Maria Bustillos writes: “On June 1, Penguin Random House, together with fellow megapublishers Hachette, HarperCollins, and Wiley, filed a lawsuit against the Internet Archive alleging ‘mass copyright infringement.’ The Internet Archive closed the National Emergency Library on June 16, citing the lawsuit and calling for the publishers to stand down. But the plaintiffs are continuing to press their claims, and are now seeking to close the whole Open Library permanently. But what’s really at stake in this lawsuit is the idea of ownership itself—what it means not only for a library but for anyone to own a book.”
