Barnes & Noble has just announced that they will be opening their very own e-bookstore, where for only $9.99 a book users will be able to obtain all the latest best sellers. Barnes & Noble plans to offer more than 700,000 titles, which include more than 500,000 public domain books from Google. These numbers are expected to increase to more than one million within the next year. William J. Lynch, president of Barnes & Noble’s BN.com announced this:

“Book formats supported by the new Barnes & Noble e-bookstore include those that can be viewed on Apple Inc.’s iPhone and iPod Touch, BlackBerry smartphones and most Windows and Mac computers.  Titles bought through Barnes & Noble’s e-bookstore won’t be compatible with Sony’s Reader or Amazon.com’s Kindle e-book reader, the two dominant e-readers in the U.S. market.”

The e-book market is new and growing fast. How big it actually is still unclear but it’s estimated at $75 million to $100 million in sales. Expect the Barnes & Noble Ebookstore soon. Do we hear Amazon trembling?
