This O’Reilly’s Books & Videos page is a something of a primer for what is going on at the edge of ebooking. In the copy there designed to sell the company’s offerings, a lot is explained about the options in this exploding new venue.

The page caught my eye in O’Reilly’s newsletter headline that included “1500 DRM-Free Ebooks. . . . four DRM-free file formats — PDF, .epub, Kindle-compatible .mobi, and Android .apk — that you can use on the devices of your choice.”

It is interesting to see DRM perhaps dancing away. Can truly open be far behind?
