One of my favorite speaking teams in the library world are George and Joan. For those of you who have not heard them, George Needem and Joan Frye Williams are beyond forward thinking. If new thinking is "outside the box" these two are outside the box on the next planet. They have disciplined themselves to analyze each part of the library world and consider if it is ready for the future? Does it welcome the public, does it really serve the library's mission? They mix in humor and I, for one, am never disappointed with their message.
As an example, one of their recent blog posts shows how to take even a simple thing and make it positive. How many of us have put up signs asking folks to not eat in a certain area of the building? No Food please, please do not have food at the computer, etc. . . here is their recommendation.
