I have a good collection of old science books. One of my favorites is called "The Perfect Woman", publish in 1896, and it is a manual for women. It's precisely as horrifying and unintentionally hilarious as you would expect. But mostly I collect early editions of my favorite stories, or occasionally limited editions like from Subterranean Press. And no, I have not seen The Booksellers. I got into this because as a kid I'd buy a lot of books from our neighborhood used book dealer, mostly cheap science fiction paperbacks. I've tried ebooks a couple of times, and I just don't like them. I wish I did because it's highly convenient. But I just really prefer paper. For one thing you can give away your book when you're finished with it, or loan it to a friend, neither of which you can do with an ebook.
