This report summarizes the proceedings of a conference that brought together 35 librarians, network representatives, and system vendors to exchange information on the training of users of online public access catalogs. Three papers are presented: "Historic Concerns in Library Instruction: Teaching the Card Catalog," by Evan Farber; "The Nationwide Computer Catalog Study: Training Issues," by Douglas Ferguson; and "Psychological Factors in Online Catalog Use, or Why Users Fail," by Christine L. Borgman. Also presented are summary descriptions of current online catalog user training programs at Northwestern University; Mankato State University; Pikes Peak Library; Dartmouth College; University of California, Berkeley; Iowa City Public Library; Guelph University; University of Illinois at Urbana-Champaign; and the Library of Congress. A transcript of a panel presentation on the communication between public service and systems staff in building the online catalog is followed by a brief summary of the conference, which focuses on its four main themes: communication, diversity versus standardization, system enhancements that facilitate user training, and the use of goal-oriented training versus the provision of a learning environment. Conference recommendations are also recorded. Appendices provide a list of conference participants, the conference agenda, and a list of handouts distributed to participants. (ESR)
