Independent booksellers The Book House, Posman Books, and Fiction Addiction are suing Amazon and the "Big Six" publishers consisting of Hachette, HarperCollins, Macmillan, Penguin, Random House, and Simon & Schuster. The suit accuses the seven companies of monopolizing the e-book market by selling titles encumbered by draconian digital rights management, and says that the companies have a seeming unwillingness to enter into agreements with smaller bookstore chains or groups. The moves have limited consumers' choices, and barred independents from successfully entering the e-book market, the booksellers say.
