Notes are the equivalent to in-text citations used in MLA and APA format.  However, notes require much more detail.  

In Chicago format, citations following these steps:

1. Indicate a citation by adding a superscript number next to the text; (in the video below, we'll show you how to add a superscript)
2. List the citation information in footnote/endnote (depending upon what your professor asks for)
3. Include a bibliography at the end of your paper.  Always. 

1. Cole found that "The bones were very fragile" (33-34) ¹

The first time in-text reference is cited you must include, author's first name, author's last name, title, place of publication, publisher name, year, and pages used.  

Examples:  

1. James Smith, The First Last War, (New York, Hamilton, 2003), 2.  

But if you have cited, you can shorten your citation in your notes.  

2. Smith, The First, 22-23. 

And, you can always use Ibid

3. Ibid., 76.  

Smith, James. The First and Last Year of War.  New York: Hamilton Press, 2003.
