Most colleges are making the first efforts to initiate the move. There are several reasons, one of which is lower costs, another is flexibility. A class textbook must be selected months in advance. A few years ago, I took a class where the instructor moved just before. I had purchased the text he had chosen, but the new instructor changed the textbook. With digital textbooks, it would be simple to download in the first day of class, with updates and instructor notes. With a local hub setup, homework can be turned in instantly. Also do not forget that books take a large amount of room and space is often at a premium on campuses.
