How to Cite Sources Without Authors in APA, MLA & Chicago

TL;DR — Key Takeaways

  • No personal author? Use the organization name as the author. This includes Wikipedia, government agencies, corporations, and nonprofits.
  • No organization AND no person? Move the title to the author position. Don’t write “no author” anywhere — that’s incorrect in all three styles.
  • No date? Use “n.d.” (no date) for APA and Chicago. MLA omits the date entirely.
  • “n.d.” placement matters: It goes where the year would normally be, not at the end. This is the most common mistake.
  • No author AND no date? Handle both missing elements: title goes in author position, “n.d.” goes in date position.

You’ve been researching for two hours. You’ve got the perfect source — a Wikipedia page, a government report, maybe even a blog comment. But when you go to cite it, you hit a wall. There’s no author name. No publication date. Nothing to put in the Author field of your citation generator.

This is one of the most common citation headaches students face. And the rules for handling missing information are surprisingly specific — and surprisingly easy to get wrong.

If your citation style guide doesn’t cover this, or if your professor’s handout skipped the edge cases, here’s exactly how to handle sources with missing metadata in APA 7, MLA 9, and Chicago 17.

Why You’re Running Into Missing Author Names

Before we dive into the rules, let’s talk about why this happens so often. You’re not doing anything wrong — sources simply don’t always come with clear author attribution. Here’s what you’ll actually encounter:

  • Wikipedia pages: Hundreds of contributors, no single named author
  • Corporate annual reports: Published by the company, not a specific person
  • Government documents: Agency-published without individual attribution
  • Blog comments: Often signed “Anonymous” or just a username
  • Social media posts: Platform handles instead of real names
  • News articles from wire services: Associated press pieces, government releases

These aren’t edge cases — they’re mainstream sources students cite across every discipline. The difference between passing your paper and losing points on citations often comes down to handling these scenarios correctly.

Scenario 1: Organizational Authors (The Most Common Fix)

When an individual person isn’t listed as the author, the organization that published the source becomes the author. This isn’t a workaround — it’s the official rule in all three styles.

APA 7 — Organizational Author

World Health Organization. (2024). Mental health: A priority for global health. https://www.who.int/mental-health

In-text: (World Health Organization, 2024) or (WHO, 2024) if you abbreviate earlier

MLA 9 — Organizational Author

World Health Organization. "Mental Health: A Priority for Global Health." WHO, 2024, https://www.who.int/mental-health.

In-text: (World Health Organization)

Chicago Notes-Bibliography — Organizational Author

World Health Organization. "Mental Health: A Priority for Global Health." WHO, last modified 2024. https://www.who.int/mental-health.

Footnote: World Health Organization, “Mental Health: A Priority for Global Health,” WHO, last modified 2024. https://www.who.int/mental-health.

Real Example: Wikipedia

Wikipedia is one of the most cited sources across all disciplines. Since no individual author is visible, the organization name serves as the author:

APA: Wikipedia. (2025, June 12). Artificial intelligence. https://en.wikipedia.org/wiki/Artificial_intelligence

MLA: Wikipedia. “Artificial Intelligence.” Wikipedia, 12 June 2025, https://en.wikipedia.org/wiki/Artificial_intelligence.

Chicago NB: Wikipedia. “Artificial Intelligence.” Wikipedia, last modified June 12, 2025. https://en.wikipedia.org/wiki/Artificial_intelligence.

Real Example: Corporate Annual Report

APA: Tesla Inc. (2024). Annual report 2024. https://www.tesla.com/annual-report

MLA: Tesla Inc. “Annual Report 2024.” Tesla, 2024, https://www.tesla.com/annual-report.

Chicago NB: Tesla Inc. “Annual Report 2024.” Tesla, 2024. https://www.tesla.com/annual-report.

Scenario 2: No Author — Title in the Author Position

When neither a person nor an organization is identifiable, you move the title to the author position. This is where most citation mistakes happen — students literally write “no author” instead of following the style’s rules.

The Golden Rule: Never Write “No Author”

Putting “no author” in a citation is incorrect in APA 7, MLA 9, and Chicago 17. All three styles tell you to use the title instead.

APA 7 — No Author

"Mental Health Statistics." Centers for Disease Control and Prevention, 2025. https://www.cdc.gov/mentalhealth/stats
  • The title goes into the author slot
  • In-text: (“Mental Health Statistics,” 2025) — note the quotation marks
  • If the title is longer than one line, use a hanging indent and fold it to the right

MLA 9 — No Author

"Mental Health Statistics." Centers for Disease Control and Prevention, 2025, https://www.cdc.gov/mentalhealth/stats.
  • Same approach: title moves to author position
  • In-text: (“Mental Health Statistics”)

Chicago NB — No Author

"Mental Health Statistics." Centers for Disease Control and Prevention, last modified January 10, 2025. https://www.cdc.gov/mentalhealth/stats.
  • Title moves to the note position
  • For the footnote: “Mental Health Statistics,” Centers for Disease Control and Prevention, last modified January 10, 2025. https://www.cdc.gov/mentalhealth/stats.

Example: Undated Government Page

Let’s say you’re citing a government resource with no author and no date:

APA: “Student Loan Forgiveness Program.” U.S. Department of Education, n.d. https://www.ed.gov/loan-forgiveness

MLA: “Student Loan Forgiveness Program.” U.S. Department of Education, n.d., https://www.ed.gov/loan-forgiveness.

Chicago NB: “Student Loan Forgiveness Program.” U.S. Department of Education, accessed July 10, 2025. https://www.ed.gov/loan-forgiveness.

Scenario 3: Missing Date — The “n.d.” Rule

When you have a clear author but no date, APA and Chicago use n.d. (stands for “no date”). MLA doesn’t use “n.d.” — it simply omits the date.

APA 7 — No Date

Smith, J. A. (n.d.). Understanding anxiety disorders. MindHealth. https://www.mindhealth.org/anxiety

In-text: (Smith, n.d.)

Important: “n.d.” goes where the year normally goes — in the parentheses immediately after the author.

MLA 9 — No Date

Smith, Jane A. "Understanding Anxiety Disorders." MindHealth, n.d., https://www.mindhealth.org/anxiety.

MLA places “n.d.” where the date would normally appear. However, MLA is flexible — if you accessed the page recently and the content hasn’t changed, you can simply omit the date and add your access date at the end instead:

Smith, Jane A. "Understanding Anxiety Disorders." MindHealth, accessed July 10, 2025, https://www.mindhealth.org/anxiety.

Chicago 17 — No Date

Notes-Bibliography: Use the access date instead of a publication date:

Smith, Jane A. "Understanding Anxiety Disorders." MindHealth, accessed July 10, 2025. https://www.mindhealth.org/anxiety.

Author-Date: Use “n.d.”:

Smith, Jane A. n.d. "Understanding Anxiety Disorders." MindHealth. https://www.mindhealth.org/anxiety.

In-text (Author-Date): (Smith n.d.)

The “n.d.” Placement Mistake

The single most common error with “n.d.” is putting it in the wrong place. Here’s what NOT to do:

  • ❌ Smith, J. A. Understanding anxiety disorders. (n.d.). — wrong position
  • ✅ Smith, J. A. (n.d.). Understanding anxiety disorders. — correct

“n.d.” goes in the parentheses where the year belongs, not at the end of the entry.

Scenario 4: No Author AND No Date (The Edge Case)

This is the scenario that most guides skip — but it happens more often than you’d think. A government page, a Wikipedia article, or a blog post with no named author and no date.

APA 7 — No Author and No Date

"Mental Health Awareness Week." World Health Organization, n.d. https://www.who.int/awareness-week
  • Title goes in author position
  • “n.d.” goes in date position
  • In-text: (“Mental Health Awareness Week,” n.d.)

MLA 9 — No Author and No Date

"Mental Health Awareness Week." World Health Organization, n.d., https://www.who.int/awareness-week.

Chicago NB — No Author and No Date

"Mental Health Awareness Week." World Health Organization, accessed July 10, 2025. https://www.who.int/awareness-week.
  • Since there’s no date, use the access date
  • Title goes in author position

Chicago Author-Date — No Author and No Date

"Mental Health Awareness Week." World Health Organization, n.d. https://www.who.int/awareness-week.

In-text: (“Mental Health Awareness Week,” n.d.)

Special Cases Students Actually Cite

Blog Comments Signed “Anonymous”

If a blog comment is signed “Anonymous,” treat it as no author:

APA: “Anonymous.” (2024, August 5). Comment on post title. The Tech Blog. https://www.thetechblog.com/post

MLA: “Anonymous.” “Comment on Post Title.” The Tech Blog, 5 Aug. 2024, https://www.thetechblog.com/post.

Social Media Posts by Handle

When someone posts on social media with a username (not a real name):

APA: @username. (2025, March 15). Tweet title [Description of the form]. Twitter. https://twitter.com/username/post

MLA: @username. “Post text.” Twitter, 15 Mar. 2025, https://twitter.com/username/post.

Side-by-Side Comparison

Here’s how the same source — a Wikipedia page about climate change with no individual author — looks in all three styles:

Element APA 7 MLA 9 Chicago NB
Author position Wikipedia Wikipedia Wikipedia
Date (n.d.) after author n.d. after website accessed July 10, 2025
Title “Climate change.” “Climate Change.” “Climate Change.”
Website Not in entry (part of title) Wikipedia after title Wikipedia after title
URL Included Included Included
In-text (“Climate change,” n.d.) (“Climate Change”) Footnote on first mention

Example Entry

APA: Wikipedia. “Climate Change.” https://en.wikipedia.org/wiki/Climate_Change

MLA: Wikipedia. “Climate Change.” Wikipedia, n.d., https://en.wikipedia.org/wiki/Climate_Change.

Chicago NB: Wikipedia. “Climate Change.” Wikipedia, accessed July 10, 2025. https://en.wikipedia.org/wiki/Climate_Change.

What Goes Wrong Most Often

Putting “n.d.” at the End of the Citation

Incorrect: Smith, J. A. Understanding anxiety disorders. n.d.

Correct: Smith, J. A. (n.d.). Understanding anxiety disorders.

“n.d.” belongs where the year goes — right after the author’s name in parentheses.

Writing “No Author” Literally

This is the most common mistake across all three styles. Never write “no author” in a citation. Use the title instead.

Mixing Up MLA and APA for Missing Dates

APA uses “n.d.” MLA doesn’t require “n.d.” but accepts it. Chicago uses access dates instead. Don’t apply “n.d.” across all three styles.

Using the Access Date When You Should Use a Publication Date

Even if you didn’t see a date on the page, check the Wayback Machine or view page source — many sites hide dates in meta tags. Don’t default to “accessed” just because you’re lazy.

Decision Tree: Missing Metadata Quick Reference

When your source is missing data, follow this flow:

  1. Is there a personal author? (named individual)
    • Yes → Use their name normally
    • No → go to step 2
  2. Is there an organization that published the source? (Wikipedia, CDC, Tesla, etc.)
    • Yes → Use the organization name as the author
    • No → go to step 3
  3. Is there a title?
    • Yes → Move the title to the author position
    • No → This is extremely rare; contact your professor
  4. Is there a date?
    • Yes → Include it normally
    • No → Use “n.d.” (APA/Chicago) or omit (MLA)
  5. Is the content unstable? (feeds, wikis with active edits)
    • Yes → Add “Retrieved from” (APA only)
    • No → Skip “Retrieved from”

Citation Tool Warnings

Citation generators (Zotero, Citation Machine, MyBib) are convenient, but they struggle with missing metadata:

  • They can’t find dates hidden in meta tags
  • They may place “n.d.” incorrectly
  • They often format organizational authors wrong
  • They don’t handle “no author AND no date” correctly

Always verify generator output against the APA Style Guide or Scribbr’s missing-author examples. The official sources have accurate examples that generators consistently miss.

Quick Reference Checklist

Save this before your next paper.

  • [ ] Check for personal author → if none, use org name
  • [ ] Check for organization → if none, move title to author position
  • [ ] Check for date → if none, use “n.d.” (APA/Chicago) or omit (MLA)
  • [ ] Check “n.d.” placement → must be in parentheses after author, not at end
  • [ ] Check in-text citation format → matches bibliography style
  • [ ] Verify citation generator output against official examples

Missing author names and dates won’t ruin your paper — but treating them as excuses rather than problems will. The rules for handling missing metadata are straightforward once you know them, and they’re easy to double-check.

When you’re researching and a source looks perfect but has no author or date, don’t panic. Follow the decision tree above, and your citation will be accurate regardless of what’s missing.
