Flooved has named several of their partners, including Business Expert Press, Bloomsbury, Momentum Press, Manson, and ITN News Source. They're also hinting about a deal in the works with one of the major publishers.
You know, this could be a good deal for students, but that's going to depend on the title selection. At the very least this will be better than most of the digital textbook rental services like Coursesmart, which charged around 70% of the retail price in exchange for 3 or 6 months access. I know that renting textbooks is not the same as a subscription, but given that access is cut off if you stop paying for either I would say that they are more similar than different.
