Secondhand book sales have surged in recent months, with many independent booksellers reporting unusually large orders from unknown buyers. In a typical week, Stuart Manley of Barter Books in Northumberland would sell around 2-3 thousand books, but one order from a Canadian company equaled this amount in just one day. Booksellers are speculating that the surge in sales may be due to artificial intelligence (AI) companies buying up large quantities of books for training purposes, as a US court ruling in 2025 allowed AI software training to use copyrighted materials without violating copyright law. This has raised concerns about the impact on the book industry and the potential destruction of physical books. One company, Anthropic, has been specifically linked to this practice, with reports suggesting they have bought millions of physical books to train their AI chatbot Claude.
