Independent booksellers have reported unusual bulk orders from companies in recent months, with some seeing sales of up to 2,000 books per week. The exact destination of these books is unknown, but many suspect they are being purchased by AI firms for use in training software, such as Anthropic's chatbot Claude. According to court documents, Anthropic uses "destructively scanned" books for training, which involves removing the spine and recycling the remains after digitizing the pages. This has raised concerns among booksellers about the fate of rare and antiquarian titles being sold in these bulk orders.

Something mysterious has been happening in the world of secondhand books.
asserted
Something → publish → books
Over the last few months independent booksellers have been observing a strange pattern of purchases which have seen scores of their novels being shipped to far-off warehouses.
asserted
scores → observe → warehouses
In a typical week, Stuart Manley, from Barter Books, in Northumberland, would sell two or three thousand books.
asserted
Manley → sell → books
But one recent single bulk order from a Canadian company equalled what he would expect to move in seven days.
asserted
he → equal → days
He says he has "never seen the like of this after 30 years in the second-hand book trade".
asserted
he → say → trade
Booksellers from around the world have been reporting similarly unusual mega orders.
asserted
Booksellers → report → orders
But the suspicion is that they are not being bought for avid overseas readers but instead something else with a voracious appetite for new information: AI.
asserted
they → buy → information
The court battle over books
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.
asserted
boom → drive → US
In 2025, a judge ruled using books purchased in this way to train AI software was not a violation of US copyright law.
asserted
using → rule → law
The decision was the result of a lawsuit brought against AI firm Anthropic by three authors.
asserted
decision → bring → authors
In his ruling, Judge William Alsup said Anthropic's use of the authors' books was "exceedingly transformative" and therefore allowed under US law.
asserted
use → say → law
When court documents were unsealed last month it also emerged books were being destroyed in the process of training Anthropic's AI chatbot, Claude.
asserted
books → unseal → chatbot
"Claude is trained on a mix of publicly available web data, commercially acquired datasets, and data we generate ourselves," a spokesperson said.
asserted
spokesperson → train → data
They insisted sourcing books for training was a widely used approach across the AI industry.
asserted
sourcing → insist → industry
"None of our data acquisition programs buy and destroy rare or antiquarian books," they added.
asserted
they → buy → books
Nonetheless, the idea that books are being pulped is causing unease.
asserted
books → pulp → unease
David Tobin, runs Walden Books in north London, has also had unusual sales.
asserted
Tobin → run → sales
"In some ways it's very nice to sell some of these titles which haven't been sold for many years, but it would be sad if they are ultimately destroyed," he says.
asserted
he → sell → years
The court documents relating to the Anthropic case revealed the project of ingesting old books was referred to in internal company communications as "Project Panama."
asserted
project → relate → Panama
The documents indicated the company's aim was to "destructively scan all the books in the world".
asserted
aim → indicate → world
Destructive scanning is the process of shipping books to locations where they can be digitised at an industrial scale.
asserted
they → ship → scale
It includes removing a book's spine so all the pages can be scanned rapidly - and the remains recycled.
asserted
remains → include → spine
"A lot of mystery surrounds Project Panama," Manley, from Barter Books, says.
asserted
Manley → surround → Books
He does not know that his books are being bought for it or similar projects by other AI firms.
asserted
books → know → firms
But he says it's also difficult to account for the sales, which appear random with "no rhyme or reason."
asserted
which → say → rhyme
They have varied from obscure Latin texts to cowboy novels.
asserted
They → vary → novels
Experts say the diverse subject matter also points to AI, as unusual and rare texts could provide fresh material to improve the training of large language models, the tech which underpins generative AI tools like chatbots.
uncertain
which → say → chatbots
Professor Emily Hudson, intellectual property specialist at Oxford University, says copyright laws in the UK are different to those in the US.
asserted
laws → say → US
"The starting point in the UK is that all these acts of copying - creating the training library and doing the training – require the permission of the copyright owner," she says.
asserted
she → create → owner
Ethical concerns
For the booksellers, it poses a dilemma.
asserted
it → pose → dilemma
They are uncomfortable with the idea of books being destroyed - even if they admit not every title needs to be saved.
asserted
title → destroy → idea
"A recent academic text published in only 100 copies, 75 of which are already in libraries, may be very rare on the market - but it is perhaps not such a great loss if one copy is destroyed," says Derek Walker, owner of Edinburgh bookshop McNaughtan's.
uncertain
Walker → publish → McNaughtan
"But we have, and have sold, books which are for example the only known surviving example of an edition from the 18th century.
asserted
which → have → century
"It would be a much more significant problem if one like that were to be bought for destruction, having survived this long.
asserted
one → buy → destruction
And Manley says recycling books is a good solution for many titles which the public no longer want on their shelves - especially when it comes with a bump in trade.
asserted
it → say → trade
"Some may have ethical concerns about where the books end up and if they're destroyed," he says.
"
uncertain
he → have → concerns
But the world no longer needs five million copies of The Da Vinci Code.
asserted
world → need → Code
"I've had books advertised for 20 years on the web which haven't sold until now".
asserted
which → have → web
