The Chicago Manual of Style allows for two versions of references: in-text, author-date citations plus bibliography; or footnotes or endnotes, which in turn can be either "short" notes, which require a bibliography, or "full" notes, which do not. You should confirm which style to use with your instructor.  

Here is an example of the main differences: 

Author-date style: 

  • Here is an example of an author-date in-text citation for pages 34-35 of Graham Allison's book, Essence of decision: explaining the Cuban Missile Crisis: 

(Allison 1999: 34–35) 

  • If you choose (author-date), you must include a bibliography at the end of your paper. Here is the example of that entry:

Allison, Graham T. 1999. Essence of Decision: Explaining the Cuban Missile Crisis. 2nd ed. New York: Longman.

Footnotes or endnotes: 

  • Full note provides more information about the source and is often used in shorter papers for which you will not include a bibliography at the end of the paper. Here is an example full note for citing pages 34-35 of Graham Allison's book, Essence of decision: explaining the Cuban Missile Crisis:

Graham T. Allison, Essence of Decision: Explaining the Cuban Missile Crisis, 2nd ed. (New York: Longman, 1999), 34–35.

  • A (short) note for the same citation would look like this:

Allison, Essence of Decision, 34–35.

  • When using short notes, you must include a bibliography at the end of your paper. The entry for this book would like this (note that is ordered slightly differently from the bibliography for author-date style):

Allison, Graham T. Essence of Decision: Explaining the Cuban Missile Crisis. 2nd ed. New York:  Longman, 1999.

 

If you wish to include footnotes or endnotes in your paper, you must choose either (full note) or (note) from the Citation Style menu and then also choose whether you want Zotero to populate those citations at the end of each page (Footnotes) or at the end of your document (Endnotes).
