Annotated Bibliography
What an annotated bibliography is and how per-source annotations differ from the synthesized argument of a literature review.
Definition
An annotated bibliography is a citation list in which each source carries a short annotation summarizing, evaluating, and situating that source for the writer's project.
Why it matters
Annotations document the reading stage of a project, so instructors use them to verify engagement with sources before the synthesis work of a literature review begins.
Related terms
See literature review, synthesis matrix, and citation integrity: the bibliography documents sources individually, the matrix reorganizes them by theme, and citation integrity keeps every entry verifiable against the real source.

What is an annotated bibliography?
An annotated bibliography is a list of full citations in which each entry is followed by a short annotation, usually 100 to 200 words. A good annotation summarizes the source's question, method, and findings, evaluates its credibility and limitations, and states its relevance to the writer's own project rather than only restating the abstract.
How does an annotated bibliography differ from a literature review?
An annotated bibliography treats sources one at a time, each in its own entry, while a literature review synthesizes across sources by theme and argument. Many writing programs assign the bibliography first as a documented reading stage, then expect the writer to reorganize that material thematically, often through a synthesis matrix, before drafting the review.
What makes an annotation strong rather than superficial?
A strong annotation shows the writer actually read the source: it names the study design or argument type, reports specific findings rather than vague praise, notes limitations or scope conditions, and connects the source to the writer's question. Copying the abstract, or generating annotations for unread sources, defeats the assignment's purpose of documented reading.
Preguntas frecuentes
Should annotations quote the source?
Sparingly. Short verbatim quotations with page references can anchor an evaluation, but the annotation should mostly be the writer's own assessment.
Is an AI-generated annotation acceptable?
Policies vary, but the assignment's purpose is documented reading. Generated annotations for unread sources typically violate that purpose and most disclosure policies.
