This is pretty standard advice, but find forums, blogs, clubs for book-lovers. They can help promote for you (if they like your idea). Pitch to them like you would any VC or angel investor but cater to their passion for books. Where do people like to read books? Coffee shops? Parks? Maybe you can add marketing material to these areas? In general, what advantages do you offer over, say, Amazon's marketplace?
