AI firms reportedly buying bulk secondhand books for destructive scanning after US copyright ruling

Independent booksellers worldwide have observed a surge in bulk purchases of secondhand books, often shipped to warehouses with unclear final destinations. The scale of these orders, such as a single purchase equaling a week’s typical sales, suggests a systematic effort rather than individual demand. While sellers are unsure of the exact use, speculation centers on AI firms acquiring these books for training datasets, particularly after a 2025 US court ruling permitted the practice under copyright law.

The court case involving Anthropic revealed that books purchased for AI training may be subjected to destructive scanning, a process where spines are removed to digitize pages at scale before recycling the remains. Internal documents referred to this as 'Project Panama,' with the stated goal of 'destructively scanning all the books in the world.' The diversity of titles, from obscure Latin texts to cowboy novels, aligns with AI training needs, as rare or unusual material can improve model performance. However, the lack of transparency from buyers leaves sellers guessing about the fate of their inventory.

Ethical and legal concerns arise from this practice, particularly regarding the destruction of books that may be rare or culturally significant. While some sellers acknowledge that not all titles merit preservation, the loss of unique editions, such as the only surviving copy of an 18th-century work, raises alarms. The discrepancy between US and UK copyright laws adds complexity: the US ruling allows such use without permission, while UK law requires explicit consent from copyright holders. This creates compliance challenges for AI firms operating across jurisdictions.

For engineers, this trend highlights the operational and reputational risks of sourcing training data. Destructive scanning may offer cost efficiencies, but the ethical backlash and potential legal exposure could outweigh the benefits. The lack of industry-wide standards for data acquisition further complicates matters, as firms like Anthropic argue the practice is widespread. Booksellers, meanwhile, face a dilemma: the financial upside of bulk sales versus the discomfort of contributing to the destruction of books, even those with limited cultural value.
