<p>COLOR CODED INDEXING SYSTEM A color coded indexing system to facilitate filing and retrieval of documents comprising two ten-position digital bars spaced longitudinally from each other on each opposed surface of an edge portion of each document and each successively displaying in its ten positions the numerals 0-9, with those on the obverse surface closely adjacent the document edge and those on the reverse surface offset inwardly from the edge; and ten sets of separable color coded single digit tabs with each set having a different color and displaying one of the digits 0-9 in two columns, the righthand column being closely adjacent the longitudinal center line of the strip and the lefthand column being offset laterally from that center line, and transparent windows to the right of each digit, each set being made up of a backing strip of release paper and a strip of transparent film having a coating of pressure sensitive adhesive on its under surface mounted on the backing strip and transversely cut through to the backing strip to provide a plurality of individually separable tabs; whereby adhering selected tabs over the proper digital positions of the bars and the space between the bars will transform the single digit tabs over the bars into double digit tabs to provide proper identification of the particular number of any document, the colors of the tabs over the bars identifying the ten thousands and tens digits, the color of the tab between the bars identifying the hundreds digit, and the digital positions of the tabs over the bars identifying the thousands and units digits of the document number, and proper filing of documents so identified will provide a color coded set position pattern for any desired filing system.</p> |
