In recent months Amazon has been hiring highly respected editors, and the company is putting out 122 titles this fall. Amazon is already the world's largest retailer of books. As a publisher, it will be selling its own products alongside products by the "big six" publishers — who are not only partners, but now rivals as well. The Big Six include Hachette Book Group, Harper Collins, Macmillan, Penguin Group, Random House and Simon & Schuster.
