A notebook insert that includes a housing including a first rigid substantially flat plate having a first set of a plurality of spaced holes formed therethrough a first side thereof. The first set of holes is adapted for engagement with the rings of a ringed notebook. The first rigid flat plate further has a second set of a plurality of spaced, stepped holes formed therethrough a second side thereof. The housing further includes an opening in a central portion thereof and a plurality of spaced hinges. The hinges are located on a side edge of the central portion defined by the opening. A second rigid plate has a first side hingedly connected via the spaced hinges to the first rigid plate. The second plate has a shape substantially matching the shape of the central opening so when the second rigid plate is in a stowed position it may be supported within the central opening. The second plate includes spaced projections formed on an upper surface thereof. The projections are so sized and spaced to align with the second set of spaced holes in the first plate when the second plate is rotated away from the stowed position so as to provide a holepunching capability when paper is inserted between an upper surface of the first plate and the second plate. The stepped holes have increased diameters at lower surfaces thereof that allow chads to be cleanly and easily be punched therethrough and released from the stepped holes when the second rigid plate is rotated away after punching paper. The stepped holes provide enhanced ease in disengaging the second rigid plate from the first rigid plate when rotating it back into position.
