Annotated Bibliography

Build an entry from its three parts, with the mechanical checks a marker will notice.

In whatever style your brief asks for. The citation generator will build one if you need it.
Annotation type

Evaluative — plus how good and how useful it is · target 120–200 words.

What the source argues and how it got there — its question, method and main finding.

0 words

How good it is — the authority behind it, the strength of the evidence, any bias or limit.

0 words

What it does for your project — which part of your argument it supports, complicates or replaces.

These are mechanical checks — counts and patterns visible in the text. Whether the evaluation is any good is a judgement no word count can make.

An annotated bibliography entry is a citation followed by a short paragraph doing three jobs: summarising the source, evaluating it, and saying what it does for your project. Most marks are lost by writing only the first.

The three moves, and why the second one is the point

Summarising is the easy part, and it is the part that feels like work — you read the thing, you say what it said. But a summary proves only that you read it. The evaluation is what proves you can judge it: who wrote it and on what authority, how strong the evidence is, what the method cannot see, where the argument is weakest. That is the move a marker is looking for, and it is the one most often missing.

The third move is the one that makes a bibliography annotated rather than merely descriptive. It answers a question only you can answer: what is this source doing in your project? A source that supports your argument, one that complicates it, and one that you intend to argue against all deserve entries, and the reflection is where that difference gets recorded.

How long, and why it varies

A descriptive annotation runs about 75 to 120 words and stops at the summary. An evaluative one runs to roughly 120 to 200 and adds the judgement. An extended critical annotation can reach 300. The brief decides which you are writing, and it is worth checking before you start, because an entry that is the wrong type is not fixed by being well written.

citation + summary + evaluation + reflection = one entry

one paragraph, not three; the citation carries a hanging indent

  1. 1
    Write the citation first, in the required style. APA, MLA, Chicago or Harvard — whatever the brief says. Entries are alphabetised by it.
  2. 2
    Summarise in two or three sentences. The question the source asks, how it went about answering it, and what it found. Paraphrase, do not quote.
  3. 3
    Evaluate it. Author’s standing, quality and quantity of evidence, method, scope, any bias. Be specific: “a sample of 40 undergraduates” beats “a small sample”.
  4. 4
    Say what it does for you. Which part of your argument it supports, undermines or reframes — and if you will argue against it, say so here.
  5. 5
    Join them into one paragraph and check the length. The three parts are a drafting aid, not a structure the reader sees. An evaluative annotation lands around 120 to 200 words.

What each type is for

Check the brief before drafting — writing the wrong type well still loses marks.

What the checks here can and cannot tell you

The tool counts words per section, counts sentences, and looks for patterns that are visible in the text: a missing section, an evaluation dwarfed by the summary, quotation marks where paraphrase belongs, sentences over forty words, first-person pronouns beyond a handful. Each of those is a real and common failure, and each is something a machine can genuinely detect.

What no count can do is judge whether the evaluation is any good. “The evidence is weak” and “the study measures self-reported behaviour rather than observed behaviour, so it cannot support the causal claim it makes” have the same word count and are not the same sentence. The checks are there to catch the structural problems so you can spend your attention on the part that needs judgement.

Two conventions worth knowing. Entries go in alphabetical order by the citation, exactly as in a reference list — not grouped by theme unless the brief asks for it. And the annotation is one paragraph, indented under its citation; the three-part split exists only while you draft. If your brief asks for headed subsections instead, follow the brief, since local requirements vary more here than in most academic formats.

What goes in an annotated bibliography entry?
A full citation, then a paragraph that summarises the source, evaluates its quality and says what it contributes to your project. The evaluation and the reflection are what distinguish it from a reference list.
How long should each annotation be?
It depends on the type. Descriptive annotations run 75 to 120 words, evaluative ones 120 to 200, and extended critical ones up to 300. Check the brief before drafting.
What is the difference from a literature review?
An annotated bibliography treats each source separately, in alphabetical order. A literature review synthesises them into a single argument about the state of the field, organised by theme rather than by author.
Should I write in the first person?
Usually yes in the reflection, where you are saying what the source does for your work, and not elsewhere. Some courses want the whole annotation impersonal, so check.
Can I quote the source?
Better not to. Space is tight and paraphrase demonstrates that you understood the argument, which quotation does not. Save the quotations for the essay itself.
How do I order the entries?
Alphabetically by the first element of the citation, exactly as in a reference list, unless the brief asks for thematic grouping.
What does a good evaluation actually say?
Something specific enough to be wrong. Name the method, the sample, the scope or the funding, and say what those allow the source to show and what they do not. “The evidence is weak” says nothing a marker can credit.
