DRM presents a barrier to access to library materials. To get an Overdrive audiobook on my laptop or Ipod, I have to have Windows (can't use a free, open source OS). I have to have ITunes, Windows Media Player, and the Overdrive Console installed and working properly. In my experience, this is almost never a straightforward process.
It's difficult for those who can't afford Windows or those with little or no technical expertise to access DRM-protected library content. Traditionally, libraries exist to help underserved populations, and DRM certainly doesn't help us do that.
A person could take a library book home and photocopy all the pages, or rip a library CD to their home computer; we don't institute rules requiring people to use library materials on the premises. I believe it should be up to each library customer to decide whether or not they are going to break the law.
Besides, if it's easier to grab a torrent of the ebook than go through the library's DRM hoops, what do you think people are going to do?
