Core Chicago author-date rules

Reference list entries are alphabetized by author and use a hanging indent in manuscripts. Article titles appear in title case inside quotation marks; book and journal titles are italicized. Dates follow month-day-year order in the reference list when a full date is given (May 14, 2024). In-text citations place the author and year in parentheses and add page numbers after a comma when quoting or citing a specific passage: (Okoro 2022, 88).

Step-by-step: citing common sources in Chicago

1. Books:Invert the first author's name, place the year after the author, italicize the title, and list the publisher. Include the place of publication when your local Chicago guidance still requires it.
2. Journal articles: Put the year after the author, enclose the article title in quotation marks, italicize the journal, and provide volume, issue, and pages. Prefer a DOI expressed as a full URL.
3. Websites: Credit the author or owning organization, include the year and a more specific date when known, quote the page title, name the website, and finish with the URL. If dates are missing, Chicago allows n.d. and may recommend an access date for undated or frequently updated pages.
4. Digital media: Cite the creator, year, title, platform or publisher, full date of posting when available, and URL. Describe the medium in the text of your paper if readers need extra context.

Chicago FAQs

In-text citations vs. bibliography / reference list

Author-date Chicago uses brief parenthetical citations in the text and a matching reference list. Notes-bibliography Chicago instead uses footnotes or endnotes plus a bibliography; CiteLite does not auto-generate footnote marks, so if your course requires notes, convert the reference data into note form using the Manual. Never mix systems in one paper unless an editor explicitly allows it.

DOI formatting

Chicago prefers DOIs over database URLs. Write them as https://doi.org/ followed by the DOI suffix, without a terminal period that could break the link. If no DOI exists, a stable URL is acceptable for online sources.

Author conventions and Harvard comparisons

List the first author inverted (Surname, Given Name) and subsequent authors in direct order, separated by commas, with “and” before the final name. For four or more authors, Chicago author-date often keeps up to a certain number in the reference list and may use et al. in-text—confirm the threshold in CMOS 17 or your style sheet. Harvard referencing, common at UK and Australian universities, also uses author-date citations; punctuation, ampersand use, and page abbreviations (p./pp.) vary by institution. If you are asked for Harvard, start from Chicago author-date output and adjust to your university's Harvard guide.

Using the CiteLite Chicago generator

Select Chicago 17 in the tool, enter source details once, and review the full reference alongside parenthetical and narrative citations. Assemble a session reference list, export it, and proofread italics, dates, and DOIs. Chicago has many edge cases—classical works, secondary citations, and manuscript collections among them—so unusual sources should be checked in the Manual. CiteLite keeps the routine cases fast and free of video ads while you remain the final authority on compliance.
