OverDrive is a collection of downloadable ebooks and audiobooks. Libby is the name of the app for using OverDrive on mobile devices.
You can use the Access link below to sign in and borrow from OverDrive.
Or, you can sign in using "My Account" to search and browse the library's catalog. You'll see buttons for "Check Out OverDrive" or "Place Hold OverDrive" for any downloadables. Then follow through to read with Kindle, Libby, or an EPUB reader.
The Libby app is an option for smart phones and tablets. You can also use Libby in a web browser without installing the app.
