A SYSTEM FOR CATALOGING REFERENCE MATERIAL,
RAND CORP SANTA MONICA CALIF
Pagination or Media Count:
The needle-sort card system for cataloging reference material is discussed. By this system, reports are cataloged according to subject matter by notching out appropriate holes that line the four edges of a card. The sorting process is then accomplished by inserting a needle into the proper row of holes in a deck of such cards, thus permitting the notched cards to separate from the deck. This permits a quick examination of an itimized summary of all available reports that might be of interest.
