Hands down, one of my favorite apps is Overdrive.
I love to read and, lately, I've been driving back and forth from New Orleans so I had been paying extra to get the Audible sync to the books I was reading.
But I go through them quickly and that can get to be a bit pricey. Then I remembered I could borrow audioboks from the library and that I already had Overdrive set up with my library card. I knew all the current bestsellers would be waitlisted so I pulled up bestseller lists from previous years and started downloading all those I'd missed. I am SO winning here! GO ME!
What app do you use to borrow eBooks and Audiobooks from your library? If you don't borrow books from your library...why is that?
