Top 10 LibQUAL+® Resources

Bruce Thompson, Texas A&M University and Baylor College of Medicine

A Google search on "LibQUAL+" yields approximately 50,000 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.

  • Sample LibQUAL+ Results Notebook
    This PDF download is an example of one of the major deliverables that each institution receives after LibQUAL+ has been implemented. Participants also receive their quantitative data in .csv files, SPSS syntax files, and the open-ended qualitative comments.
  • Self-Paced Flash Tutorial
    This tutorial explains the "zones of tolerance" rating system, the three basic dimensions of service quality measured by LibQUAL+, and how to read some of the charts used to report results.
