Today Amazon quietly rolled out a feature that lets Kindle owners share Kindle ebooks:

• Eligible Kindle books can be loaned once for a period of 14 days.

• The borrower does not need to own a Kindle — Kindle books can also be read using our free Kindle reading applications for PC, Mac, iOS, etc.

• Not all books are lendable.

The biggest catch is that once you lend a book, you can’t read it for the 14-day period, as with a printed copy.
