Actually im not. I deal with old books every day. What youre talking about is the modern publishing space where books get pulped by the millions because they are textbooks that weren't picked up by enough schools. Or theyre no longer the latest edition. Even regular consumer books get pulled for not having enough sales.

The used market is still full of these books even after being abandoned by the publishers. But even that market is still driven by demand. Used bookstores only buy books if they think they'll sell. But the thing is they still bulk sell those books that dont have market value because people will buy huge pallets of books for pennies on the dollar.

Yes libraries also recycle books that have been on the shelves too long. And it's hard to sell old library books because of the extreme use they are put through. They do library sales for old books pretty regularly. Most of the time they are pulping books that are worn out. Which still suggests a demand, worn books are read books.

What they're doing is taking old texts from warehouses that are known to be abandoned copyright, since stealing modern writing has proven to be unpopular. And so unknown old works are basically free game. And at best they are saving it digitally, which is good, but then selling access since after destroying the physical copy so as to have a monopoly on the data. And moatly theyre selling it to ai companies to use as training data. So basically theyre squatting old rare text that they have no actual right to.
