The protocol is a rigorously tested web survey that helps libraries assess and improve library services, change organizational culture, and market the library. The goals of LibQUAL+ are to:
Since 2000, more than 1,340 libraries in 35 countries have participated in LibQUAL+, including college and university, community college, health sciences, and academic law libraries. This growing community of participants and its extensive data set of more than one million completed surveys are rich resources for improving library services.
