I'm a second-generation bookseller. My family runs Houston's largest used & rare bookstore and I'm building an AI tool for used bookstores. We got hit by exactly these orders, including a single order for 70 obscure books that made us pause online sales entirely. So I dug in. I don't think this connects the way people want it to. Every ingredient of the viral story is true. ISBNdb really does advertise sourcing books for AI companies. Anthropic really did destructively scan millions of books though they were mostly acquired through things like library deaccessions, not bookstore inventory. And booksellers really are getting bizarre bulk orders. But "rare" here isn't what you're picturing. It's The Insider's Guide to Metro Denver (1995) and how-to-use-WordPerfect 1991 manuals. Obscure, but often not precious. When we combed through our orders, nearly every book bought from us was either unavailable on Amazon or listed there at 5, 10, 20x our price on the platform they were purchased on. And the shipments are going to FBA prep companies: which is what you do with a book you're about to resell, not one you're about to cut apart. There is more than circumstantial evidence that this is a well-funded company running algorithmic arbitrage, buying underpriced or out-of-stock books to relist on Amazon at markup. This evidence includes an official denial that they are selling to train AI but I don't want to mention them for several reasons. You can Google it. That's more mundane than the shredder story. The actual risk is worse, though, because it's quieter: books that don't sell via FBA eventually get liquidated. If we really hold the last copies of some of these (and comparing platforms, it looks like we might) we're feeding them into a portal they may not come back from. No AI company required. Everyone assumes the internet preserved everything. It didn't. Many of these books have almost no metadata anywhere, just a scattered listings across proprietary databases then nothing. That's what my project is for: building better bibliographic records for these books than exist anywhere else, so we at least have a map of what we stand to lose. So the Library of Alexandria is still burning, just more slowly, and kore from “who cares” than from some cinematic villain. (I am open to being corrected.) Full writeup: open.substack.com/pub/charli…
