Uncorrected proofs of upcoming novels have been selling for large sums on eBay and Depop – despite the practice being banned by publishers

When advanced reading copies (ARCs) of Sally Rooney’s new novel Beautiful World, Where Are You were sent out in May, there was a flurry of social media posts. A lucky selection of editors, writers and influencers flaunted their copies; others bemoaned not having been granted one. Soon listings for proof copies (which are clearly marked “not for resale”) started to appear on trading sites such as eBay and Depop. One copy, listed on eBay by a seller in North Carolina, sold in June for $209.16. Even the canvas tote bag that Rooney’s publicists had been sending out with the ARC copies was fetching prices in the region of $80. And this growing market for unpublished novels is not just a product of Rooney-mania: Jonathan Franzen’s Crossroads, which will be published in October, sold earlier this month on eBay for $124.

Advance copies of popular and classic novels have long been collector’s items. A rare proof copy of JK Rowling’s Harry Potter and the Philosopher’s Stone, for example, or classics by authors such as Ernest Hemingway or John Steinbeck can sell for up to £30,000. But this high demand for ARCs of books that are yet to be published has only emerged recently, fuelled in part by the rise of book bloggers and influencers.
