This study developed an analytical approach to detecting groups with homogenous usage patterns in a Web-based information system. Principal component analysis was used for data reduction, cluster analysis for categorizing usage into groups. The methodology was demonstrated and tested using two independent samples of user sessions from the…

Designed for use by study coordinators, library supervisors, and data collectors, this manual is the basic reference and training document from the 1982 field survey of public online catalog users and nonusers in 31 U.S. research, academic, community college, public, and governmental libraries. The field survey was coordinated by the Research…
