摘要：This paper reports the major findings of a questionnaire sent to the 708 U. S. and Canadian institutions which were using the National Library of Medicine's search services as of November 1977. Development of the National Library of Medicine (NLM) on-line network is traced. Summary data for a current profile of on-line usage characterizes type of institution, use of NLM and non-NLM data bases, operational service patterns, staffing levels, fee-for-service policies, and perceived impact.
