Amazon will be offering Kindle Library Lending later this year. It allows all Kindle customers borrow Kindle books from more than 11,000 libraries in the US. The e-tailer partnered with OverDrive, which works with public and educational libraries to deliver more than 400,000 digital books. You don't have to use a Kindle reading device to borrow ebooks, you can use Kindle application for PC, Android, iPad, iPod Touch, iPhone, Windows Phone, BlackBerry, Mac.

Checked out ebooks are accessible by a reader during two weeks, then they become locked and inaccessible. Annotations and bookmarks can be made to a digital book borrowed from Amazon, but those notes won't appear to the next person that checks out the same ebook.

If you decide to purchase the same book or check it out from the digital library again, all of the notes will be restored.

Although it is not a subscription service, it is a great way to gain access to more than 400,000 ebooks.
