Use the citation style required by your instructor, publisher, or project, then cite the specific online page, digitized object, or archived version that supports your claim—not merely the site’s homepage. Chicago offers useful models for history writing, but it is an example, not a universal requirement.
Start with the required citation style
Check the assignment, journal, publisher, or project guidelines first. If they specify a system, use its rules and source-specific examples. Chicago is often useful for history work because it provides both Notes and Bibliography and Author-Date guidance, but the Library of Congress (LOC) examples are guides to common formats in its digital collections, not a rule that every history paper must use Chicago.

Chicago’s official Notes and Bibliography Style guide shows models for online sources. The LOC offers Chicago examples for citing primary sources and a broader guide to citing primary sources. Follow the model that matches the material you used rather than squeezing every source into a generic website citation.

Identify exactly what you consulted
A useful citation gives readers enough information to find the same source and distinguish it from related material. Capture the creator or author, the page or item title, the responsible site or collection, the publication or revision date when available, and the URL or stable repository identifier required by your style. Cite the particular page that supports the claim; a homepage is not normally a bibliographic source when a specific page is available.

Also distinguish the historical object from the modern web page presenting it. A scanned photograph, letter, manual, or document is the primary source; the page that hosts the scan supplies repository and collection context. Retain the object’s own identifying details as well as the collection information requested by the citation model.
Choose the citation approach for the source
A current born-digital page
For a web page created for online publication, use the citation model for a webpage or online article in your required style. Include an author or responsible organization if identified, the page title, site name, date, and direct page URL where the style calls for them. If the page has no publication or revision date, Chicago’s guidance calls for an access date.
A digitized historical primary source
For an online scan or digital reproduction, use the model for the underlying object type—such as a photograph, letter, or document—and preserve its identifying details. Include the repository or collection context shown in the relevant style example so readers can locate the source beyond the page that displays it. The LOC’s primary-source citation examples cover common digitized material types in Chicago and MLA.

If an archived version is publicly available and it is the version you relied on, cite that version rather than silently substituting the live page. This makes clear which wording, data, or interface your claim depends on. Chicago’s online guidance addresses citing archived web versions.
For material in the Library of Congress Web Archives, LOC says the citation should indicate that it is “Archived in the Library of Congress Web Archives at www.loc.gov” and, when citing a particular website, include the archived website’s Citation ID, such as /item/lcwa00010240. Follow the LOC’s Web Archive research guide for the archive-specific details.
Make the citation reproducible
- Check the style rules. Confirm the required system and whether it uses notes and bibliography or author-date citations.
- Record the source’s identity. Save the creator, exact page or item title, site or collection name, date, and the direct URL or repository identifier specified by the style.
- Classify the material. Decide whether you used a born-digital page, a digitized historical object, or an archived web page; apply the matching model.
- Preserve version details. For an undated page, include an access date under Chicago guidance. If an archive is the version consulted, cite it and include any repository-specific identifier.
- Check that another reader can retrieve it. Verify that the citation points to the actual page or item, not just a homepage, and that the identifying details distinguish it from other versions.
Use official examples, not a guessed format
Chicago’s citation guide is the primary reference for its online-source conventions. For digitized material, compare your source with the LOC’s Chicago primary-source examples. If the item is from the Library of Congress Web Archives, use its archive citation guidance as well. NASA History’s Citation Guide is described as suggestions for Internet citations in history and historically based humanities; check your venue’s current rules before relying on it as the required format.
