Career Key is a microcomputer library management system designed to access the cataloging records of the Career Development Library at Florida State University. The Career Key system, which provides access to a comprehensive and integrated multi-media collection of about 1,500 career resources, is based on a classification system involving 35 subject headings in the following subject areas: career planning, occupational information, educational opportunities, work experience and training, job hunting skills, and career placement. A tool for both subject retrieval and maintenance of library records, the Career Key system allows for the performance of five separate library functions--entering new documents, updating old document entries, updating codes, reporting, and subject referral. Thus far, client and staff responses to the Career Key have been positive. Because the system provides a centralized, compact indexing system to the library's entire career resource collection, it has eliminated the need for maintaining numerous sets of catalog cards and commercial indexes. In addition, the computer-generated printout of relevant library resources has provided a convenient guide for clients and has allowed for the more efficient use of professional staff time. (MN)
