Have you signed up for RefWorks?

Refworks is a web-based citation management system offered free to UST students and faculty. It offers you a convenient and time-saving method of saving and formatting your citations. For help in setting up and using Refworks, view this video tutorial or ask a reference librarian

Note: Although Refworks is an efficient tool, its outputs must be carefully edited with the help of a style guide.


Shortened Citations in Notes

The second (or subsequent) time a resource is referenced, use a shortened form of the citation.  The short form should include the last name of the author, a brief form of the title (three to four words), and the page number.  For example:

      95. Miller, Quest, 81.

If the resource is cited a second time immediately following a citation (full or shortened) then use ibid.  If the page number referenced is the same, no page number is needed.  If a different page number is referenced, ibid. should be followed by the page number.  For example:

     5. Farmwinkle, Humor of the Midwest, 241.

     6. Ibid., 258-59.

     7. Ibid.

     8. Ibid., 333-34.



About Chicago Style

This guide summarizes the information found in the 16th edition of the Chicago Manual of Style

The Chicago Manual of Style offers two distinct documentation methods, one for the humanities (Notes and Bibliography system) and one for the sciences (Author-Date system).  This guide will focus only on the Notes and Bibliography style, which is commonly used for documentation in history, art history, theology, and many other humanities-based subjects.

The humanities documentation method uses notes (footnotes or endnotes) and a bibliography. 

The Chicago Manual of Style is available online here.

 For additional help with writing and citation, contact the Tutorial Services Center.
