According to Library Journal (

Quote:
The lending will be available for all generations of the Kindle as well as Kindle reading apps, and it will integrate with all the existing ebook catalogs in the United States powered by OverDrive. In other words, the libraries-including schools, colleges and public libraries-will not have to add a new format, and the ebooks now available on the OverDrive sites will be immediately integrated with the Kindle, Dan Stasiewski, a marketing associate with OverDrive, told LJ.
"There will be no additional cost to acquire new files to make them compatible," David Burleigh, OverDrive's director of marketing, told LJ.
