Penguin Books says it has agreed to settle with the U.S. Justice Department over alleged e-book price-fixing, joining other major publishers who\'ve deals. The agreement isolates Apple and Macmillan as the only publishers who have not settled, leaving them facing a trial slated for June, TG Daily reported Wednesday. Previously, Hachette, HarperCollins and Simon & Schuster negotiated agreements in the face of accusations they circumvented retail price competition, causing consumers to pay millions of dollars more for e-books. \"If approved by the court, the proposed settlement with Penguin will be an important step toward undoing the harm caused by the publishers\' anti-competitive conduct and restoring retail price competition so consumers can pay lower prices for Penguin\'s e-books,\" said Jamillia Ferris, chief of staff and counsel at the Justice Department\'s Antitrust Division. \"Since the department\'s settlement with Hachette, HarperCollins and Simon & Schuster, consumers are already paying lower prices for the e-book versions of many of those publishers\' new releases and bestsellers,\" she said.
