Library Journal's annual list of America’s Star Libraries...
From Library Journal:
Here we will explore what some of this year’s Star Libraries are doing with outcome measures, chiefly through their involvement with up-and-running projects such as the Edge Initiative and the Impact Survey, as well as developing efforts—for example, the work of the Public Library Association (PLA) Performance Measures Task Force. Comments were solicited from directors and other representatives of Star Libraries about how their experiences with outcome measurement affect their views about where public libraries need to go with output measurement.
