You're minding your own business amidst the rows of books, when you happen to notice a hottie standing next to you. What is he doing? Is he scanning the bookshelf? Ask him which book he's looking for. Or if he's reading a page from a book as he stands, ask him if it's any good.

Remember, you don't have to open a conversation with totally a cliché pick-up line. A simple, interested question and a smile will work wonders!
