UK and Ireland Booksellers Hit by Bulk AI-Data Orders as Anthropic Spends Millions on Training Books

A quiet phenomenon is unfolding for secondhand booksellers across the UK and Ireland: sudden, large orders arriving from mystery buyers. The Guardian reports that traders have been contacted by buyers in the US, Canada, continental Europe and the UK, a pattern echoed in the US, Australia and Europe. What looks like a routine restock is being reinterpreted as part of a broader AI data-gathering push.

Observers say AI labs are stocking up on accessible titles to scrub them for data, with Anthropic reportedly spending millions on books to scan for data acquisition. The motive is to feed training datasets with high-diversity material, including popular titles in secondhand circulation. The scale and cross-border nature of these orders have left small booksellers puzzled and, in some cases, wary.

For the shops, the trend is a double-edged sword: more business from unusual buyers on the one hand, but a sense that the data economy behind modern AI is quietly changing the economics of used book markets. Some consignors fear that bulk orders could disrupt supply chains or devalue certain runs of titles, while others worry about copyright and provenance issues tied to data-scraping from printed works.

Beyond the counters of independent bookshops, the situation highlights a broader tension in AI: how training data is gathered, bought and used. Regulators, publishers and researchers are increasingly probing where training material comes from and who benefits, amid calls for greater transparency and fairer use. The current moment—spurred by bulk orders and high-profile spending—could push these debates from policy labs into everyday business decisions for small venues and libraries alike.

As the story unfolds, readers will want to watch how shops, buyers and policymakers respond. Clearer disclosures on data sourcing, improved provenance tracking for used books, and collaborations that protect authors, owners and readers may shape the next chapter in this evolving data economy.
