This past week, Amazon deleted copies of George Orwell's 1984 and Animal Farm from users' Kindles. The books in question were legitimately purchased, or were they? Reports surfaced that MobileReference, the publisher who transfers public domain books to electronic format to sell for the Kindle, didn't have the authority to sell the books. Because the books are not yet in the public domain, the license to the book was deemed invalid and the books were deleted. The books have been removed from both the Amazon store and the MobileReference website. Amazon has said that the purchasing system was designed to take these actions automatically and will be changed for the future.
