It's my (non-lawyer) impression that titles of individual works (books, short stories, songs, albums, etc.) have little or no trademark protection by themselves... a name has to be used in an ongoing way, as in a series of works or in related merchandising before it has trademark significance. After all, names of stories, songs, etc. get re-used all the time; there are quite a number of different songs (not to mention a movie, etc.) named "My Girl", for instance. "What A Girl Wants" was a Christina Aguilera song and a completely unrelated Amanda Bynes movie.
