This comes on the heels of the news about Scribd launching their own bookstore. In that case, the interest comes for the fact that the books have no DRM, and that what had been a site just to disseminate free books and documents has now gone into selling them. You could see it as going head-to-head with Internet giant Amazon, as Scribd will work with traditional publishers and gives them more favorable terms than Amazon does.
So, exciting times on the digital front!
