A survey of 96 academic libraries belonging to the Association of Research Libraries reveals that the popularity of the four primary electronic reference mediums - online public access catalogs (OPACs), CD-ROM, end-user online and intermediary online - increased between 1991 and 1994. All the libraries provide CD-ROM access. Ninety-five provide intermediary online searching; 63, end-user online searching; and 71, tape loaded databases through OPACs.
