Just so, can you use a book title that already been used?
Much like names, slogans and ideas, titles are not protected by U.S. copyright laws (which is why so many books have the same titles). As for whether or not it's a good idea to go with a title that's already been used—and in the same genre, no less—that's a question best suited for your editor.
Additionally, are book titles protected by copyright? A: Copyrights cover works fixed in a tangible format, but because titles are typically short, they don't fall under copyright protection. So no, you can't copyright a title to a book, song or movie. But you can trademark a title, which may give you the protection you seek.
Also asked, how do I find out if a book title already exists?
If you want to see if a title has been trademarked, you can use TESS, the online search at the U.S. Patent and Trademark Office.
How long is too long for a book title?
According to an analysis of book titles by Michael Tauberg, the average book title length for fiction books has increased from 2 to 3 words. Which makes books with five or more words in the title stand out against the competition, for good or for ill. One last caveat.
