AI firms quietly buying rare books, destroying them to train models

AI firms quietly buying rare books, destroying them to train models

3 Key Points

  1. What happened

    A lawsuit in summer 2025 revealed that Anthropic destroyed millions of print books to train its AI models. Since then, rare booksellers have reported suspicious bulk orders—including an Irish bookstore that flagged an order for 5,000 obscure titles with no price haggling, a now-obvious red flag for AI involvement.

  2. Why it matters

    Rare books cannot be replaced once destroyed. AI firms can legally purchase and destroy books they own, but the practice threatens the survival of hard-to-find titles and undermines authors' intellectual property rights. Some booksellers now refuse orders suspected of destined for AI training, fearing they are "signing their own death warrant" by enabling the loss of their inventory.

  3. What to watch

    Non-destructive alternatives exist—Google patented a non-destructive book-scanning method in 2009, and the Internet Archive uses labor-intensive hand-scanning to preserve rare books physically while digitizing them. OpenAI and Microsoft are partnering with Harvard librarians to train AI on about 1 million public-domain books from the 15th century onward. Whether major AI firms adopt preservation-focused methods or continue cutting corners will determine whether rare collections survive.

Context & Analysis

The tension between AI training efficiency and book preservation reflects a deeper clash between speed-to-market and stewardship. A lawsuit in summer 2025 exposed Anthropic's destruction of millions of print books, and the backlash has forced the company to adopt a codename—"Project Panama"—for its destructive scanning efforts in an attempt to hide the practice from public scrutiny. The discovery has mobilized rare booksellers, who now recognize suspicious bulk orders as markers of AI involvement: large batches of unrelated titles purchased without price negotiation stand out sharply from typical library or university acquisitions. The industry's concern is not merely sentimental—it reflects a real threat to the survival of irreplaceable collections and an erosion of authors' intellectual property rights. Yet the economics of AI training create powerful incentives to cut corners. Non-destructive alternatives do exist: Google's 2009 patent, though imperfect, offers a blueprint, and the Internet Archive's labor-intensive hand-scanning—developed over decades and perfected by scanners like Eliza Zhang, who has processed more than 3 million pages and 18,000 items—demonstrates that preservation and digitization can coexist. The question now is whether public backlash and the commitment of firms like OpenAI and Microsoft to preserve public-domain collections will be enough to shift the broader industry toward preservation-focused methods, or whether cost pressures will continue to drive destruction.

FAQ
How are AI companies destroying books to train their models?
The cheapest and fastest method is to cut off book spines and feed pages into machines for scanning, then discard them. This avoids the time and labor investment required by non-destructive methods like hand-scanning used by the Internet Archive.
What non-destructive scanning methods exist?
Google patented a non-destructive book-scanning technology in 2009, though studies show page curves can distort text and pages may be missed. The Internet Archive uses careful hand-scanning—workers use foot pedals to raise scanner glass, adjust cameras, and ensure readability page by page—a method the Internet Archive says works best for fragile and rare books, with proprietary software catching errors and prompting rescans.
Are any AI firms committing to preserve rare books?
OpenAI and Microsoft are working with Harvard librarians to train AI models on about 1 million public-domain books dating back to the 15th century. Elon Musk said he asked the xAI team to scan rare books the hard way instead of destroying them, though critics note he did not commit xAI to avoiding book destruction entirely.
