It's fabulous, isn't it, riptide? I am a member of three different counties' libraries so borrow a lot of books every month. Mine don't use Libby, they use another app but all the apps are easy to use.
I download my eBooks on to my Kobo and Kindle as I prefer them to using my phone or tablet.
Shivvy, this is an idea of the public library service

Your local library may use different apps. You can reserve ebooks and audiobooks, too.
Great choice of audiobooks, too.
