Abstract: There is disclosed herein a color-coded filing system for uniquely identifying documents to be filed and retrieved. The document to be filed has sequential filing characters applied along the top and side edges thereof. Marker tabs are provided which are pressure sensitive, adhesive-backed and transparent and have a colored peripheral border that defines a two-position transparent aperture. A positively applied filing character is provided in the first position of the tab aperture and the second position of the marker tab is blank. The marker tabs can be applied over the filing characters on said document so that the characters on the document appear in the second position of said aperture next to the characters on the tab. Both characters are of a similar size, color and shape so as to provide a unique and visually acceptable identification for said document. The filing characters can be either numerals or letters which can be used on the top or side edge of the document for drawer or shelf filing.

Abstract: A color coded indexing system to facilitate filing and retrieval of documents comprising two 10-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 10 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 10 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

Abstract: Set of ten strips of 10 two-digit color coded numerical indexing tabs, each strip comprising a backing of release paper and an overlying strip of transparent film having a coating of pressure-sensitive adhesive on its under surface mounted on the backing and cut transversely to devine ten individually separable tabs, the tabs of each strip being color coded by .[.reverse.].
