Since Logos has all these books available that most people will never be able to buy but would like to use every now and then and since it seems to me that Logos already has a way of tracking the user licenses why not offer a book borrowing/leasing service? I know there may be issues with the publishers that need to be ironed out but Logos itself is a publisher and they should be able to do this on their own titles. Also a user to user book lending/borrowing feature would be a great plus because it would allow users to exchange books. This service is already available for Kindle.
