I would argue that a library’s mission (again, generally stated) is to provide access and serve users—it might not require complete change, but perhaps a reinterpretation. The library’s job has always been to be of assistance to patrons, but as patrons change, we too must continue to serve them.

So why don’t some libraries feel they need to change?

I like the idea of theory to practice and your idea and a smile will go a long way, especially when combined with some concrete ideas of how to use the technology to satisfy a real need as illustrated in your previous post.
