What is the checkout period for eAudiobooks?
eAudiobooks come with a license that is good for 21 days. You can renew any eAudiobook once for an additional 21 days from your NetLibrary account without downloading the file again. After the 21 days, the license expires and the file will no longer play. The file remains on your computer/device, so you should manually delete the file when you are through listening to it, to save space.
