Yes, audio books can be put on the NC easily. I use Overdrive from the library (listennj.com) in NJ. Just have to have a library card that is up to date. Download Overdrive to your computer then find mp3 audio book from library and download it to Overdrive. Plug in NC to computer and click transfer tab. Audio book will be in music app. You can plug a speaker into headphone jack, or BN sells an audio wire that can go from NC to a speaker in port.
