Flat World Knowledge

We had the bestseller "The World is flat: A brief History of the Twenty-first century" from Nobel price winner Thomas L. Friedman. Now we have Flat World Knowledge: webpage where extremely high-quality open educational resources can be produced and disseminated in a way that is sustainable over a long term. It combines free access and publishing on demand, so you might have the best of both worlds.  

First books are already online for free, and there is a catalog and a publishing list.
