A number of large information systems operating in countries other than Canada were investigated. Some of these systems or combinations of them can be used as models for pilot applications in Canada. Some research and considerable development are required, however, to enable them to meet specific Canadian requirements. To create regional and national networks of systems, Canada must increase research in information science. Further education and training of librarians, information specialists, and users are needed to cope with the extensive changes in staffing and organization of scientific and technical information (STI) services. Standardization in the methods and procedures for indexing, coding, storage and retrieval of STI are essential for national and international exchange of information. Canada provides less than three per cent of the world's STI, therefore, she should be seriously concerned with developing systems that can utilize information from many sources. Active participation in international standardization bodies is necessary to assist Canada in developing STI systems that will be compatible with systems in other countries. Recommendations from the study are listed. (Author/NH)
