    Questions

    Citations are formatted by citeproc-js by Frank Bennett (CPAL-1.0, or AGPL-1.0), the engine behind Zotero and Mendeley, running the official Citation Style Language styles (10,863 styles, commit 2e93558) and locales (commit a89adec), used under CC BY-SA 3.0. AGLC4 citations use the LexIntellect AGLC4 engine, checked against the Guide's worked examples. Always check a citation against the manual or your institution's guide before you submit.

    Which edition of Chicago author-date does this follow?

    Chicago 18th edition (author-date): 18th edition (2024), formatted from the chicago-author-date style in the Citation Style Language repository. It matches 7 reference examples from The Chicago Manual of Style character for character. Another 1 differ (web page), so check those source types against the manual.

    Who uses Chicago author-date?

    The physical, natural and social sciences.

    Is the Chicago author-date generator free?

    Yes. No account, no limit, and every export (Word, BibTeX, RIS, CSL-JSON) is included. Your list stays in your browser.

    Where do the details come from when I paste a DOI or link?

    DOIs come from Crossref and DataCite, ISBNs from Open Library and Google Books, PubMed IDs from NCBI, arXiv IDs from arXiv, YouTube links from YouTube, and web pages from the citation metadata the publisher embeds in the page (the same tags Google Scholar reads). Pages that carry no metadata are filled in as far as possible and the gaps are flagged for you.

    Can I export to Word, Zotero, EndNote or LaTeX?

    Yes. Copy the list with its italics into Word or Google Docs, download a formatted .docx, or export BibTeX for LaTeX, RIS for EndNote, Zotero and Mendeley, or CSL-JSON.

    How do I cite a quote from a video or lecture?

    Add the timestamp in the pinpoint box and paste the quote: the generator formats both for your style. To find the exact wording and the time it was said, get the full transcript of the video with timestamps first.
