does two things a reference list alone can’t: it forces you to articulate each source’s argument in your own words early (which prevents the over-reliance on original phrasing that leads to accidental plagiarism later), and it gives you a working map of the literature you can draw on directly when you write your literature review chapter — rather than re-reading fifty sources from scratch once you sit down to write.
What Goes in an Annotation
A typical annotation runs 100–200 words and covers three things:
- Summary — what is the source’s main argument, methodology, or finding?
- Evaluation — how credible or rigorous is it? Who is the author, and what’s their standing in the field? Are there limitations worth noting?
- Application — how does this source relate to your research question, and where might you use it (background, methodology, a counterargument you need to address)?
Not every annotation needs all three in equal depth — a source that’s central to your argument deserves a fuller evaluation than one you’re citing briefly for background.
A Full Worked Example
Reference entry:
Ramirez, J. (2022). Governance structures and cyber resilience in distributed enterprises. Journal of Information Security Management, 18(2), 101–124. https://doi.org/10.1016/j.jism.2022.03.004
Annotation:
Ramirez surveys 42 mid-sized enterprises to argue that organizational governance structure — not technology investment — is the strongest predictor of resilience against sustained cyber threats. The study’s sample is limited to U.S.-based financial and healthcare organizations, so its findings may not generalize to other sectors or regions, a limitation worth noting given this project’s broader industry scope. Ramirez’s governance framework will serve as the theoretical foundation for Chapter 2, and his survey instrument may be adaptable for this project’s own data collection, pending IRB review.
Notice the annotation doesn’t just restate the abstract — it evaluates the study’s limitations and says specifically how it will be used, which is what separates a useful annotation from a summary.
Formatting Your Annotated Bibliography
- Entries are alphabetized by author last name, same as a standard APA reference list.
- The reference entry itself follows standard APA formatting — a hanging indent, double-spaced.
- The annotation paragraph starts on the line directly below the reference entry, indented an additional 0.5 inches from the hanging indent (so the whole annotation block sits one tab further right than the reference line above it), and is also double-spaced.
- Unlike the reference list, no separate “Annotations” heading is needed — the page is typically titled “Annotated Bibliography” instead of “References.”

Building Yours Alongside Your Literature Review
A few practices that make this genuinely useful rather than a one-time assignment:
- Write the annotation right after you finish reading, while the source is fresh — don’t batch this for later.
- Tag or group sources by theme as you go (even informally), so when you reach the writing stage, you can pull all your sources on a given subtopic at once.
- Revisit and revise annotations as your research question sharpens — a source’s relevance often becomes clearer (or less relevant) once your argument takes shape.

FAQ
How long should each annotation be?
Typically 100–200 words — enough to summarize, evaluate, and explain the source’s application to your project, without becoming a second abstract.
Is an annotated bibliography the same as a literature review?
No. An annotated bibliography treats each source individually; a literature review synthesizes multiple sources together to build an argument about the state of the field. The bibliography is usually a step toward writing the review, not a substitute for it.
Does every source in my dissertation need an annotation?
Not necessarily — your program or committee may ask for annotations only during the proposal stage, as a tool for organizing your reading. Check your specific program requirements, since this varies.
Do I need a separate heading for annotations?
No — list each reference entry followed directly by its annotation paragraph; a separate “Annotations” section isn’t standard APA practice.
