The Kindle announcement is essentially a format extension, not a new deal between libraries and Amazon that would add hundreds of thousands of books to OverDrive’s collection. In most cases, libraries can now offer their existing OverDrive ebook collections in Kindle format as well as PDF and EPUB.
This is pretty cool. When it was announced a few days ago, only Adobe files were showing up for my local library. Now it’s showing the Kindle versions, too. However, the “Add to Wish List” feature didn’t work for me in either Safari or Firefox.
