Updating the blog was on my priority list for many months (!!) but due to other professional commitments I couldn't do it..
Recently I came across a site http://www.flatworldknowledge.com/ where users can access free and open college textbooks. Anyone can read the book online but for customization / adoption one needs to register. There is separate provision for faculty as well as students.
This is a good start for online free textbooks.
From Indian point of view there should be more such efforts where Indian textbooks will be available free and online. This will change the educational scenario as the present one is unaffordable due to high fees. At least students can get the access to books and study material free.
