a different performance indicator for libraries?

Maybe a better qualitative measure for libraries and standard of success is to record the extent of a library's pervasiveness within the electronic or digital environment in conjunction with standard resource and service based statistics? We are discovering that quantitative measures for resources have their use but their actual relevance and thus a library's relevance is increasingly dependent on users finding and easily accessing these resources. This assumes as you add a presence AND PROMOTE it in an electronic environment, the stats for resources and services should increase.

Thus a library should perhaps document the different places and ways they make their resources and services available electronically - the learning management system, the student portal and the faculty portal, the document management process at a university, the library website, faculty and departmental websites, google scholar, facebook, second life - you get the idea. They should also develop a program of promoting these resources. The stats would then reflect a collated measure of success in that environment and thus the library's success. I suspect I'm stating the obvious.
