I am well on my way to being an amateur book collector of things no one wants. I have started collecting antique books on mathematics. I am not at all sure if I'm buying books that well one day be worth something or not, but really, I don't care. I enjoy it and they are usually pretty cheap. I was able to pick up 6 new books today for nothing at an estate sale in Venice. I figure now is a good time to list what I've got and then I'll make updates as I find new stuff.
