Chicago Author-Date Website Citation with No Author
In Chicago Author-Date, when a webpage names no individual author, you can usually begin the reference with the page title, then add the year, website title, any month-day update detail, and the URL. If the site owner clearly takes responsibility for the page, Chicago also allows using that organization as the author.
Use this guide when a webpage has no named person author. If you also need the matching in-text citation, see Chicago Author-Date In-Text Citations for Websites with No Author.
When a Chicago Author-Date webpage has no named author
Start with the webpage title in quotation marks if no person or clearly credited group author is available.
Put the year immediately after the first element. If no date is available, use n.d..
Put the website title in italics when you include it, then add any month-day update detail the page gives.
If the site owner clearly acts as the author, Chicago allows using that organization as the author instead of forcing a title-first entry.

Chicago Author-Date Rules for Website References with No Author
First decide whether the site owner should count as the author
Chicago does not force every no-byline webpage into the same pattern. If the site owner or responsible organization clearly stands behind the page, Chicago Author-Date can use that owner as the author.
If the page is simply published on a site but no person or organization is clearly credited for the content itself, a title-first reference is usually the cleaner choice.
Pick one pattern and keep the matching in-text citation aligned with the way the reference entry begins.
If no author is being used, begin with the full webpage title
In a title-first Chicago Author-Date reference, place the full webpage title in quotation marks and keep headline-style capitalization.
Do not shorten the title in the reference list entry. Shortened titles belong to the matching in-text citation, not to the full reference.
This is one of the clearest style differences on this topic. Chicago keeps the webpage title in quotation marks and does not switch it to the italic title-first pattern that APA uses.
Put the year immediately after the first element
Chicago Author-Date anchors the reference entry around the year. If the entry starts with a title, the year follows that title. If the entry starts with an organization name, the year follows the organization.
Use the year from the page's publication or update information. If the page provides no usable date, Chicago allows n.d. in the year position.
Do not leave the year position blank in an undated Chicago Author-Date entry. The style keeps that slot visible even when the answer is n.d..
Add the website title and any month-day update detail
After the year and the page title, give the website title. When you include it as a separate element, Chicago treats that website title as italic type.
If the page shows a fuller date such as June 18, 2025, the year is already handled at the front of the entry, so the later date detail can usually be reduced to the remaining month and day.
If the website title and the organization author are the same, Chicago often omits the repeated website title instead of listing the same wording twice.
Finish with the URL and consider an access date for undated or changing pages
End the reference with the direct URL of the specific webpage and a final period.
Access dates are optional in Chicago Author-Date, but they are often useful when the page is undated or designed to change over time.
A Chicago access date is not a replacement for the year slot. If the page is undated, keep n.d. and add the access date only as extra context when it helps readers recover the source.
How Chicago Author-Date Differs on This Issue
Chicago handles no-author webpages differently from both APA and MLA. APA moves the title into an italicized title-first reference and uses (n.d.) in parentheses when no date is available.
MLA also allows title-first entries and also italicizes the website title, but it usually omits the date rather than writing n.d.. Chicago keeps the webpage title in quotation marks, places the year right after the first element, and preserves a visible year slot even for undated sources.
How to Format a Chicago Author-Date Website Citation with No Author
Use this sequence when a webpage has no named person author.
- Check whether a responsible organization or site owner is clearly acting as the author.
- If not, move the full webpage title to the first position and keep it in quotation marks.
- Add the publication or update year immediately after the first element.
- If the page has no usable date, write n.d. in the year position.
- Add the website title in italics if you include it.
- If the page shows a fuller update date, add the remaining month-day detail after the website title.
- If the organization author and website title are identical, omit the duplicate website title.
- Finish with the direct URL and a final period.
- If the page is undated or likely to change, add an access date after the title block and before the URL.
- For the matching in-text citation, shorten the title only if the reference entry begins with the title.

Common Mistakes in Chicago Author-Date Website Citations with No Author
Moving the year after the website title
In Chicago Author-Date, the year belongs immediately after the first element of the reference, not later in the entry.
Wrong
✕ “Campus Cooling Center Locations.” City Resilience Office. 2025. June 18. https://www.cityresilience.gov/cooling-centers.
Correct
✓ “Campus Cooling Center Locations.” 2025. City Resilience Office. June 18. https://www.cityresilience.gov/cooling-centers.
Styling the entry like APA or MLA
Chicago Author-Date does not use the APA italic title-first pattern. It keeps the webpage title in quotation marks and, when a website title is included, italicizes that website title as a separate element.
Wrong
✕Campus Cooling Center Locations. (2025). City Resilience Office. https://www.cityresilience.gov/cooling-centers
Correct
✓ “Campus Cooling Center Locations.” 2025. City Resilience Office. June 18. https://www.cityresilience.gov/cooling-centers.
Leaving the year slot blank on an undated page
Chicago Author-Date keeps the year position visible. When no date is available, use n.d. rather than skipping the year entirely.
Wrong
✕ “Neighborhood Air-Quality Dashboard.” Regional Data Hub. Accessed March 13, 2026. https://www.regionaldatahub.org/air-quality-dashboard.
Correct
✓ “Neighborhood Air-Quality Dashboard.” n.d. Regional Data Hub. Accessed March 13, 2026. https://www.regionaldatahub.org/air-quality-dashboard.
Repeating the same organization as both author and website title
If the organization author and the website title are identical, repeating them both usually adds clutter without adding meaning.
Wrong
✕ Department of Water Resources. 2025. “Reservoir Conditions and Supply Outlook.” Department of Water Resources. May 14. https://www.dwr.gov/reservoir-conditions.
Correct
✓ Department of Water Resources. 2025. “Reservoir Conditions and Supply Outlook.” May 14. https://www.dwr.gov/reservoir-conditions.
