This paper describes research on the kinds of information needed by individuals in human service delivery and older persons' organizations. The Gerontological Information Program (GRIP) uses an integrated approach to gerontological information: research, systems development, and education. An information needs assessment questionnaire survey of 65 administrators and service providers in community agencies and organizations that deal with the elderly in Onondaga County, New York, shows that topical areas of information need vary between organizations, indicating that the current literature of many disciplines and professions needs to be searched for the purposes of GRIP. Based on the needs study and consultation with members of the gerontology community, the Gerontological Information System (GRIS) has developed two kinds of information services: current awareness service in the form of a newsletter, and on-demand information searches conducted using computerized retrieval systems, area libraries, and special collections. A graduate course which is an integral part of the program is described. Tables depicting questionnaire results and a bibliography are attached. (Author/KP)
