Top 10 LibQUAL+® Resources
Bruce Thompson, Texas A&M University and Baylor College of Medicine
A Google™ search on "LibQUAL+" yields approximately 100,000 hits, and more than 50 refereed journal articles have been published on the protocol. Given this wealth of information, it is hard to know what are the key resources for people to use to learn about LibQUAL+®, and how to use LibQUAL+® scores to improve library service quality. The page presents a subjectively-determined list of "Top Ten" resources for people interested in learning about LibQUAL+®. The resources are divided into sections: "before," "during," and "after" the implementation.
