Q. Can any of your e-books be played on a kindle? If yes, how can I tell which ones.

Yes you can!  Overdrive is compatible with the Kindle ereader, as well as several other ereaders and mobile devices (meaning every book that's available through Overdrive should be Kindle accessible).  You can take a look at our infoguides on how to get started with Overdrive and more specifically on using Overdrive on a Kindle for more information.
