Barnes & Noble Rattled by the Rise of e-Books

"In the first five months of 2009, e-books made up 2.9 percent of trade book sales. In the same period in 2010, sales of e-books, which generally cost less than hardcover books, grew to 8.5 percent, according to the Association of American Publishers, spurred by sales of the Amazon Kindle and the new Apple iPad. For Barnes & Noble, long the largest and most powerful bookstore chain in the country, the new competition has led to declining profits and store traffic."
