If you follow The Chicago Manual of Style, then publication titles are in italics, with the first letter of each word capitalized.

Short words inside the title such as a, of, the, or etc, or prepositions stay un-capitalized, regardless of length, unless they are part of an official name in the book title.


The Basset of Bakersville Cove

Ringside Seat at the Murder

Of Mice and Men

  • How do you define "short words"?

You should reproduce the capitalisation used in the book's title.

    -1: The book's title may easily be in ALL CAPITALS, and I would never use ALL CAPITALS when quoting a book title. Even worse, I expect some books have titles which are typeset like FIRE and BLOOD, and different editions may be typeset differently; cover designers feel no compunction for consistency in typesetting.
