Works Cited vs. References vs. Bibliography
Works cited vs references comes down to citation style: MLA calls its source list a Works Cited, APA calls it References, and Chicago typically calls it a Bibliography. All three list your sources, but the label, formatting, and what may be included differ.
What is the difference between works cited, references, and a bibliography?
The difference is mostly a matter of citation style and scope: a Works Cited (MLA) and a References list (APA) contain only the sources you actually cited in the text, while a Bibliography (traditional Chicago and general usage) can list every source you consulted, whether or not you cited it. The label you use is dictated by the style guide your instructor or publisher requires, not by personal preference.
All three appear at the end of a paper, sort entries alphabetically by the first author’s last name, and use a hanging indent, where the first line sits flush left and subsequent lines indent. What changes between them is the heading, the order of elements, punctuation, and capitalization.
| Feature | Works Cited | References | Bibliography |
|---|---|---|---|
| Primary style | MLA (9th ed.) | APA (7th ed.) | Chicago (17th/18th) |
| Includes | Only cited sources | Only cited sources | Cited plus consulted sources |
| Date position | Near the end | Right after author | Near the end |
| Title case | Title Case | Sentence case | Title Case |
| Author names | Full first name | Initials only | Full first name |
When do you use a works cited, references, or bibliography page?
Use the list your assigned style requires: MLA papers in the humanities use a Works Cited, APA papers in the social sciences and psychology use References, and Chicago papers in history and the arts use a Bibliography. Choosing the wrong heading is a formatting error even when the entries themselves are correct.
Chicago is the common source of confusion because it has two systems. The notes and bibliography system uses footnotes or endnotes plus a Bibliography, and is favored in history and literature. The author-date system uses parenthetical citations plus a list titled References, mirroring APA. So “Chicago always means bibliography” is a myth; the label depends on which Chicago system you use.
- Works Cited — MLA, and any assignment that specifies MLA formatting.
- References — APA, Chicago author-date, IEEE, AMA, and most science styles.
- Bibliography — Chicago notes and bibliography, Turabian, and any task asking for background reading.
How do in-text citations differ across the three?
Each style pairs its source list with a matching in-text format, and the two must agree. MLA uses author and page number with no comma, APA uses author and year, and Chicago notes and bibliography uses a superscript number tied to a footnote. Every in-text citation must point to an entry in the corresponding end list.
For the same quotation from a book by Barbara Kingsolver, the parenthetical citations look like this:
MLA(Kingsolver 45)
APA(Kingsolver, 2022, p. 45)
Chicago author-date(Kingsolver 2022, 45)
In Chicago’s notes and bibliography system there is no parenthetical citation at all; you place a numbered note instead, such as: 1. Barbara Kingsolver, Demon Copperhead (New York: Harper, 2022), 45. The full entry then reappears, alphabetized, in the Bibliography.
How are the entries formatted in each list?
The end-of-paper entry reorders the same facts, author, title, publisher, and date, according to each style’s rules. MLA and Chicago keep full first names and title-case titles, while APA reduces first names to initials and uses sentence case for book and article titles. Below is one book cited three ways.
The same book, three styles
MLA Works CitedKingsolver, Barbara. Demon Copperhead. Harper, 2022.
APA ReferencesKingsolver, B. (2022). Demon Copperhead. Harper.
Chicago BibliographyKingsolver, Barbara. Demon Copperhead. New York: Harper, 2022.
A journal article, three styles
Journal articles show the differences most clearly, because APA moves the year forward and lowercases the article title, while MLA and Chicago keep title case and place the date later.

Works cited vs. bibliography: is there real overlap?
Yes, the two overlap heavily but are not interchangeable, because a Works Cited is a subset of what a Bibliography can hold. A Works Cited or References list must exclude any source you did not cite, whereas a Bibliography may add works you read for context but never quoted. Padding a Works Cited with uncited sources is an error; padding a Bibliography is acceptable.
Two related headings appear in Chicago and Turabian papers. A Selected Bibliography lists only the most important sources, and an Annotated Bibliography follows each entry with a short paragraph summarizing and evaluating the source. If your assignment asks you to comment on each source, you need an annotated list rather than a plain Works Cited.
How accurate is this guide, and what mistakes should you avoid?
This guide reflects the current editions in wide use in 2026: MLA 9th edition, APA 7th edition, and Chicago 17th and 18th editions. Style manuals do update, and instructors sometimes impose house rules, so treat any generator output as a strong draft that you should proofread against your assignment sheet rather than as the final word.
The most common mistakes are structural, not typographical:
- Mixing the label and the format. An APA paper needs the heading “References,” not “Bibliography,” even if the entries are otherwise correct.
- Listing uncited sources in a Works Cited. Only sources with a matching in-text citation belong there; move background reading to a Bibliography.
- Wrong capitalization. APA uses sentence case for article and book titles; MLA and Chicago use title case.
- Dropping the hanging indent or failing to alphabetize by the first author’s surname.
- Losing DOIs or URLs that APA and current MLA both expect for online sources.
Automated tools catch punctuation and ordering reliably, but they cannot judge whether a source was actually cited in your text. That final check is always yours.
Frequently asked questions
Is a works cited the same as a bibliography?
No. A works cited lists only the sources you cited in your paper, while a bibliography can also include sources you consulted but never cited. A works cited is essentially a narrower, cited-only version of a bibliography.
Does APA use works cited or references?
APA uses “References.” The heading “Works Cited” belongs to MLA. Using “Works Cited” on an APA paper, or “References” on an MLA paper, is a formatting error even when the entries are correct.
What does Chicago style call its source list?
It depends on the system. Chicago’s notes and bibliography system uses a “Bibliography,” while its author-date system uses a list titled “References,” much like APA.
Can a works cited page include sources I did not cite?
No. Every entry in a works cited or references list must correspond to an in-text citation. Sources you read for background but did not cite belong in a bibliography instead.
Which is correct, references or bibliography?
Both are correct in the right context. Use “References” for APA and Chicago author-date, and “Bibliography” for Chicago notes and bibliography or when your assignment asks for all consulted sources.
Do all three lists use a hanging indent and alphabetical order?
Yes. MLA, APA, and Chicago all sort entries alphabetically by the first author’s last name and apply a hanging indent, so the first line is flush left and later lines are indented.
