I downloaded OverDrive Media to my PC and then went to the Ohio Digital Library site for the books. Find what you want and then it will redirect you to your local library where you log in with your library card and borrow the title. When you are finished it will automatically be deleted from your PC after the given lending period or you can renew it once. I don't know about other libraries but something you could check out with them. Ours had a big presentation about all the different ways to find your reading material. Works great.

I also have overdriveve on my nook. I have only gone thru my local library for my books, I do not know if Michigan has a digital library or not but am going to check it out. Thanks for the post, I did not even think to check this out.
