This study of CUL's LibQUAL+ data was presented on May 21, 2008 at CUL's Professional Development Week. The PowerPoint file is located in CUL's eCommons: http://ecommons.library.cornell.edu/handle/1813/10842 . This report records the narrative of the presentation to help CUL colleagues better understand the many graphs in the PowerPoint. There were two goals for the study. First, we wanted to determine what longitudinal data could be mined from past LibQUAL+ surveys' core questions. Second, as CUL considers if and when it would like to administer the LibQUAL+ survey again, we wanted to get a sense from CUL staff of how useful that data is to their decision making processes. The study aimed to identify trends, as well as areas where CUL has done well, and where it needs improvement. CUL administered LibQUAL+ four times: in 2001, 2002, 2003 and again in 2005. The 2001 survey data was not included in this analysis due to the pilot nature of that year.
