How do you store your books? On bookcases? In piles? In piles on bookcases? Are they sorted? Do you know where everything is? What’s the most creative storage you’ve seen or used for your books?

I have my books everywhere in my house. Some are on shelves, some are on piles on shelves, some are just in piles, resting against a bookshelf, some are on my desk, some are in piles in the bedroom. We have a lot of books and not enough space for them!
