ABSTRACT:
A pad with an extended margin is disclosed which includes a backing member that is wider than a pad of paper which is attached to it. The resulting margin is provided with three holes receptive to the rings of a binder, and right angle slits connect the holes to the longitudinal edge of the margin extension. These slits permit the pad to be inserted and removed from the binder without opening or closing the rings of the binder. A retrofit extension margin is also described which can attach various items within a ring binder.
