    Chicago 18th edition (notes and bibliography) citations, formatted from the source record

    Paste a DOI, an ISBN, a link or a title and the tool finds the publisher's own record for it and formats it in Chicago 18th edition (notes and bibliography) — the notes system used in history, art history, classics, theology, philosophy and much of publishing. The bibliography entry and the footnote come together, and the rules are those of the The Chicago Manual of Style, 18th edition (2024), published by the University of Chicago Press. The 18th edition was published in September 2024; the 17th (2017) is still widely in use and is also in the style picker.

    The manual's Q&A and the Chicago-Style Citation Quick Guide at chicagomanualofstyle.org show the note and bibliography forms side by side for each source type.

    How to cite in Chicago here

    Three steps, about twenty seconds a source.

    1

    Paste what you have

    A DOI, an ISBN, a PubMed or arXiv ID, a web address, or a title. Chicago is already selected on this page. The tool works out what you pasted and asks the right catalogue — Crossref, OpenLibrary, PubMed, DataCite or Semantic Scholar — for the record.

    2

    Read the card

    Each source gets a card showing what the catalogue held and what the tool changed to fit Chicago: a DOI reduced to its bare form, a page range tidied. Every change can be undone with one click if the record was right as it was.

    3

    Take the finished list

    Copy the list with its formatting into Word or Google Docs, or download a .docx with the hanging indent and spacing already set. BibTeX, RIS and CSL-JSON exports carry the same data into Zotero, Mendeley, EndNote or LaTeX.

    How Chicago formats a citation

    The rules the tool applies, from the The Chicago Manual of Style, 18th edition (2024).

    • In the footnotesA superscript number in the text, and a footnote or endnote with the same number carrying the citation. The first note for a source is the full citation; later notes for the same source are shortened to the author's surname, a short title, and the page. The note gives names in natural order, Thomas S. Kuhn, separates elements with commas, and puts the publication details in parentheses: Thomas S. Kuhn, The Structure of Scientific Revolutions, 4th ed. (University of Chicago Press, 2012), 12.
    • The bibliographyA Bibliography at the end, alphabetical by the first author's surname, with a hanging indent. A bibliography entry separates its elements with periods, inverts the first author's name, and gives the full page range of an article rather than the page cited.
    • Author namesIn the bibliography the first author is inverted, Golder, Scott A., and any further authors are in normal order, joined by and. In a note all names are in normal order. A work with four or more authors is cited in a note by the first author and et al.
    • Titles and capitalsTitle case: principal words capitalised. Books, journals and websites are italic; articles, chapters and web pages are in quotation marks. A journal article gives volume, issue and year: Science 333, no. 6051 (2011).
    • DatesThe year in parentheses after the volume and issue for a journal, and after the publisher for a book. A web page carries its full date, Month Day, Year, and an access date only when there is no publication date.
    • Links, identifiers and placesA DOI is written as a link, https://doi.org/…, and ends the entry with a period; otherwise the URL. The 18th edition no longer asks for the publisher's place, so a book is University of Chicago Press, 2012, with no city in front of it.

    Chicago 18th edition (notes and bibliography) examples, printed by the tool

    Six real sources — two journal articles, a book, a chapter, a web page and a conference paper — formatted by the same engine that runs the generator above. Nothing here was typed by hand, so what you see is what you get.

    Common mistakes in Chicago citations

    Five errors markers see most often, and what the tool does about each.

    Parentheses in a footnote paper

    Chicago has two systems. If your department wants notes and bibliography, an in-text (Kuhn 2012, 12) is the author–date system and will be marked as the wrong one. The author–date variant has its own page.

    Chicago: in front of the publisher

    The place of publication was dropped in the 18th edition. Older guides and generators still print it.

    Ibid. for the previous note

    Since the 17th edition the manual prefers a shortened citation — Kuhn, Structure, 14 — to ibid., and the tool prints shortened forms.

    Notes formatted like bibliography entries

    A note uses commas and natural name order; a bibliography entry uses periods and inverts the first name. Copying one form into the other is the commonest Chicago error.

    p. before a page number

    Chicago gives the bare number: (University of Chicago Press, 2012), 12. Neither notes nor the bibliography use p. or pp.

    Chicago beside the styles it is confused with

    If your handbook names one of these instead, its page opens the generator with that style selected.

    Chicago and Chicago Author–Date

    Same manual, different system: the citation goes in parentheses as (Kuhn 2012, 12), and the reference list moves the year to just after the author. Sciences and social sciences that use Chicago usually use this one. Open the Chicago Author–Date page.

    Chicago and MLA

    MLA also serves the humanities but cites in parentheses by page, with no notes and no year in the text. Open the MLA page.

    Chicago citation generator FAQs

    Is the Chicago citation generator free?

    Yes. Every style, every source type and every export is free, with no account and no daily allowance, because the formatting runs in your browser rather than on our servers. Your list is saved in this browser and never sent to us.

    Which edition of Chicago does it use?

    The 18th edition (2024) is the default here. The 17th edition, which some departments have not yet moved from, is in the style picker as Chicago Manual of Style 17th edition (notes and bibliography); the visible differences are the publisher's place, which the 17th still gives, and a few rules on capitalisation.

    What does an in-text citation look like in Chicago?

    Chicago cites in footnotes rather than in parentheses. A superscript number in the text, and a footnote or endnote with the same number carrying the citation. The tool prints the full footnote under each entry in the bibliography pane, and the export keeps it.

    How do I cite a website in Chicago?

    Paste the address and the tool reads the page's title, author, site name and date where the page declares them, then formats it. The Chicago form of a web page with an organisation as author and no date is: AI Writing Assistant. “Free AI Writing Tools: What Each Does and When to Use It.” AI Writing Assistant. Accessed September 18, 2026. https://www.aiwritingassistant.net/tools.html. Check the author and date on the card — pages often leave them out, and the style has a rule for each case.

    Can I switch from Chicago to another style later?

    Yes. Your sources are stored as data, not as formatted text, so choosing another style in the picker re-formats the whole list at once — APA, MLA, Chicago, Harvard, IEEE, Vancouver, or any of the 10,000 Citation Style Language styles the picker searches.

    Where do the Chicago rules come from?

    From the The Chicago Manual of Style, 18th edition (2024), published by the University of Chicago Press, as encoded in the open Citation Style Language style the tool uses. The manual's Q&A and the Chicago-Style Citation Quick Guide at chicagomanualofstyle.org show the note and bibliography forms side by side for each source type. Where your department's own guide differs on a detail, the department's guide is the one your marker reads.

    After the reference list

    Check the essay's grammar, tighten the wording, or summarise a source before you cite it. One plan covers every tool.
