NYT via Daring Fireball:

Amazon, under fire in much of the literary community for energetically discouraging customers from buying books from the publisher Hachette, has abruptly escalated the battle.
The retailer began refusing orders late Thursday for coming Hachette books, including J.K. Rowling’s new novel. The paperback edition of Brad Stone’s “The Everything Store: Jeff Bezos and the Age of Amazon” — a book Amazon disliked so much it denounced it — is suddenly listed as “unavailable.”
In some cases, even the pages promoting the books have disappeared.

I'm actually reading The Everything Store: Jeff Bezos and the Age of Amazon right now. The writer makes it very clear that he had Bezos' blessing to do the book, and permission to interview hundreds of his coworkers, family, and friends. Seems like he didn't like what he read once it was complete. Maybe that's because the book depicts him as the ruthless guy that he is. The kind of guy who would pick on a publisher and make their books "unavailable" in his online store.
