WASHINGTON (Reuters) – The plot of the Amazon-Hachette battle over ebook prices just acquired a strange literary twist. Amazon is asking readers to help in its running dispute with Hachette Book Group by emailing Hachette’s CEO. But it may have missed the mark when it picked on English writer George Orwell to make its point. In a message from the Amazon Books Team on a website one recent Friday evening, Amazon.com Inc reiterated its arguments for cheaper ebooks, and suggested people email Hachette CEO Michael Pietsch. The company published Pietsch’s email address and listed key points people might want to make.
