The Nuclear Safety Information Center serves the nuclear community by collecting, storing, evaluating, and disseminating safety information relevant to the design and operation of nuclear facilities. In 1964, after about a year of operation, the information-handling system was computerized in order to increase broadly the scope of the Center's services and enable efficient functioning in the future. Computer programs were developed for the preparation of a bibliography, complete with key-words and personal author indexes, that is issued quarterly and for a program of selective dissemination of information (SDI) that is produced on 5 × 8 in. cards. These programs and other services of the Center are discussed.
