What's the Difference Between OverDrive, the Digital Media Zone, and Libby?


  • OverDrive is the company that built the platform that the Huntsville-Madison County Public Library and many other libraries worldwide use to lend eBooks and audiobooks. OverDrive also distributes and sells the content (eBooks and audiobooks) to libraries to check out.
  • The Digital Media Zone is the name that HMCPL gave to the OverDrive platform that we make available to HMCPL patrons. HMCPL is in a consortium group with the Florence-Lauderdale, Guntersville, and Oneonta Public Libraries. This is why you need to select your library when signing in. 
  • Libby is the name of the app from OverDrive. You can use Libby on your phone or other device to access the Digital Media Zone, checkout titles, and read or listen to your checkouts. 
  • Whether you are in OverDrive or Libby, both will connect to the Digital Media Zone collection.
  • For this guide, we will use "Digital Media Zone" when referring to this resource.
