How to cite in Chicago Manual of Style author-date
Create parenthetical author–date citations and a reference list. This is not Chicago notes and bibliography.
Citation software formats the information supplied to it; it cannot confirm that every field is complete or that a source is suitable for your work. Compare the output with the original source and the current instructions you must follow.
Use the selected source and style together
This Chicago page selects author–date, which pairs parenthetical markers with a reference list. It is a different system from Chicago notes and bibliography. The Kahneman example places the year near the beginning of the full reference so the author and date can be matched to the short citation. Choose the separate notes page if the assignment expects footnotes rather than converting the parentheses into footnotes yourself. Match the author and year in the short marker to the full reference entry. Add the passage locator required by your guide. Review works sharing an author and year together so their short citations remain distinguishable.
For the shared lookup and formatting walkthrough, see the citation generator guide. Keep this page’s edition and source-specific checks beside your output as you review it.
What to check
- Mixing author-date references with notes-and-bibliography footnotes
- Omitting a pinpoint page from a quotation’s parenthetical citation
Book example · Chicago author–date
In-text citation
(Kahneman 2011)
Full reference
Kahneman, Daniel. 2011. Thinking, Fast and Slow. Farrar, Straus and Giroux.
Book pattern checked against the Chicago author-date guide and pinned CSL file. Put the year after the author and italicize the title. A place of publication is no longer required. Add a locator for a passage, for example (Kahneman 2011, 24).
Check the official style guideSource fields for Chicago author-date
Check whether the work is a whole book, a chapter or an article before filling container fields. A whole book needs its publisher information; an article needs the journal and available volume, issue and pages. The catalog selection identifies the pinned author–date file; it should not be read as a claim that every department’s Chicago adaptation or every newer manual change is represented by that file.
Review Chicago author-date in your manuscript
Keep author spelling and publication year consistent between the reference and manuscript. Add the specific passage locator to the citation where required. If several works share an author and year, review their treatment together instead of assigning suffixes independently in isolated references. The full-list context matters when a reader must distinguish otherwise similar author–date markers.
Metadata and formatting
DOIs use Crossref, with DataCite when Crossref has no record; PMIDs use NCBI PubMed and ISBNs use Open Library. Public URLs use page metadata; YouTube oEmbed supplies title and channel, but no upload date. Pinned CSL styles format the records. No AI generates citation details, and PDFs are not uploaded or read here.
Frequently asked questions
Which Chicago system is this?
Author-date. Choose the Chicago notes page when your work calls for numbered notes and a bibliography.
How do I use the Chicago author-date reference in my writing?
Match the author and year in the short marker to the full reference entry. Add the passage locator required by your guide. Review works sharing an author and year together so their short citations remain distinguishable. Compare the final manuscript and reference list after edits; a correct isolated entry cannot establish that it is attached to the intended claim.
Can I enter Chicago author-date source details manually?
Yes. Select the actual source type and enter verified creators, title, date and publication details. For a book, check the edition and publisher; for an article, check the journal, volume and pages; for a website, use the specific page’s metadata. Manual entry changes the source record, not the rules of the selected style.
How should I enter a corporate author in Chicago author-date?
Enter an organization as a group author in braces, for example {World Health Organization}, so its words are not parsed as a person’s given name and surname. Keep individual authors in publication order. Check how the group’s name appears in the reference and the accompanying citation or note. Do not replace a credited individual with the website owner.
What if my Chicago author-date source has no publication date?
Leave an unknown date blank and let the pinned style handle missing information. Do not invent a year from a footer, file timestamp or the day you looked up the source. Check the publication before accepting a provider date, and keep access information separate. Review missing-date and title treatment against the exact edition or variant required for your document.
What does the Chicago author-date example demonstrate?
Book pattern checked against the Chicago author-date guide and pinned CSL file. Put the year after the author and italicize the title. A place of publication is no longer required. Add a locator for a passage, for example (Kahneman 2011, 24). The example is tied to the named source and pinned file; it does not demonstrate every source type or publisher override.
Is Chicago author-date free, and can I export BibTeX or RIS?
The first 3 sources are free per browser, shared across citation pages. Copy the formatted reference or export your saved bibliography as BibTeX or RIS. These files retain structured records for compatible tools; a destination can apply a different style. Check imported fields and keep a downloaded copy, since browser storage can be cleared and opening AnswerThis does not transfer this bibliography.
