So, I bought Frank Herbert's Dune today. Not for the first time, mind you — I first got it in paperback back in 1984, a few months before the David Lynch movie came out, and then in high school I bought another mass market to replace that edition after it fell apart (also I'd never finished the novel), and then in grad school, about eight years later, I bought a third copy with the 30th anniversary cover (which I actually did read, finally, for real, from beginning to end). And today, while killing time at B&N, I ended up buying a fourth copy in the weird "tallback" mass-market format. I'm not even a fan of that format, but it was a nice, solid-looking brick of a book (literally, it is the size, shape, and thickness of a brick), the print was crisp and clean, and the binding had a nice "give" to it — it didn't feel like I'd destroy it after a single reading like most mass markets. My timing was arguably off, since next year is the 50th anniversary of the novel's publication, and so there will probably be an even nicer edition with better art design and some other crap. But I saw the documentary about Jodorowsky's failed attempt to adapt the novel back in the '70s a couple of weeks ago, and my spice jones kicked in.
I tend to do this with a lot of my favorite books, or books I feel I should read but never finished or got around to starting. I've had at least six editions of LotR, two or three of them in the omnibus format. I also have multiple copies of The Last Unicorn, Neuromancer, and Little, Big. I've bought H.P. Lovecraft and Ray Bradbury's works in more formats than I care to say, as well as Philip K. Dick and Kurt Vonnegut. I'm starting to do it with Neil Gaiman. In some cases, it's just an excuse to read the books again, or if the old editions were ugly or beat up, as was the case with the cool quality paperback reissues of Alfred Bester and Samuel Delany. I didn't use to do this when I was younger — a book was a book back then — but now it's kind of an obsession, and I'll probably keep doing it as long as there are real books.
Am I just nuts here? Do any of you guys do the same? And if so, what books or authors?
