How you cite a conference paper depends on two things: the citation style you’re using (APA, MLA, Chicago, etc.) and whether the paper was published in a journal, book, or proceedings volume, or simply presented at a conference without formal publication. The format shifts based on those details, but the core elements are the same: author, title of the paper, name of the conference or proceedings, date, and a DOI or URL when available.
Determine How the Paper Was Published
Before you format anything, figure out where the conference paper ended up. This single detail controls which citation template you’ll use. Conference papers generally land in one of four places:
- A journal. Some conferences publish accepted papers as a special issue or supplement of an academic journal. If that’s what you’re citing, treat it as a journal article.
- An edited book or book chapter. Conference proceedings are sometimes collected into a bound volume with an editor. Individual papers within that volume are cited as book chapters; the volume as a whole is cited as an edited book.
- A standalone proceedings volume. Many conferences publish their own proceedings (often as a PDF or on a platform like IEEE Xplore or ACM Digital Library). These follow a format similar to a book chapter, with the proceedings title serving as the container.
- An unpublished presentation. If the paper was only delivered at the conference and never formally published, you cite it as a conference presentation or paper presentation, noting the conference name, location, and date.
Check the source itself. If it has a volume number, issue number, and page range in a journal, it’s a journal article. If it appears inside a larger collection with editors, it’s a book chapter. If it was only delivered orally or posted on a personal website, it’s unpublished.
APA Style (7th Edition)
APA 7th edition covers conference proceedings in Section 10.5 of the Publication Manual. The key rule is that the format mirrors whatever publication type the paper most closely resembles.
Published in a Journal
Use the standard journal article format:
Author, A. A., & Author, B. B. (Year). Title of the paper. Journal Name, Volume(Issue), Page–Page. https://doi.org/xxxxx
Nothing about the conference needs to appear in the reference. If the journal is a special conference issue, the journal title itself usually signals that.
Published as a Book Chapter in Proceedings
This is the most common scenario for fields like computer science, engineering, and linguistics. Use the edited book chapter format:
Author, A. A. (Year). Title of the paper. In E. E. Editor (Ed.), Title of the proceedings (pp. Page–Page). Publisher. https://doi.org/xxxxx
Include the editor’s name if one is listed. If the proceedings don’t name an editor, skip that element and move straight from “In” to the proceedings title.
Unpublished Conference Presentation
For a talk, poster, or paper that was presented but never formally published, include the type of contribution in brackets:
Author, A. A., & Author, B. B. (Year, Month Day–Day). Title of the presentation [Paper presentation]. Name of the Conference, City, State or Country.
Use the specific dates of the conference rather than just the year. The bracketed description (Paper presentation, Poster session, Keynote address) tells the reader what form the contribution took.
MLA Style (9th Edition)
MLA treats conference proceedings using its container model. The individual paper is the work; the proceedings volume is the container. According to the MLA Style Center, you cite a section of proceedings the same way you would an essay in a collection.
The basic format looks like this:
Author Last Name, First Name. “Title of the Paper.” Title of the Proceedings, Conference Dates, edited by Editor Name, Publisher, Year, pp. Page–Page.
Here’s a real example from MLA’s own guidance:
Hualde, José Ignacio. “Patterns of Correspondence in the Adaptation of Spanish Borrowings in Basque.” Proceedings of the Twenty-Fifth Annual Meeting of the Berkeley Linguistics Society, February 12–15, 1999: General Session and Parasession on Loan Word Phenomena, edited by Steven S. Chang et al., Berkeley Linguistics Society, 2000, pp. 348–58.
Notice how the conference dates are part of the proceedings title rather than a separate element. If you accessed the paper online, add the URL or DOI at the end of the entry.
For an unpublished conference presentation in MLA, list the presenter as the author, the title of the talk in quotation marks, the conference name as the container, and the date and location. Describe it as a lecture, keynote address, or conference presentation at the end.
Chicago Style
Chicago offers two systems: notes-bibliography (common in the humanities) and author-date (common in the sciences). For a published conference paper in notes-bibliography style, the footnote and bibliography entry look like a chapter in an edited book:
Footnote: Author First Last, “Title of Paper,” in Title of Proceedings, ed. Editor Name (Place: Publisher, Year), Page.
Bibliography: Author Last, First. “Title of Paper.” In Title of Proceedings, edited by Editor Name, Page–Page. Place: Publisher, Year.
For the author-date system, the format shifts to parenthetical in-text references (Author Year, Page) with a corresponding reference list entry that closely resembles APA’s structure.
Unpublished presentations in Chicago are typically cited in a footnote or endnote only, not in the bibliography, unless the paper is critical to your argument. Include the author, title of the presentation, the phrase “paper presented at,” the conference name, location, and date.
Handling DOIs and URLs
Digital identifiers matter regardless of which style you use. APA’s guidelines are the most detailed and serve as a good baseline for all styles:
- Always include a DOI if one exists, whether you read the paper online or in print. Format it as a full hyperlink: https://doi.org/xxxxx
- If a work has both a DOI and a URL, include only the DOI.
- If there’s no DOI and you found the paper in a standard academic database (like JSTOR or ProQuest), don’t include the URL or database name. The reference should look just like a print citation.
- If there’s no DOI and the paper comes from a website (not a database), include the URL.
- Skip “Retrieved from” or “Accessed from.” The hyperlink alone is sufficient in APA 7th edition.
Standardize all DOIs to the current format recommended by the International DOI Foundation, even if the paper itself shows an older format like “doi:” or “http://dx.doi.org/”. Convert them all to https://doi.org/ followed by the DOI number.
In MLA, add the DOI or URL as the final element of the entry. In Chicago, place it at the end of the note or bibliography entry. Both styles now prefer live hyperlinks over prefatory phrases.
What to Do When Information Is Missing
Conference papers are notorious for incomplete metadata. You might not find an editor, a publisher, page numbers, or even a formal proceedings title. Here’s how to handle each gap:
- No editor listed. Simply omit the editor element. In APA, go from “In” directly to the proceedings title. In MLA, drop the “edited by” clause.
- No page numbers. If the paper was published only online without fixed pagination, leave out page numbers entirely. Some styles allow you to substitute an article number if one is assigned.
- No formal proceedings title. Use the conference name as the title of the container. For example, if a paper was part of the 2024 International Conference on Machine Learning but no separate proceedings title exists, the conference name fills that role.
- No publisher. For proceedings posted on a conference website rather than issued by a press, the sponsoring organization can serve as the publisher. If even that is unclear, omit it and include the URL.
The goal is to give your reader enough information to locate the source. When a standard element is genuinely unavailable, skip it cleanly rather than inventing a placeholder.
In-Text Citations
Once your reference list or bibliography entry is correct, in-text citations follow the normal rules for your style. In APA, use the author’s last name and year in parentheses: (Smith, 2023). In MLA, use the author’s last name and page number: (Smith 348). In Chicago author-date, it mirrors APA. In Chicago notes-bibliography, use a footnote or endnote with the full reference on first mention and a shortened version after that.
For papers with multiple authors, follow each style’s rules for how many names to list before switching to “et al.” In APA, use “et al.” for works with three or more authors starting from the first citation. In MLA, use “et al.” for works with three or more authors. Chicago allows you to list up to three before abbreviating.
