TechCrunch: HarperCollins is trying to go its own way as its contract with Amazon lapses this year. The company, which received the same renewal contract as the other big publishers, namely Simon & Schuster, Hachette and Macmillan, seems to be holding off in order to both try its hand at online book sales and flex a bit of muscle against the Bezos book empire. HarperCollins has been fairly successful in sales of its C.S. Lewis Narnia titles online and last July announced a move to sell most of its digital inventory on its own website.
