DRM and eBook reading technology in libraries

Here is a presentation for librarians about one particular issue (DRM) that the boom in eReader technology is foregrounding.
A survey from HighWire Press of 138 librarians showed that DRM is one of the most pertinent issues around eBooks and eReading technologies.
Hopefully this presentation will get people thinking about this topic and providing feedback to vendors.
By all means feel free to add your thoughts and comments on the issue of DRM in eReader technology and how this positively or negatively affects your library service.
