Why AI Might Be Fueling a Surge in Used Book Sales

Across the country, used bookshops are noticing an

Across the country, used bookshops are noticing an unusual pattern in their sales: large, anonymous orders that clear shelves of everything from classic literature to niche textbooks. While some might assume this is a sign of renewed interest in physical reading, industry insiders suspect a different driver—artificial intelligence.

Booksellers say these bulk purchases often involve hundreds of titles at a time, with buyers offering little explanation beyond a generic business address. The volumes, which range from out-of-print novels to academic monographs, are rarely the kind of stock a typical collector would want. Instead, many believe the books are being acquired as training data for large language models, which need vast amounts of text to improve their responses.

What happens after the sale is even more troubling to those in the trade. Several dealers report that the books are never resold or donated; instead, they are sent directly to recycling centers or pulping mills. This means that perfectly readable editions—some of which hold cultural or historical value—are being destroyed solely to extract their textual content for machine learning.

The trend has sparked a mix of curiosity

The trend has sparked a mix of curiosity and concern among independent booksellers, who are already navigating thin margins and competition from online retailers. For now, many are torn between welcoming the business and questioning its long-term impact on the availability of used books. One buyer, who declined to be named, told our reporter that he has seen the same pattern in shops across three states, but he worries that if this is indeed AI-driven, the demand could dry up as quickly as it appeared.

Publishing experts note that this practice is not illegal, and it highlights a growing tension between the tech industry’s appetite for data and the preservation of physical media. While some argue that AI companies should license books directly from publishers, others point out that the used market is a gray area where such purchases are hard to trace. For now, the mystery remains, but the smell of fresh pulp in recycling bins is a clue that the digital revolution has a physical cost.
