Abstract: For use in a multi-page book, an index system comprising elongated flat transparent plastic index tabs each affixed by a strip of transparent adhesive tape. The tab overlies one edge of an associated page, projecting slightly outward therefrom so as to present an indicia bearing end and projecting a substantially greater distance inwardly thereof, terminating in an inner end. The transparent adhesive tape overlies the inner end, overlapping both the adjacent inner portion of the tab and the page face, providing a point of attachment substantially inward of the page edge. Removal of the tab for reuse is effected by a rotation of the tab about the adhesively secured inner edge, partially peeling the tape back so as to enable a complete exposure of the tab and a twisting removal thereof from the tape, the tape subsequently being reapplied to the page.
