A lot of my decorating books show cool arrangements for bookshelves... that's something that's always sort of bugged me about where I live, there are no books out. No coffee table books, no books stacked up on the mantel, just... no books. I like people to walk into where I live and see my books. They look cool, sure, but they say a lot about who I am. I have basic literature and poetry. Lots of engineering books. Some for programming and computers. Required feminist material. Popular non-fiction science paperbacks, and a few sci-fi/fantasy books that friends said I "had" to have. Every time I've moved I've looked at them and cringed, because they're heavy and bulky and a pain to deal with, but this time it hasn't bugged me so much because they've been shoved in the basement for the last 18 months and I get to live in a place where they'll be out and available again. Sure I love the library, and I get rid of books fairly often, I don't have WALLS of them. But it's nice to have a few favorites.
(I just realized how strongly I wanted to defend book ownership in that last paragraph, explain why it's worth it to own my favorite books, then I remembered this is LIVEJOURNAL, if there's any group of people who automatically understand it'd be you all, I'd hope!)
