Citing Sources with No Author or Date
How to cite a source with no listed author, no publication date, or neither, across APA, MLA, Chicago, Harvard, IEEE, and Vancouver.
You find the exact statistic your paper needs on a government fact sheet, but there’s no byline anywhere on the page and no date you can point to. It’s tempting to assume the source is unusable, or worse, to skip the citation entirely because there’s nothing obvious to put in the author slot. Every major style has a documented fallback for exactly this situation – you need to know which substitution goes where.
No Author: Move the Title Into the Author Position
The universal fix across every style is the same: when there’s no identifiable author, the title takes over the author’s position at the start of the citation.
| Style | No-Author Format |
|---|---|
| APA | Title of page. (Year). Site Name. URL |
| MLA | “Title of Page.” Site Name, Day Month Year, URL. |
| Chicago (NB) | “Title of Page.” Site Name. Month Day, Year. URL. |
| Chicago (AD) | “Title of Page.” Year. Site Name. Month Day. URL. |
| Harvard | Title of page (Year) Site Name. Available at: URL (Accessed: date). |
| IEEE / Vancouver | “Title of page,” Site Name, Year. [Online]. Available: URL |
The one detail that changes across styles is capitalization and punctuation of the title itself – sentence case without quotation marks in APA, title case in quotation marks for MLA and Chicago – but the underlying move is identical everywhere: no author means the title leads.
No Date: Use Your Style’s Placeholder
When a page genuinely has no visible publication date, most styles substitute a standard placeholder rather than guessing:
- APA and Chicago (author-date): Use “n.d.” in place of the year, both in the reference entry and the in-text citation: (Smith, n.d.)
- MLA: Omit the date element entirely rather than substituting a placeholder – MLA’s in-text citations don’t include a date to begin with, so the reference entry skips that position entirely
- Chicago (notes-bibliography): Use “n.d.” in the footnote and bibliography, the same as APA
- Harvard: Use “(no date)” in place of the year
- IEEE and Vancouver: Use “n.d.” or omit the year field, following whichever convention your specific journal or institution prefers – check your assignment guidelines, since numbered styles vary more on this point than the alphabetical styles do
Neither Author Nor Date
When a source is missing both, fall back to a shortened title alone, formatted the way your style normally treats a standalone title – quotation marks for a webpage or article, italics if the source functions as a larger standalone work:
APA in-text: (“Global Health Statistics,” n.d.)
MLA in-text: (“Global Health Statistics”)
Chicago footnote: “Global Health Statistics,” n.d.
Before You Give Up: Look Harder First
Most “no author, no date” sources actually have both somewhere on the page – they’re not where you expect. Check these spots before defaulting to the fallback formats above:
- The very bottom of the page. Many articles credit an author in small text below the content rather than at the top.
- The “About” or “Staff” page. Organizational sites often list a named author only on a separate contributors page.
- The page’s metadata. Right-click and view page source, or check the browser’s reader mode – publication dates are sometimes embedded in the code even when they don’t display visually.
- The footer copyright line. A copyright year isn’t the same as a publication date, but it’s a reasonable substitute when nothing else is available, and it’s worth noting in your working document even if you ultimately use “n.d.”
- The Wayback Machine. Archive.org’s snapshot history can show you the earliest date a page existed online, which gives you a defensible approximate date even when the live page shows none.
Organizational Authors Aren’t “No Author”
Before defaulting to a title-led citation, make sure you haven’t mistaken an organizational author for a missing one. If a government agency, nonprofit, or company published the page – even without a named individual – the organization itself is the author:
World Health Organization. (2024). Global health statistics 2024. https://www.who.int/statistics
This is a genuinely different case from true no-author sources, and it’s one of the most common mistakes in this category: students see no personal name and assume “no author,” when the organization listed in the site’s branding or footer should fill that role instead. For more on distinguishing genuinely anonymous sources from organizational ones, see our website citation guide.
Sources with Neither Named Creator
Some source types – an anonymous, uncredited short film, an unsigned wiki edit, a public-domain document with no attribution trail – never had an individual or organizational author to begin with. Uncredited or anonymously distributed films and shows follow the same title-led rule as an unauthored webpage; see our guide on citing a film or TV show if you’re working with a production that doesn’t credit a director by name.
Sorting a No-Author Entry Into Your Reference List
Once you’ve formatted the entry, alphabetize it by the first significant word of the title, skipping “A,” “An,” and “The.” Our guide on alphabetizing a reference list covers exactly where a title-led entry lands relative to author-led ones.
Common Mistakes
- Using “Anonymous” as a stand-in author. Only use the word “Anonymous” if the source is explicitly credited that way – otherwise, lead with the title instead.
- Guessing at a date rather than using “n.d.” An invented date is worse than an honest placeholder; your reader can be misled by a guess but not by an acknowledged gap.
- Missing an organizational author hiding in the footer. Check the “About” page before assuming a source has no author at all.
- Applying MLA’s “omit the date” rule to APA. APA and Chicago author-date both want an explicit “n.d.” placeholder; MLA leaves the date position empty instead.
- Forgetting to check archived versions for a date estimate. The Wayback Machine often resolves a “no date” problem in under a minute.
For a broader list of citation errors beyond missing authors and dates, see our common citation mistakes guide. And if you’re unsure whether a fact even needs a citation in the first place, our guide on when common knowledge doesn’t require one covers that earlier decision.
APA Style documents the “n.d.” convention directly if you want the source guidance for APA specifically.
Try It with CiteTools
Missing metadata is one of the most common reasons students give up on formatting a citation by hand. Paste the URL into CiteTools.io and it fills in whatever it can find automatically – and for the fields that are genuinely missing, it applies the correct placeholder for your style instead of leaving you to guess.
