I was on the Hawaii State Library website today and happened upon their Digital Book
page. It's a service powered by overdrive.com. It allows you to borrow e-books and CDs for three weeks at a time. So far I've checked out books about doing business in China and website design technique. And I'm listening to some Beethoven right now, too.
For books, it uses the Adobe Digital Editions program. You use OverDrive's Media Console to listen to CDs.
A valid Hawaii library card is required.
