Overdrive, headquartered here in Cleveland OH, has a Digital Bookmobile, which is touring the US promoting it's books to libraries. Here's a link to their bookmobile site where you can get their tour schedule:

If it comes to your area, you should check it out!
On their pages is a section for Libraries to contact them:

Ya'll should urge your local libraries to take advantage of their service, as most libraries require residency to get library cards.
I'm very pleased with our own Cuyahoga County Library and it's selection of current eBook titles.
