The Electronic Frontier Foundation (EFF) is teaming up with law firm Durie Tangri to defend the Internet Archive against a lawsuit filed by publishers Hachette, HarperCollins, John Wiley, and Penguin Random House. The lawsuit targets the Internet Archive's Open Library and National Emergency Library, which provided unlimited borrowing of over a million books during the COVID-19 pandemic. The publishers claim that the libraries are pirate services that threaten their businesses. The EFF and Durie Tangri argue that the Controlled Digital Lending program is no different from what other libraries offer and is a vital public service.
