Abstract: A novel hanger binder for binding and storing perforated edge paper in conventional suspension filing systems. The hanger binders which are used in pairs have two side members with hooks to engage conventional suspension filing apparatus. Perforated edge paper is bound between the side members on a binding post and thereby supported without continuous support along the length of the paper.Two types of hanger binders are included. One made of wire with a rigid binding post. The other has a flexible binding post and greater variability of spacing to bind and store larger numbers of sheets.
