Every now and then you might find yourself with an eBook or Audiobook that won't work with your device. It is possible to return the incompatible title to the collection immediately at your bookshelf immediately after checking out the title.
If you have a choice of forms, of course, always double-check the available formats. But if you notice your preferred format isn't available, don't "select and confirm." Look for the "Return Title" button below the format options. (Click on any image to enlarge.)
When there are no additional options, double-check the format before downloading. Notice the "Return Title" option? That option will disappear when you attempt the download the title.
If you accidentally select and confirm or try to download an incompatible format, many of the items can be returned early to the collection.
If you are not able to return the title yourself, contact your local librarian and ask that they submit a support ticket to OverDrive's tech support team
