For months, authors have complained about being caught in the middle of a very public spat between Amazon, the worlds largest bookseller, and publisher Hachette. Amazon has aggressively worked to secure better contract terms with the publisher, and in the process has turned to controversial negotiation tactics like halting pre-orders for upcoming Hachette books, cutting down on physical inventory, and hitting customers with abnormally long shipping delays. Now, Amazon says its willing to give authors something more: a bigger cut of ebook sales. Both The Wall Street Journal and The New York Times are reporting that Amazon has circulated the offer via a letter sent to authors and their agents.
