Which capitalization is correct for a title used in a header?

• A. The Great Gatsby is a novel.
• B. the Great Gatsby is a novel.
• C. The great Gatsby is a novel.
• D. The Great gatsby is a novel.

Answer: (A)

In headers, the title portion is treated as its own proper name and is written in its usual title-case form, while the rest of the header follows sentence-style capitalization. So when you include a book title inside a header, you keep The Great Gatsby capitalized exactly as the title appears (The, Great, Gatsby), and you write the remaining words in lowercase (is, a, novel). That yields The Great Gatsby is a novel, which keeps the title correctly emphasized and the rest of the header in standard sentence-case. The other options would mis-capitalize or alter the words outside the title portion, which wouldn’t match typical header conventions.
