Penguin eBooks
As of February 10, 2012 eBooks that are 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 link with some helpful instructions: http://www.amazon.com/kindletransfer 🙂
