A SIMPLE AND VERSATILE PUNCH CARD SYSTEM FOR BIBLIOGRAPHIC USE.
Abstract
A punch card system is described which should find application for general or specific bibliographic use. The system enables the individual to file a reference by subject, author and year. A reference can be cross-indexed in as many as four subject categories and up to 39,999 subjects can be indexed. The cards can be filed randomly and, consequently, the system can be maintained with a minimum of labor. (Author)
