Subject heading authority list, computer prepared
William Way · American Documentation · 1968
Abstract A Subject Heading Authority List containing main entries, scope notes, cross‐references, and subdivisions is compiled, printed, and updated by computer. A code‐sort method preserves the Library of Congress format of the subject headings and allows for random insertion and deletion of entries. The master tape and updated punched cards are used to produce biweekly change notices plus a quarterly revision of the list. Design criteria, programing, input preparation, printing, and future refinements of the list technique are covered. Selection from among several design alternatives is emphasized.
