Barnes & Noble, the ginormous US book store chain has just announced its very own eBookStore. And as you might expect from a heavy literary retail hitter like B&N, they are doing things big. It already features some 700,000 eBooks. According to them, that’s the largest eBook store ever.

And you can bet that they expect that selection to grow quickly. The company also announced a partnership with Plastic Logic, which is an eBook manufacturer and says that they will be catering to every platform. Everything from Apple, BlackBerry phones and PCs. Best sellers and new releases will be $9.99, competing with Amazon. This will be interesting to watch.
