Consult the Chicago Manual for general rules about the use of
italics. Italics are used in typeset material to help readers
quickly identify certain words and phrases, such as foreign
expressions or book titles. Typeset material and material
produced on computer should not contain underlining. Titles of
dissertations and theses, manuscripts in collections, lectures
and papers read at meetings, machine copies of typescripts
(photocopies, mimeographs, etc.) are set in Roman type and
quoted. Names of depositories, archives, and the like, and names
of manuscript collections are capped and set in Roman type
without quotation marks. Although italics are used for sic,
other Latin scholarly words and commonly used foreign words are
set in Roman (for example, ibid., in situ, et al., ennui).
Foreign words not common in English usage are italicized.
Consult Webster's Tenth. If the word is listed in the "Foreign
Words and Phrases" section of Webster's, it should be
italicized. If it's in the regular listings, make it Rom
