It seems like every day brings some announcement about a new player or partnership in the emerging electronic book market. Members of that buzzing ecosystem are apparently eager to show their stuff at the next Consumer Electronics Show in Las Vegas. CES says it's sold out its e-book exhibition area for the next show in January 2010, and is scrambling to add more space.

Companies displaying their e-book technology at the tradeshow include Plastic Logic, which is coming out with an ultrathin reading device next year, and Shortcovers, a mobile e-reader application from Canadian bookseller Indigo Books & Music. There are also some less familiar names: Ditto Book, Ectaco Inc., Entourage Systems, Freescale, HanWang, Interead, Liquavista, Marvell, and Onyx International.

“We have received overwhelming response from companies interested in exhibiting in the eBooks TechZone for the 2010 CES," said Karen Chupka, one of the show's organizers, in a statement. "In fact, the original space allocated for the TechZone has already sold out and we are adding additional floor space to accommodate our customers."

Absent from the list is Amazon.com, which has dominated the early electronic book market with its Kindle device, as well as other big players like Sony and Barnes & Noble (though B&N is working with Plastic Logic). But it's interesting to note how many new companies are trying to elbow their way into the young but growing market. CES says e-book sales are expected to reach $317 million in 2009, with $647 million in sales projected for 2010.
