How do you cite a source with no author?

Move the title into the author position. In APA the reference starts with the title, followed by the date, and the in-text citation uses the title and year: ("Climate Change Impacts," 2024). In MLA the Works Cited entry starts with the title and the in-text citation uses a shortened title. In Chicago the note and bibliography entry start with the title.

How do you cite a website with no author in APA?

First check whether the organization that runs the site is the author; if so, use it: American Red Cross. (2024, March 15). Blood donation FAQ. URL. If there is truly no author, start with the page title: Title of page. (2024, March 15). Site Name. URL. A web page title is italic in an APA reference, so it is italic in the text citation too, followed by the year.

How do you do an in-text citation with no author?

Use the title, or the first few words of it, in place of the author. APA: ("Climate Change Impacts," 2024) for an article, chapter or encyclopedia entry, or an italic title for a book, report or web page. MLA: ("Climate Change" 12). Chicago author-date: ("Climate Change Impacts" 2024).

Do I write Anonymous if there is no author?

No. APA, MLA and Chicago all say to use "Anonymous" only when the work itself is signed "Anonymous." If no author is given, use the title instead.

Can I just put “n.a.” or “no author” in the author field?

No—don't insert placeholder text like “n.a.” into your citation. Instead, restructure the citation to start with the title, as shown above. This is the standard approach across all major styles.

Should I contact the publisher to ask who the author is?

For important sources, yes—this is reasonable, especially for organizational reports or institutional documents. For minor citations, it's probably not worth the effort.

What if I know who wrote it but it's not credited?

If you have strong evidence of authorship (reliable attribution from other sources), some disciplines allow you to add the author in brackets: [Smith, J.]. But be cautious—only do this with solid evidence, and note how you determined authorship.

What if there's no author AND no date?

For APA, you'd have: Title of work. (n.d.). For MLA, just start with the title and omit date information. The source is still citable, but consider whether the missing information affects its credibility.

Is it okay to cite authorless sources?

Yes, many legitimate sources lack individual authors—government reports, organizational statements, reference works. Authorless doesn't mean unreliable. But consider whether the source's authority is clear enough for your purposes.

How to Cite an Anonymous Author or a Source With No Author

The short answer

If a source has no author, the title takes the author's place, both in the reference and in the in-text citation.

Style	Reference list entry	In-text citation
APA 7	Title of article. (2024). Periodical or Site. URL	("Title of Article," 2024); italic instead of quotation marks if the title is italic in the reference
MLA 9	"Title of Article." Website or Publication, 15 Jan. 2024, URL.	("Title of Article")
Chicago notes-bibliography	"Title of Article." Publication, January 15, 2024. URL.	Note: 1. "Title of Article," Publication, January 15, 2024, URL.
Chicago author-date	Title of Work. 2024. Publisher.	(Title of Work 2024)
Harvard (Cite Them Right)	Title of work (2024) Place: Publisher.	(Title of Work, 2024)

Three checks before you use the table:

Look for an organization. A government agency, NGO, company or university that published the page is the author.
Look for a hidden byline at the end of the article, on the About page, or in the PDF properties.
Use "Anonymous" only if the work is signed "Anonymous."

First: Make Sure There Really Isn't an Author

Before treating a source as authorless, dig deeper. Authors are often hidden in unexpected places.

Check these locations: The end of the article (some publications put bylines at the bottom), the "About" page or masthead, PDF metadata (right-click, check properties), the page footer or header, linked author profiles, and press releases or "Contact" sections.

Consider who published it. For organizational publications, the organization itself is often the author. The World Health Organization, the American Psychological Association, or your university's registrar—these count as authors, not authorless sources.

Many sources that seem authorless actually have a corporate or organizational author. Use the organization name as the author when that's the case.

When a Source Is Truly Authorless

If you've checked everywhere and there's genuinely no individual or organizational author, different styles handle this differently:

APA (7th Edition): Move the title to the author position. Use the first few words of the title for in-text citations.

Reference list:

Title of Work. (Year). Publisher. URL

In-text:

("Title of Work," Year)

The in-text form follows the reference: if the title is italic in the reference list (books, reports, web pages), italicize it in the text; if it is not (articles, chapters, encyclopedia entries), put it in double quotation marks.

MLA (9th Edition): Start with the title. Use a shortened version in-text.

Works Cited:

"Title of Article." Publication, Day Month Year, URL.

In-text:

("Title")

Chicago (Notes-Bibliography): Start with the title in notes and bibliography.

Note:

"Title of Article," Publication (Month Day, Year), URL.

Chicago (Author-Date): Similar to APA—title moves to author position.

The "Anonymous" Option

What if the work actually lists "Anonymous" as the author? This is different from no author being listed.

If a source explicitly credits "Anonymous" (rare in modern publishing, more common historically), cite Anonymous as the author:

Anonymous. (Year). Title. Publisher.

In-text: (Anonymous, Year)

Don't use "Anonymous" when an author simply isn't listed. That's misleading—it implies intentional anonymity rather than missing information.

Government and Organizational Documents

These are usually not authorless—they have corporate authors.

Government agencies: Use the agency as author.

U.S. Census Bureau. (2024). Report title. https://census.gov/...

NGOs and nonprofits: Use the organization.

World Health Organization. (2024). Report title. https://who.int/...

Universities and institutions: Use the specific office or department if relevant, or the institution itself.

Office of the Registrar, University of Michigan. (2024). Enrollment report.

When the publisher and author are the same organization, some styles let you avoid repetition. APA, for example, omits the publisher when it's identical to the author. Two source types where this comes up constantly have guides of their own: government documents and reports.

Websites and Web Pages

Corporate websites are a common source of "no author" frustration. Usually, the organization running the website is the author.

American Red Cross. (2024, March 15). Blood donation FAQ. https://redcross.org/...

If you're citing a user-generated wiki (like Wikipedia), the entry has no single author. APA starts with the entry title and asks for the archived version's URL (from "View history"), so readers see the version you used:

List of oldest companies. (2019, January 13). In Wikipedia. https://en.wikipedia.org/w/index.php?title=List_of_oldest_companies&oldid=878158136

For genuinely authorless web pages with no organizational attribution, use the page title. Citing a website works through the whole pattern, and citing Wikipedia explains how to find the permanent link to the version you read.

News Articles Without Bylines

Some news articles, especially brief items and editorials, lack bylines. If the article is credited to a wire service or news agency (for example "By The Associated Press"), that agency is the author. Otherwise start with the headline. Citing a newspaper article covers the print and online forms, and the small differences in how each style writes the page numbers.

APA:

Headline of article. (2024, January 15). The New York Times, A12.

MLA:

"Headline of Article." The New York Times, 15 Jan. 2024, p. A12.

Dictionary and Encyclopedia Entries

Reference works often have authorless entries—that's normal. The citation style reflects this:

APA:

Entry title. (Year). In Dictionary name (edition). Publisher.

MLA:

"Entry Title." Encyclopedia Name, Publisher, Year, pp. xx–xx.

For online versions, include URLs or DOIs. Signed entries do have an author, and telling the two apart is the whole difficulty: see citing a dictionary or encyclopedia entry.

Historical and Archival Documents

Older documents frequently lack clear authorship. For historical sources:

Include as much identifying information as possible. Note the archive or collection where it's held. Describe the document type if relevant. Use approximate dates when exact dates are unknown.

[Unsigned report on trade conditions]. (ca. 1820). Box 3, Folder 7, Smith Family Papers, Historical Society Archive.

Your discipline may have specific conventions for archival citation. Check with your advisor or a disciplinary style guide.

What If Part of Your Citation Is Missing?

Different elements might be missing beyond just the author:

No date: Use "n.d." (no date) in APA; in MLA, simply omit the date.
No page numbers: For online sources, this is normal. For PDFs, use PDF page numbers or section titles.
No title: Describe the content in brackets: [Untitled photograph of market scene].
Multiple missing elements: At some point, consider whether this source is sufficiently identifiable and credible to cite. If you can't tell what it is, when it was created, or who made it, think carefully about whether it belongs in your references.

In-Text Citation for Authorless Sources

The mechanics differ slightly by style but follow the same principle: use the title (or a shortened version) where you'd normally use the author's name.

APA: First few words of title + year: ("Climate Change Impacts," 2024)
MLA: Shortened title: ("Climate Change")
Chicago (Author-Date): Same as APA: ("Climate Change Impacts" 2024)

Keep shortened titles recognizable. Use the first noun phrase or key words—readers should be able to find it in your bibliography.
