Thanks for that link! That's very interesting. I am editing two books for two authors at the present, both of whom already published, in paper, and with Amazon I believe. But this looks like a very interesting publishing model. Especially for more technical books. There are a few in progress that I know about. (Is emacs something different than the apple computer?)
