The usefulness of two computer-based guidance systems--SIGI (System of Interactive Guidance and Information) and ENCORE--in meeting the career planning needs of adults was explored. Another area of study was how these systems fit into the differing career resource centers of an employer, a college, and a public library. Participants who used SIGI at the NCR Management College and at a SIGI work station in the personnel resources office of an Ohio NCR division found the program helpful. Their comments confirmed the general demand for career development programs. Of the 51 people who used the ENCORE system at the Ursuline College Counseling Center, 27 were very pleased and 20 rated the system as "OK." SIGI users at other educational sites were very satisfied, although over half rated SIGI content as oriented toward a younger college student. The use of SIGI and ENCORE in public libraries in Cleveland and Columbus, Ohio was minimal and illustrated the need for a supporting program in terms of marketing, staff support, and follow-up services.
