If the title of a book is an article do you italicize it?

No, you don't italicize articles in book titles.

Here's the general rule:

* Italicize the entire book title.

* Don't italicize articles (a, an, the), prepositions, or conjunctions within the title.

Examples:

* Correct: *The Great Gatsby*

* Correct: *A Farewell to Arms*

* Incorrect: *The *Great Gatsby*
