The book-publishing industry produced some 411,000 new titles and sold more than 3 billion books in the U.S. in 2007, but reading is trending downward there and in many other rich nations. Books may soon go digital, with Sonys 2004 launch of the first high-resolution e-book reader now being followed up by Amazons version, the Kindle, in late 2007. The Kindles high-speed wireless link to the Amazon site allows e-books to be downloaded in seconds. Kindle e-books are now bringing six percent of sales of the 125,000 titles Amazon currently makes available in electronic and print formats. The eventual proliferation of e-book publishing threatens to bring the kind of wholesale change that has had a powerful impact on the music industry. Textbooks represent a rapidly growing segment of electronic publishing since the platform eliminates costs for printing, shipping, storing and returns. This cost reduction which could push Springer, Elsevier and other education publishers to recapture the $2.3 billion college textbook- resale industry in the U.S. Another new, less known technology that could potentially take the industry in another direction is Print on Demand (PoD), which enables a customer to order the printing and binding of a book that may have a limited readership. According to PoD publisher Ames On-Demand, PoD has proven to be less expensive than standard printing for runs of less 1,200 copies. Given the current economic slowdown, e-book demand may see further growth. A popular title that can be downloaded in seconds for less than ten dollars might list at more than $15 for a paper copy on Amazon.com.
