As of February 10, 2012 eBooks published by Penguin loaned for reading on Kindle devices will need to be downloaded to a computer and then transferred to the device over USB. For library patrons, this means Penguin eBooks borrowed through the library Overdrive subscription will no longer be available for over-the-air (wireless) delivery to Kindle devices or to Kindle apps. Here is a handy URL to help you find instructions on how to do this on your particular Kindle model: http://www.amazon.com/kindletransfer
