Mechanization of Cataloging Procedures *

  • Articles


The Columbia-Harvard-Yale Medical Libraries Computerization Project has put into operation its mechanized procedure for the production of catalog cards. Cards produced are in final form ready to be filed into a card catalog. Catalogers prepare copy on a worksheet from which punched cards are punched. An IBM 1401 computer processes the decklets of punched cards on magnetic tape to produce the expanded decklets of punched cards needed to print the various packs of catalog cards required to go into different catalogs. Next, the computer punches the expanded decklets of cards to operate an 870 Document Writer, which types out the catalog cards in final form. Cost of cards ready to file is 12.5 cents per card.
