Citing Your Sources

_{^{*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. Here is an explanation of url issues from Chicago Manual of Style.
• 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!

• Purdue's Complete Discipline Listing
• Fiveable AP Research Guides

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.

SOURCES FROM THE INTERNET: WEBSITES, BLOGS, EMAILS, ONLINE VIDEOS

General information about formatting websites (CMOS, Section 14): 

• write titles of websites without quotation marks and capitalize first words except prepositions and conjunctions (no italics - unless the website is of a known publication, e.g. New York Times).
• titled sections of websites are in quotation marks
• titles of blogs are italicized and entries in blogs have quotes around them (blogs are treated like journals in this sense)
• If the site has a modification, publication, or revision date, put this information before the website url in your bibliography and in your first note
• name the website in the text so you can avoid a long footnote;("As of the year 2017, Google Privacy Policy had over x words..."). If you need a more formal citation to reference specific content from the site, use the examples below. Because online web content changes frequently, if there is an update or copyright date on the site, include it.

• The basic format for a website (from CMOS)

(N) “Title of Document/Webpage,” Title of the website, Author/Owner, last modified date or accessed date, URL.
(N) Author's last name, “Shortened title of Document/Webpage.” (If there is no author then put just the title of webpage/document. If you are citing a whole site and there is no author or webpage/document, just put the name of the site.)
(Bib) Author (and/or owner, sponsor). “Document/Webpage Title.” Title of Website. Updated or Accessed Date. URL.

• Websites

• Blog entry or comment

Blog entries or comments may be cited in running text ("In a comment posted to The Becker-Posner Blog on February 16, 2012, . . .") instead of in a note, and they are commonly omitted from a bibliography. The following examples show the more formal versions of the citations.

• E-mail or text message

E-mail and text messages may be cited in running text ("In a text message to the author on July 21, 2012, John Doe revealed . . .") instead of in a note, and they are rarely listed in a bibliography. The following example shows the more formal version of a note.

(N) 1. John Doe, e-mail message to author, July 21, 2012.

• Comment posted on a social networking service

Like e-mail and text messages, comments posted on a social networking service may be cited in running text instead of in a note, and they are rarely listed in a bibliography. The following example shows how to integrate the information into running text.

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.org. No 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. 

A Note for History Students: When citing your sources, ensure you always stay within the 17th Edition of CMOS until your teacher approves the 18th Edition. Here is how:

• Click on the Permalink to the 17th Edition of CMOS,
• DO NOT click on "Citation Quick Guide" or  "CMOS18."  (at the top of the page) Clicking on any of these two links will take you out of the 17th Edition (pages have a blue and red banner).
• If you find yourself in the 18th Edition (grey banner, green nav bar), look for a link to CMOS 17 in the banner at the top of the page, or close and reopen the page.

The screenshot below shows you what the 17ths Edition looks like, and which links to NOT click on.  

Having Difficulty?  Talk to your Teacher or Librarian if you need more help with the online version of CMOS.  Alternatively, to ensure you always stay within the 17th Edition when citing your sources, you can always use our beginner's guide to CMOS or the curated websites in the box titled "Selected formats for Sources from Chicago."

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.

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 17 no longer requires an access date for 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 generator, zbib.org, that supports CMS 17th edition. No citation generator is perfect and you should always check your work.

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)

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 most current APA Manual is the 7th edition.

• Look at Purdue University APA Guide website including examples and explanations of in text citations and reference lists. Purdue OWL APA Style also has sample papers.
• Check the many free resources on the APA website including examples and explanations of in text citations and reference lists (scroll down for examples).<

• Ask for the Publication Manual of the American Psychological Association by American Psychological Association Staff, Call Number: REF 808 PUB, at the USIC desk.

   

The American Mathematical Society has a mathematics style guide that uses a numbering system.  Read about AMS and download the guide (large PDF) on the AMS site. There is no print version of this guide in the library, but the full guide (PDF) is online.

The American Institute of Physics has a style guide that is used mainly for physics. The information on this site is helpful. There is not a print guide, but there is a full version of the guide (pdf) online. Your teacher will tell you if you need to use this guide.

The American Chemical Society has a guide for chemistry research papers. You can find some information on the ACS site. Use this guide fro papers specifically about chemistry.

For research papers in science, students may use the Scientific Style and Format: The CSE Manual for Authors, Editors, and Publishers. There is a helpful online guide from the CSE as well as a Dalhousie university guide that has up-to-date information as of March 2022.

This Student Guide is created by AI for Education to help you decide when it is appropriate to use AI for a project or homework.  The section "Yes, but" tells you when AI can be a useful research tool. Always consult your teacher before using AI so as to ensure it helps you meet your learning goals.  Page updated March 6, 2024

Below is some information on how to cite AI. Most style guides have sites with information on citing AI. (Google the style guide and the words AI or ChatGPT.)

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.
