When you buy books from Amazon, is each one an independent license, or is there one master license for your account?
I'd have to look careful at the Amazon licences again -- I have the impression they are separate licences for each title. That is impression is partially based on the fact that there's different licences (number of devices allowed for a book, etc.) for different eBooks/publishers.
