With the e-book industry expected to explode into a multibillion-dollar business in the next three years, Barnes & Noble wants to open a new chapter in sales by making sure its products are available on Apple's iPad. The retail giant on Thursday confirmed reports that it is preparing an iPad application in time for the anticipated April 3 release.

Digital Library Preserved

"Designed specifically for the iPad, our new B&N eReader will give our customers access to more than one million e-books, magazines and newspapers in the Barnes & Noble e-bookstore, as well as the existing content in their Barnes & Noble [online] digital library," Barnes&Noble.com administrator Paul Hochman wrote on a company blog.

The app will allow customers who have already downloaded content to Barnes & Noble's nook e-reader to access the same material on the iPad, Hochman said.

While the iPad is a direct attack on the nook, which debuted over the holiday season, as well as Amazon.com's Kindle e-reader, the B&N eReader shows that Barnes & Noble is doing everything it can to adjust to the digital age as paper books sit longer on the shelves.

"Barnes & Noble is first and foremost a content retailer, not a gadget maker," said consumer-devices researcher Avi Greengart of Current Analysis. "It is far more important for [the company] to ensure that when -- or if, as the case may be -- reading moves from the physical realm to digital that Barnes & Noble maintains its place in the distribution chain."

Greengart also predicted an iPad app for the Kindle, which is already available for Apple's iPhone and iPod touch. The app, he noted, would have to be optimized for the iPad's higher screen resolution.
