Books being destroyed to train AI chatbot sparks global secondhand book boom.

Something mysterious has been happening in the world of secondhand books.

The Rise of Bulk Orders

Over the last few months, independent booksellers have been observing a strange pattern of purchases that have seen scores of their novels being shipped to far-off warehouses.

In a typical week, Stuart Manley, from Barter Books in Northumberland, would sell two or three thousand books. But one recent single bulk order from a Canadian company equalled what he would expect to move in seven days.

He says he has 'never seen the like of this after 30 years in the second-hand book trade.'

Mr Manley is not alone. Booksellers from around the world have been reporting similarly unusual mega orders.

The suspicion is that these books are not being bought for avid overseas readers but instead something else with a voracious appetite for new information: AI.

The idea that the secondhand sales boom is being driven by the explosive growth of AI can be traced back to a court ruling in the US.

A lawsuit brought against AI firm Anthropic by three authors led to a court decision that Anthropic's use of the authors' books was 'exceedingly transformative' and therefore allowed under US law.

When court documents were unsealed last month, it emerged that books were being destroyed in the process of training Anthropic's AI chatbot, Claude.

'Claude is trained on a mix of publicly available web data, commercially acquired datasets, and data we generate ourselves,' said a spokesperson for Anthropic.

They insisted sourcing books for training was a widely used approach across the AI industry.
