This is something new for eBooks. A site that you sign up for a monthly fee and get a set number of free eBooks. It's not borrowing because there isn't a time limit and you always have access even if you cancel.  There are multiple plan levels to choose from.  And while they currently have about 125,000 books to select from, they say they are adding more books all the time.  Anyone seen this?  If so, anyone sign up?
