Chicago Citation Generator

Surname, First Name, and First Name Surname. Year. “Title of Article.” Journal Title Volume (Issue): first–last. https://doi.org/10.xxxx/xxxxx.

• Authors: the first author inverted (Krejcie, Robert V.), the others in normal order, with full first names as published.
• Year: right after the authors.
• Title: in headline-style capitalization and double quotation marks, with the period inside.
• Journal: the full title in italics, followed by volume, issue and pages.
• DOI: as a https://doi.org/ link at the end.

These are the generator’s own results for real articles, copied on November 1, 2026. Paste the same DOI above to reproduce them.

Give the surname and year in parentheses, with no comma between them, and a page number after a comma when you cite a passage. With three or more authors, cite the first author followed by et al.

Sample sizes can be read from a table (Krejcie and Morgan 1970, 608).

Array programming made numerical Python practical (Harris et al. 2020).

• Title the list References and order it alphabetically by the first author’s surname.
• Copied text loses italics. Set the journal title in italics after you paste the reference.
• With seven or more authors, the reference lists the first three followed by et al., the rule of the 18th edition (2024).
• Give the full journal title, not an abbreviation, and the page range of the whole article.
• Only the author-date system is generated here. For notes and bibliography, rearrange the reference as shown above.

Chicago format for a book

Surname, First Name. Year. Title of Book. Place of publication: Publisher.

The book title is in italics. The 18th edition makes the place of publication optional. Books and chapters that have a DOI can be pasted into the generator.

Does this generator make Chicago notes and bibliography citations?

No, it makes author-date references, the Chicago system used in the sciences and social sciences. A notes and bibliography entry has the same parts in a different order: the year moves after the volume and issue, as in Journal 30, no. 3 (1970): 607–10. The example on this page shows the conversion.

Which edition of the Chicago Manual of Style is used?

The reference follows the Citation Style Language definition of Chicago author-date. Its author list matches the 18th edition, published in 2024: with seven or more authors, the first three are listed and followed by et al.

How do I write a Chicago author-date in-text citation?

Put the author’s surname and the year in parentheses with no comma between them, such as (Krejcie and Morgan 1970). Add a page after a comma when you cite a specific passage: (Krejcie and Morgan 1970, 608). With three or more authors, use the first author and et al.

Can I make a Chicago citation from a PubMed ID?

Yes, when the PubMed article has a DOI: the reference is built from the DOI record. A PubMed article without a DOI cannot be formatted in Chicago style here, because the National Library of Medicine’s exporter only offers APA, AMA, MLA and NLM.
