The Chicago Manual of Style
by
Call Number: Georgetown Downtown Reserves ; Z253 .U69 2024ISBN: 9780226817972Publication Date: 2024-09-19The venerable, time-tested guide to style, usage, and grammar--an indispensable reference informing the editorial canon with sound, definitive advice. Now in its 18th edition! More than 1.75 million copies sold! Much has happened in the years since the publication of the seventeenth edition of The Chicago Manual of Style. The world has transformed, and the Manual has risen to meet the moment. The eighteenth edition of this classic guide for writers, editors, and publishers is the most extensive revision in two decades. Every chapter has been reexamined with diversity and accessibility in mind, and major changes include updated and expanded coverage of pronoun use and inclusive language, revised guidelines on capitalization, a broader range of examples, new coverage of Indigenous languages, and expanded advice on making publications accessible to people with disabilities. The Manual's traditional focus on nonfiction has been expanded to include fiction and other creative genres in coverage of topics such as punctuation and dialogue, and the needs of self-published authors receive wider attention. The citation chapters have been thoroughly reorganized for the benefit of new and experienced users alike, and the key concepts for editing mathematics have been integrated into the chapters where they will be most useful to generalists. Evolving technologies--from open-access publishing models to AI--are covered throughout. And naturally, there are some well-considered updates to familiar rules, including changes intended to align the Manual's recommendations more closely with real-world usage. As with every new edition, devotees of the Manual will find much to discover and ponder. -

Specific Examples
Common Citation Examples:
In-Direct Sources:
Because authors are generally expected to be intimately familiar with the sources they are citing, Chicago discourages the use of a source that was cited within another (secondary) source. In the case that an original source is utterly unavailable, however, Chicago recommends the use of "quoted in" for the note:
Note Citation:
7. Ian Hacking, The Social Construction of What? (Cambridge, MA: Harvard University Press, 1999), 103, quoted in Manuel DeLanda, A New Philosophy of Society (New York: Continuum, 2006), 2.

Citing Information Generated by ChatGPT/AI
Ask your program about their guidelines for incorporating information generated by ChatGPT and other AI in your papers. When permissible to utilize AI, use the suggestions below.
The newly issued 18th edition of the Chicago Manual of Style provides guidelines for citing AI-generated content in Section 14.112. To ethically incorporate the information product generated by ChatGPT or other AI, the Manual’s recommendation is to cite “[a]ny specific content, whether quoted or paraphrased,...where it occurs, either in the text or in a note. Like personal communications (see 14.111) and social media posts (see 14.106), chatbot conversations are not usually included in a bibliography or reference list.” The specific information to include in the text or in the note when citing AI-generated content is as follows:
-
The prompt you used when utilizing ChatGPT or other AI;
-
The AI software used to create the content (e.g., ChatGPT) and the software’s publisher or developer (e.g., OpenAI);
-
The date when the content was generated;
-
The URL (if available) of a publicly archived copy of the conversation;
In-text example:
The following definition of a multi-site case study comparison method was generated on September 9, 2024, by ChatGPT-4o, using the prompt “Explain what is a multi-site case study comparison method using recent published examples."
Note example:
1. Response to “Explain what is a multi-site case study comparison method using recent published examples," ChatGPT-4o, OpenAI, September 9, 2024, https://chat.openai.com/share/90b8137d-ff1c-4c0c-b123-2868623c4am4.
Please note that similar guidelines apply to citing an image created by/with the help of AI (see 3.38):
In-text example:
Fig. 3. Image generated by ChatGPT-4o, September 12, 2024, from the prompt “Create an image of libraries in France.”
Please also remember that if AI connects you to another resource, you need to cite that resource, just as you would in a literature review.
