Whether you’ve got a Xoom tablet, Droid phone, or one of those myriad gadgets that begin with a lowercase “i ,” downloading Library e-books onto your device is easy. All you need is the OverDrive Media Console app and, of course, a free Kansas City Public Library Card and PIN.
This video tutorial shows how to use the Library’s EPUB e-books collection, supplied by OverDrive, on your Internet-enabled mobile device. There's no need to come into the Library -- as long as you've got a connection, you can check out e-books from anywhere and begin reading them immediately.
For a complete list of devices that work with our e-books, visit the Device Resources Center at OverDrive.com . You will also need to create an Adobe ID  in order to check out books (this is because of publishers’ digital copyright restrictions). The video explains that, too.
