This analysis of tasks that search intermediaries performed to facilitate information exchange in presearch interviews with requesters of computer-based literature searches was part of a larger study that gathered data on 80 presearch interviews in seven medical libraries. The study also sought to identify verbal and nonverbal behaviors that facilitate, maintain, or impede information exchange and to objectively code videotaped presearch interviews in terms of the extent to which the librarian's tasks were accomplished. Chapters discuss the methodology for data collection, data analysis, requester satisfaction scores, personal variables, and study conclusions. Twenty-one references are listed, and tables display the data. (FM)
