A holder for holding a plurality of sheets formed with holes adjacent at least one of their edges, comprising: a backing member; at least one slide slidable along each end of a track extending along the width of the upper end of the backing member; and a cord or pair of cords carried by at least one slide and receivable through the openings of a plurality of sheets. The cords include mating connectors at one end to permit the plurality of sheets to be secured together, while the opposite ends of the cords are secured to a length-varying device enabling the effective lengths of the cords to be varied according to the number of sheets to be secured by the cords. In one described embodiment, the length-varying device is a "Velcro" hook and loop fastener; and in a second described embodiment, it is a reel.
