When I wasn't a poverty-stricken scholar, I bought a lot, but I had a relatively high-paying job, so it wasn't a problem. Now, I have to only go with the ones that I really want. My wife thinks that either way I have too many. She doesn't complain nearly as much as she does about the number of books that I have, though. I keep telling her that it's only going to get worse, but that doesn't seem to make her feel any better, for some reason.
