Overdrive?

I know there are passionate feelings in the library world regarding Overdrive these days.  I think libraries are trying to figure out the best way  to work in the digital world and I don't know that Overdrive is the best way.  But right now, I think it's the best way to start. 

Our district is trying to get an Overdrive account set up for our students.  It fits into our movement to a BYOD format since Overdrive covers multiple formats.  Also, they seem to have the most options of books available--although with Penguin's pull out, that might have changed.  I know some of the issues people have with Overdrive concern the publishers and there's nothing we can do about that right now.

I think, too, this move is something public and a highly visible way to show our district's libraries are cutting edge.  Not too many school districts are able to get into the program due to cost, but we might be able to pull it together right now.  The PR value alone is worth it in my mind.  I'm tired of feeling like people think we are an old antiquated institution.  Having an ebook subscription and promoting it relentlessly would go a long way to polish our image.

So if anyone out there in cyberspace has experience with Overdrive, I would love to hear what you think.  Any pros? cons?  What should my district consider before signing on the dotted line?  Please leave me some comments with your opinion.
