What Libraries Are

There's a conference for academic libraries being held November 1-2 in Saratoga Springs. I want to note the theme of the conference is taken from the Talis White Paper in which four principles are addressed:
The library is everywhere;
The library has no barriers:
The library invites participation;
The library uses flexible, best-of-breed systems.

Don't think of libraries as just the buildings, but as the services provided.
