While Amazon is best known for selling new products, an estimated 23 percent of its sales are from used goods, many of them secondhand books. Used bookstores have been around for centuries, but the Internet has allowed such markets to become larger and more efficient. And that has upset a number of publishers and authors.
In 2002, the Authors Guild and the Association of American Publishers sent an open letter to Jeff Bezos, the chief executive of Amazon.com, which has a market for used books in addition to selling new copies. "If your aggressive promotion of used book sales becomes popular among Amazon's customers," the letter said, "this service will cut significantly into sales of new titles, directly harming authors and publishers."
