Common questions
FAQ
Can I use "bibliography" and "reference list" interchangeably?+
Not in formal academic writing. A reference list contains only cited sources; a bibliography may include uncited background reading. Using the wrong term signals unfamiliarity with your citation style. Check your required style guide: APA calls for "References", Chicago for a "Bibliography".
What is an annotated bibliography?+
An annotated bibliography is a reference list or bibliography in which each entry is followed by a brief descriptive or evaluative note — typically one to three sentences — explaining the source's content, relevance, and quality. It is often assigned as a standalone exercise to help students evaluate sources critically before writing a longer paper.
Does Harvard style use a bibliography or a reference list?+
Harvard (author-date) style typically uses a reference list under the heading "References", containing only sources cited in the text. Some institutions or departments use "Bibliography" as the heading even for author-date styles, so check your specific institutional guide if in doubt.
