Q. How do I cite a book that begins with an A in the title?

If there is no author, you will capitalize each word in the titles of articles, books, etc, but you will not capitalize articles (a, the, an), prepositions, or conjunctions unless it is the first word of the title or subtitle: 

Gone with the Wind 

The Art of War 

There Is Nothing Left to Lose 

These will be alphabetized in your reference list by the first important word of the title.
