STAMFORD, CT -- 06/15/09 -- Simba Information, which recently produced the groundbreaking "Trade E-Book Publishing 2009" report, has added "Trends in Trade Book Retailing" to its research offerings. The report provides a detailed assessment and size estimate of the book industry through the lens of the four channels: Bookstores, the Internet, book clubs, and "other" and contains at least one warning for the industry. "The effect of channel-stuffing blockbuster books is being felt on bookstores, large and small," said Michael Norris, senior analyst at Simba Information, who added that the total number of bookstores in the U.S. has shrunk significantly over the years while the number of big-box department stores has jumped. "They have a place in the retailing ecosystem, but when you combine the convenience of the 'non-bookstores' with their ability to sell popular books at a loss you get a volatile situation for the entire industry."
