Four Categories of Academic Libraries: A Cluster Analysis Based on Collections, Expenditures, and Circulation per Student Data
Brady Daniel Lund · Library Collections Acquisitions and Technical Services · 2017
The purpose of this study is to determine whether hidden categories of academic libraries exist based on collections, circulations, and expenditures per student. This study utilizes k-means clustering analysis to identify categories of academic libraries based on three variables: number of library resources per enrolled students, library circulation per enrolled student, and library expenditures per enrolled student. Four distinct clusters are identified: high circulation per student, high expenditures per student, large collections per student, and standard circulation, expenditures, and collections. Attributes of these clusters of libraries (institution type, university endowment, year established) are explored. These findings indicate new means of classifying libraries based on funding and use statistics as opposed to characteristics of the institution of higher education which the library serves.
