From Chapter 7, 'Italics'

7.3   Titles of Books and Other Writings

Italics are used for the titles of all works individually published under their own titles: books, journals, plays, longer poems, pamphlets, and any other entire published works. However, titles such as ‘the Bible’, ‘the Koran’, and ‘the Talmud’ are printed in roman, as are titles of books of the Bible (see 11.2.8). Titles of series are not italicized, e.g. ‘Theory and History of Literature’. The titles of chapters in books or of articles in books or journals should be in roman type enclosed within single quotation marks (see 11.2.3 and 11.2.4). The titles of poems, short stories, or essays which form part of a larger volume or other whole, or the first lines of poems used as titles, should also be given in roman type in single quotation marks:

Théophile Gautier’s ‘L’Art’; Keats’s ‘Ode on a Grecian Urn’; Shelley’s ‘Music, When Soft Voices Die’; Joyce’s ‘The Dead’; Bacon’s ‘Of Superstition’

The titles of collections of manuscripts should be given in roman type without quotation marks (see 11.2.9). The titles of unpublished theses should be given in roman type in single quotation marks (see 11.2.6).

As recommended in 5.5, titles of other works which appear within an italicized title should be printed in italics and enclosed within single quotation marks:

An Approach to ‘Hamlet’

In the citation of legal cases the names of the contending parties are given in italics, but the intervening ‘v.’ (for ‘versus’) is in roman:

Bardell v. Pickwick
