Citing Sources: CHICAGO EXAMPLES

In-Text Example:

Chicago does not require a citation for content generated by ChatGPT and other AI tools.  Mentioning it as the source of content within your work is enough; for example: ChatGPT created the following poem.

Your professor may still require a citation. Use only a footnote, not a bibliography citation, treating the AI tool as the author.

Footnote Example:

1. ChatGPT, response to “Describe a rose in 2 paragraphs,” OpenAI, September 26, 2023, chat.openai.com/chat.

1. AI Tool Name, response to “Full Text of Prompt,” Company Name, Date of Prompt, URL.

The Chicago-Style Citation Quick Guide on the Chicago Manual of Style website provides excellent examples of common citation entries in both the notes and bibliography and author/date formats. Click on the link to access the Quick Guide.

 Chicago style citation follows two separate formats: 1. notes and bibliography and 2. author-date. Be sure to ask your professor which format they prefer. 

• In the notes and bibliography format, sources are cited in the text by including a superscript number¹ next to the quotation, paraphrase, or source reference. The full citation is then listed in a note, either as a footnote (at the bottom of the page) or as an endnote (at the end of the chapter or article). A bibliography, or separate list of sources, is often, but not always, included. Ask your professor about their preferences regarding footnotes, endnotes, and the bibliography. For more information, see also Chapter 14 in The Chicago Manual of Style.

• In the author-date format, sources are cited in the text by including the author's last name and the year of publication in parentheses directly following the quotation, paraphrase, or other source reference. Page numbers are included for quotations and some paraphrased materials. Example: (Jones 2003) or (Jones 2003, 45). A References list with full citations is required at the end of the document. For more information, see also Chapter 15 in The Chicago Manual of Style.

If you choose to use AI tools in your research or writing process, you should:

• Cite a generative AI tool whenever you paraphrase, quote, or incorporate into your own work any content (whether text, image, data, or other) that was created by it.
• Acknowledge all functional uses of the tool (like editing your prose or translating words) in a note, your text, or another suitable location.
• If it is citing some other source, click through to see and vet the secondary sources it cites.

You should also check your course syllabus or talk to your professor to make sure you are following their guidelines and requirements for the class.
