National services provided by the Health Sciences Resource Centre of Canada

The Health Sciences Resource Centre forms part of the National Science Library of Canada, whose collections and services are described. The new Centre coordinates activities of the various provincial medical libraries. Its creation began with increased collections of medical journals, and plans are underway to print out a union list of medical journals from the Union List of Scientific Serials tapes. The first product of the Centre is a medical "proceedings index" to proceedings held by the National Science Library; this is computer-produced, and will appear annually. An analysis was made of the medical items requested for borrowing from the National Science Library according to type of material, service provided, type of user, and geographical location. The results are given.A description is given of the SDI service currently provided by the National Science Library, based on Chemical Titles, Chemical Abstracts Condensates, INSPEC, and the ISI tapes. It is hoped to expand this data base with MEDLARS tapes.
