A new chapter is being written in the world of book sales. For every 100 print books Amazon.com has sold since April 1, it has sold 105 e-books. That includes sales of hardcover and paperback books for which there is no e-book edition. The electronic retailer also announced its fastest year-over-year growth rate for its U.S. book business, in both units and dollars, in more than a decade. That included books in all formats, print and digital.
E-books continue to take market share away from large brick-and-mortar retailers. Borders filed for bankruptcy earlier this year and closed 30 percent of its stores.
