Hmm, I wonder if we'll get it in Hennepin (who's invested in OverDrive to the tune of 31,000+ titles) anytime soon. Of course it looks like it only works on PC's, Android & iOS devices or an eReader you go to the library and borrow so I'm not sure how interesting it'll be.
I see I can bring my library card in and get a card for St. Paul libraries. Might have to do that just to give it a try the next time I'm on that side of town.
