2.1.4 Italics for Titles

Use italics for the titles and subtitles of books, journals, magazines, newspapers, and other periodicals wherever they appear—in running text, notes, and bibliographies. Capitalize these titles in title case unless a particular citation style or publication format calls for sentence case in the reference list.

When a work is cited in full in the notes or bibliography, a shorter form may be used in the main text. For example, the subtitle may be omitted when the shortened title remains clear and unambiguous.
