I have gone window-shopping for bookshelves, and there's a pretty nice-looking one I've seen at Ikea. I just haven't bought it what with that whole problem I have about spending money on the obviously useful things.

Weirdly enough, my non-paperback books tend to fit into a pretty nice continuum of sizes. I can arrange them in a pretty smooth fashion just on size alone. It's choppier bundling them by subject, but if I just want appearance they should go very nicely.
