I have just spent the better part of two days rearranging furniture and shifting some 750 books in order to have them all situated in my bedroom. This is because before the bookshelves were mostly in the room the kids use as a playroom, and the baby was starting to pull books off shelves, or (worse, I think) pick at and tear the edges of dust jackets. This is one of her favorite activities; she has more fun pulling all her books off her shelf than actually reading them (lately she tries to turn the pages herself and sometimes gets frustrated trying to open the book at its spine! lots of screaming ensues- it's so funny).
I'm pleased overall. Something about moving and re-organizing and re-familiarizing myself with all my books feels very satisfying. I keep turning over in my hands titles I'd dearly love to re-read! And now my bedroom feels like a little library, which is very cozy.
