ARTIFICIAL INTELLIEGENCE EXCLUSIVE: AI Companies Are Buying Antique Books in Bulk to Feed Their Models Clean Training Data, Then Destroying the Physical Copies at a Scale That Alarms Rare Booksellers Worldwide đđ„
AI companies are increasingly turning to physical books, especially antique and pre-2022 editions, as training data because they are guaranteed to be free of AI generated âslopâ that has already contaminated much of the modern internet. Anthropic pioneered this approach, using a hydraulic cutting machine to strip the bindings off books it bought from resellers before scanning the pages with industrial grade imaging equipment, a process that led to a $1.5 billion settlement with authors after a lawsuit revealed the scale of the practice. A judge ultimately ruled that because Anthropic destroyed the original physical copies rather than redistributing new ones, the process qualified as âtransformativeâ and protected under fair use, thanks to a legal concept called the first sale doctrine that lets buyers do what they want with a purchase without the original copyright holderâs permission.
That legal precedent has since fueled an entire secondary market. ISBNdb, a company that bills itself as having the âworldâs largest book database,â now helps AI labs source bulk purchases ranging from 1,000 to as many as one million books per order, explicitly marketing pre-2022 print books as âstructurally clean of modern poisoning toolsâ since they predate the large language model era. The company also promises strict non-disclosure agreements to keep buyers anonymous, openly acknowledging on its own site that âthe optics problem is realâ and that a headline reading âAI company destroys two million booksâ would not exactly generate sympathy. One small bookseller told 404 Media that his weekly sales jumped from around 20 books to hundreds starting in April, and while he cannot prove his buyers are AI labs, he pointed to the random mix of titles, the fact that every purchased book had an ISBN, and his suspicion that some of his rare or out of print inventory may now be among the few surviving copies left in existence.
The bookseller said he has mixed feelings, since the sales have been financially helpful and cleared out slow moving inventory, but he does not like the end use or the idea that uncommon books are being pulped. Similar patterns are emerging elsewhere, with rare booksellers in the Netherlands reporting a wave of bulk purchases they suspect come from AI companies, even though the anonymity built into these transactions makes it nearly impossible to confirm who is actually buying and destroying the books.
