ABSTRACT : This exploratory study considered the problem of assessing quality in academic libraries. The research question that framed the investigation asked whether service quality scores from the LibQUAL+™ instrument were related to the following college or university characteristics: institutional type, enrollment level, or the level of investment made in libraries. Data regarding Carnegie classification, FTE enrollment, and library expenditures were collected for 159 college and university libraries that participated in LibQUAL+™ during 2006.
