Every time 10,000 Goodreads members add A Visit From the Goon Squad to their shelves, the organization promises to donate 1,000 books. So far, 25,000 members have added the book. If another 5,000 members follow, then Goodreads will provide 3,000 books.

Here’s more from the site’s blog post: “Our initial goal is to donate 5,000 books—which means we need 50,000 people to add A Visit From The Goon Squad by August 2, when the Book Club concludes with a live video chat with author Jennifer Egan. If more than 50,000 people add the book before the end date, we will honor our pledge and donate up to 10,000 books!”
