As an aid to office economy and the proper administration of business affairs, the card-index system stands as the greatest improvement over old methods that has been or ever can be introduced. Card systems enable a vast volume of work to be handled by low-priced help that formerly came within the province of high-salaried office workers, leaving the managers of a business free from many annoying problems of detail, and giving them time for other and larger matters.
Card systems are made up of record cards printed or ruled for receiving the proper records, arranged between guide cards which have edges projecting above the record cards. On these edges is printed or written the index matter necessary to locate readily any record card or cards desired. The cards stand on edge in drawers of convenient size. A single drawer may be complete in itself, may contain several complete systems, or may be part of a cabinet of any number of drawers desired.
