When I'm downloading eBooks and Audiobooks in OverDrive, how do I know what format to choose?

The available OverDrive formats for eBooks, and Audiobooks, Music and Videos, are listed in this format chart. Look for the device you’ll be using to listen to or read the title, and then choose the appropriate format.

If a title isn’t offered in a particular format, that’s because the publisher hasn’t made it available in that format.
