The control and inventory of property items using data processing machines requires a form of numerical description or code which will allow a maximum of description in a minimum of space on the data card. An adaptation of a standard industrial classification system is given to cover any expendable warehouse item or non-expendable piece of equipment. Items which are covered include--(1) textile, fabrics, apparel, (2) lumber and wood products, (3) furniture and fixtures, (4) paper and allied products, (5) chemicals and paint, (6) stone, clay, and glass, (7) fabricated metal products, (8) machinery and electrical, (9) instruments, and (10) musical, toys, and sports. A ten-digit number allows breakdown into specific items or classes with descriptive information identified. The identification of style, size, color, material, and manufacturers' flexibility is incorporated to allow for a maximum description of the items of equipment considered. (MM)
