Important Info about Citing

*For information on how to cite ChatGPT & other AI, go to the left navigation bar and click on the last link

Download sources as you find them! Important notes about URLS:

  • Include urls as required by your ciation system for online sources but always download the item as URLs do not always work
  • Use the doi as a url for a journal article when possible (doi = unique identifying # for the article) - e.g. https://doi.org/10.1186/s12889-021-10770-4.

  • The urls from our USIC search will not work. IF you have only the url, you'll have to find the document again by searching the highlighted part only from the url in our USIC search. There is not always an AN # though, so download. 

Below are styles and basic outlines of their disciplines. Your teacher might require you to use a different citation styles for the disciplines below.

Chicago/CMOS

  • History, Business, Fine Arts

MLA

  • Literature, World Languages, Film, Performing Arts 

APA

  • Psychology, Social Sciences

Comparison of APA, MLA, and CMOS.

TAS teachers might also require using one of the below systems. 

  • AMS - Mathematics from the Amer. Mathematical Society
  • ACS - Chemistry from the  Amer. Chemical Society
  • AIP - Physics from the Amer. Institute of Physics.
  • CSE  -  Science from the Council of Science Editors

For more information on which styles to use when, check the resources below, which have also been consulted to update this page. Remember:  If your teacher tells you to use a particular style guide, that is the guide you should use!

Rules for Citation Success
  • Record your source as soon as you find it! It can be difficult to go back and find a source again.
  • Always follow the guidelines that your teacher gives even if they differ slightly from the citation rules. 
  • Have open an online or hard copy of the citation guide (Chicago, APA, MLA) while you are creating/fixing your citations.
  • Always proofread when using a citation generator or database-generated citation before handing in your assignment. Generators and databases make mistakes.
  • Citations have rules. Follow them consistently. Citations follow a pattern so that readers can easily recognize where to find the research you’ve used.
  • Do NOT leave proofing your citations until the last minute. You need time to review as detail requires focus.
  • For your own reference, do not rely on a URL to revisit your source. Record the database/website name as well as the author and title information even before formatting your citation. 
How to Find Citation Information in a Print Book

On the back of the title page of a book, there is a page called the verso page. This page has information needed for your citation and, usually, an ISBN (which is handy if you are using Zotero). Please see the image below for an example of the information found on a verso page.

FAQ'S OF CITING IN CMOS

How do I find my article again?

  • Download the full text of the article/book, if available, AND grab the full citation and permalink from your database. Using permalinks can be confusing. Ask the librarians in USIC if you have an issue finding an article again. 

Do I need an access date?

  • Maybe. Chicago Manual of Style no longer requires an access date for all online sources, but some databases and citation generators (NoodleTools, Zotero) still insert an access date. It is not wrong Academic sources including online journals and encyclopedias do not need access dates.

Do I need a url at the end of my citation?

Yes. Some online citations from databases including Google Scholar do not include the url. Copy the url or DOI (a url specific to a journal article) and place it after the last period in your citation. Put a period after the url. 

What is the difference between a bibliography entry and notes?

  • On this page the (Bib) means bibliography and this includes the most information as it appears on your bibliography page. Readers will go here for the complete information about your source. How to create an annotated bibliography.
  • (N) means note. Your first footnote for a citation is longer than your second. Find more examples of bibs and notes in the Chicago manual itself.  

What if my eBook or online article doesn't have specific page #s?

If no fixed page numbers are available, cite a section title or a chapter or other number in the notes, if any (or simply omit).

(1st N) Philip B. Kurland and Ralph Lerner, eds., The Founders’ Constitution (Chicago: University of Chicago Press, 1987), chap. 10, doc. 19, http://press-pubs.uchicago.edu/founders/.

(1st N) Jane Austen, Pride and Prejudice (New York: Penguin Classics, 2007), chap. 3, Kindle.

(2nd N) Kurland and Lerner, Founders’ Constitution, chap. 4, doc. 29.

(2nd N) Austen, Pride and Prejudice, chap. 14.

Do I put the country or state or just the city of a source in my bibliography?

Chicago requires only the city. You may put the abbreviation for a state or a country if the city exists in multiple places in the world.

I want to use a citation generator - any suggestions? 

Zotero has an easy online citation generator, zbib.orgNo citation generator is perfect. Proof your citations. 

When using the zbib.org the first time:

  • put in your ISBN or title first (or url, etc.)
  • once you have a citation choose your citation style
  • choose Chicago Manual of Style 17th edition Note and Bibliography (you might have to search the word Chicago)

Where is the citation information located in a print book?

On the back of the title page of a book, there is a page called the verso page. This page has information needed for your citation and, usually, an ISBN (which is handy if you are using Zotero). Please see the image below for an example of the information found on a verso or cip (cataloging-in-publication) page.

Sources:  

Citations on this page are either taken from the CMOS Guide or created by your eLibrarian from the results of searches conducted on the Library's Single Search box. 

Selected Formats for Sources from Chicago

Below are examples that link directly to the Chicago Manual of Style (CMOS). Owl Purdue CMOS site also has good examples.

How to Find Citation Information from a Print Book

On the back of the title page of a book, there is a page called the verso page. This page has information needed for your citation and, usually, an ISBN (which is handy if you are using Zotero). Please see the image below for an example of the information found on a verso page.

Citing Primary Sources

Open the Chicago Manual of Style (CMOS) first and then use the links below. If possible, cite from the website of the institution that holds the source if it is a digitized item. If you find the item in a secondary source, and not on an institution's website, there is an example below. Please note that the (Bib) entry is for your bibliography, and that is not possible to do hanging indents on this page - you'll need an indent in all lines after the first for each item in your bibliography.

Citation Generators and Database Generated Citations

Always download the full article or book, if you can, and copy or export the full citation. URLS and permalinks might not work.

A note on citing online sources: Chicago Manual of Style no longer requires an access date or online sources, but some databases still insert it their generated citations that's fine as long as you consistently insert them in your other citations. Just be consistent in how, when, and if you use an accessed date. It can be confusing to figure out what format is correct for online sources, but do your best and stay consistent.

Zotero

Zotero has an easy online generatorzbib.org, that supports CMS 17th edition. No citation generator is perfect and you should always check your work against the Chicago Manual.

When using the zbib.org the first time:

  • put in your ISBN or title first into the box
  • once you have a citation choose your citation style
  • choose Chicago Manual of Style 17th edition Note or Chicago Manual of Style 17th edition Note and Bibliography (you might have to search the word Chicago)

 

Using the Chicago Manual of Style, 17th edition Online

Chicago Manual of Style (CMOS) has two methods for citation. TAS uses the Notes and Bibliography (NB) style and not Author-DateSection 14 of Part III, and the NB section of the Citation Quick Guide have examples of bibliography as well as note and shortened note formats for citations. For the majority of your citations, especially as a beginning researcher, you will find the information you need in the Citation Quick Guide or on this webpage. If you have questions about more complex citations, ask us or search the CMOS

Searching Chicago Manual of Style (CMOS) 

Topics are arranged by numbers. The numbers after the period represent different sections on the same topic (e.g.,14.1-14.37). Search for keywords like "video" or legal documents to find NB citation information (usually the number for NB begins with 14).

Bibliography and Footnote Formatting

A bibliography is a list of your sources on a page at the end of your paper. The sources are listed in alphabetical order by the author's last name. Alphabetize by the title of the work if there is no author. Omit articles (the, a, and) when alphabetizing titles.

TAS uses footnotes instead of endnotes. Footnotes appear at the bottom of each page. The footnote format changes the second time you cite the source and thereafter.

  • Use the full longer note style when citing a source for the first time in your paper.
  • Use the shortened note style citing a source for the second time and thereafter.
MLA

MLA (Modern Language Association) 

MLA is used mainly for literature research, but it can also be used for other disciplines. It's currently in its 9th edition.

  • Purdue OWL MLA Style has a description of the style plus examples of in text citations and works cited. Purdue takes its information from the 8th edition, which is fine as the latest edition, the 9th, adds more information to the 8th but does not change the citation style. For information on the difference between the 8th and 9th editions, see Purdue University's page.
  • MLA Handbook,  9th ed., is available in the library. Ask for the book at the circulation desk.

The FAQ's of Citing AI in Academic Research - A Guide by Chicago Manual of Style Online

 

Q. How do you recommend citing content developed or generated by artificial intelligence, such as ChatGPT? Many scholarly publishers are requiring its identification though also requiring human authors to take responsibility for it and will not permit the AI to have “authorship.”

A. You do need to credit ChatGPT and similar tools whenever you use the text that they generate in your own work. But for most types of writing, you can simply acknowledge the AI tool in your text (e.g., The following recipe for pizza dough was generated by ChatGPT).

If you need a more formal citation—for example, for a student paper or for a research article—a numbered footnote or endnote might look like this:

1. Text generated by ChatGPT, OpenAI, March 7, 2023, https://chat.openai.com/chat.

ChatGPT stands in as “author” of the content, and OpenAI (the company that developed ChatGPT) is the publisher or sponsor, followed by the date the text was generated. After that, the URL tells us where the ChatGPT tool may be found, but because readers can’t necessarily get to the cited content (see below), that URL isn’t an essential element of the citation.

Footnote:

1. ChatGPT, response to “Explain how to make pizza dough from common household ingredients,” OpenAI, March 7, 2023.

If you’ve edited the AI-generated text, you should say so in the text or at the end of the note (e.g., “edited for style and content”). But you don’t need to say, for example, that you’ve applied smart quotes or adjusted the font; changes like those can be imposed silently (see CMOS 13.7 and 13.8).

But don’t cite ChatGPT in a bibliography or reference list unless you provide a publicly available link (e.g., via a browser extension like ShareGPT or A.I. Archives). Though OpenAI assigns unique URLs to conversations generated from your prompts, those can’t be used by others to access the same content (they require your login credentials), making a ChatGPT conversation like an email, phone, or text conversation—or any other type of personal communication (see CMOS 14.214 and 15.53).

[Editor’s update: Original answer updated to put the publisher before the date and to acknowledge tools like ShareGPT and A.I. Archives.]

To sum things up, you must credit ChatGPT when you reproduce its words within your own work, but unless you include a publicly available URL, that information should be put in the text or in a note—not in a bibliography or reference list. Other AI-generated text can be cited similarly. 

Q. Robots are being named and even developing personalities, not just in fiction, but in the real world. Should their names be italicized—i.e., “I told Benjamin to wait at the coffee shop,” where Benjamin is a robot with artificial intelligence?

A. Italics for robot names could be fun in fiction; however, that doesn’t seem to be the convention either in fiction or in real life. (An exception is generally made for named spacecraft and the like, including the robotic Mars rover Perseverance; see CMOS 8.116.) Before you decide what to do, consider asking some robots to weigh in.

For some considerations on the use of AI in scholarly publishing and the responsibilities of authors, start with this position statement on authorship and AI tools from COPE (Committee on Publication Ethics).  Here is the Statement. It provides links to other useful sources.  

 

COPE position statement on Authorship and AI Tools: 

The use of artificial intelligence (AI) tools such as ChatGPT or Large Language Models in research publications is expanding rapidly. COPE joins organisations, such as WAME and the JAMA Network among others, to state that AI tools cannot be listed as an author of a paper.

AI tools cannot meet the requirements for authorship as they cannot take responsibility for the submitted work. As non-legal entities, they cannot assert the presence or absence of conflicts of interest nor manage copyright and license agreements.

Authors who use AI tools in the writing of a manuscript, production of images or graphical elements of the paper, or in the collection and analysis of data, must be transparent in disclosing in the Materials and Methods (or similar section) of the paper how the AI tool was used and which tool was used. Authors are fully responsible for the content of their manuscript, even those parts produced by an AI tool, and are thus liable for any breach of publication ethics.
