CITATION GENERATOR · CHICAGO

Chicago citation generator.

Paste a DOI to get a Chicago Manual of Style citation, 18th edition, in either of its two systems: author-date or notes and bibliography. Free, no account, and it runs in your browser.

Author-date or notes and bibliography

Chicago has two systems. Pick the one your instructor or publisher asks for in the style menu:

• Chicago (author-date) is common in the sciences and social sciences. You cite in the text by author and year, and list full references at the end.
• Chicago (notes), notes and bibliography, is common in history, literature and the arts. You cite in footnotes or endnotes, and usually add a bibliography too.

Chicago author-date

LeCun, Yann, Yoshua Bengio, and Geoffrey Hinton. 2015. “Deep Learning.” Nature 521 (7553): 436–44. https://doi.org/10.1038/nature14539.

The in-text citation has no comma between author and year: (LeCun et al. 2015), or (LeCun et al. 2015, 437) with the page you are citing, which you add yourself.

Chicago notes and bibliography

The first note to a work gives its full details:

Yann LeCun et al., “Deep Learning,” Nature 521, no. 7553 (2015): 436–44, https://doi.org/10.1038/nature14539.

The bibliography entry reverses the first author’s name and uses full stops between parts:

LeCun, Yann, Yoshua Bengio, and Geoffrey Hinton. “Deep Learning.” Nature 521, no. 7553 (2015): 436–44. https://doi.org/10.1038/nature14539.

Later notes to the same work can be shortened to the author’s surname, a short title and the page. The tool shows the full first note; replace its page range with the page you are citing.

What to check

Both systems are built from what the publisher registered for the DOI. Chicago uses title case, applied automatically, so read titles with names, acronyms or formulas once. Add any missing issue or page numbers from the article itself.

Need another style? The same tool does APA, MLA, Harvard, IEEE, Vancouver and more, and BibTeX for LaTeX.

Keep your references in a library

Docr’d is a research library for papers, books and standards. It keeps your PDFs, notes and highlights together, and copies citations in both Chicago systems and twelve other styles, or as BibTeX and RIS. The desktop apps for macOS, Windows and Linux are free to use without an account. Docr’d is in early access, so you may run into rough edges.
