Abstract
AbstractThe development of a low‐cost library control system for visual aids based on punch cards is described. Miniature pictures of the visual aids are printed on the cards with a Xerox 914 Office Copier, identifying information is keypunched, and additional information is entered by typewriter An inventory of other forms of the visual aid, such as glossy photographs, slides, and VuGraphs, is indicated by check marks on a small form printed on the card. The cards are designed to permit updating by additional punching as well as by overpunching previously punched symbols. The punched data is used by a computer to prepare indexes to the visual aid collection, and the cards themselves are used as a manual card catalog for everyday retrieval of visual aids.
