> You don’t own the book. You cannot lend the book. Renting Kindle-compatible eBooks from the library is arduous and limited by artificial constraints; you literally need to return a book before another person can rent it.
The first thing I do when I buy or borrow a book from Amazon is strip the DRM. I don't share the DRM-free file with anyone - it's just for me - but it lets me read when and where I want.
Fortunately, the Kindle version can be simplified greatly and doesn't quite require the complexity of the other means.
