(1) Can someone, perhaps an Amazon employee, clarify if "loan once" means exactly what it says? Can we only loan a kindle book to one person one time only? The book cannot be loaned again to anyone? Or cannot be loaned again to the same person? (2) As an early adopter of Kindle, It's particularly sad that, as I peruse my Kindle collection, the vast majority of our books are not loanable. I can't say that I'm surprised. But I am annoyed by it. This is perhaps a large factor in the soft launch of the loaning feature.
