A sheet holder includes a slide (6, 8) slidable along each end of a track (4) extending along the width of the upper end of a backing member (2), and a cord or pair of cords (10, 12) carried by at least one slide and receivable through the openings of a plurality of sheets. The cords include mating connectors (10a, 10b) at one end to permit the sheets to be secured together, while the opposite ends of the cords are secured to a length-varying device (16, 18) enabling the effective lengths of the cords to be varied according to number of sheets to be secured by the cords. |
