Abstract: A notebook adapted for replacement of leaves has a helical binding coil disposed along a coil axis; a first cover leaf defining apertures along a binding edge; a second cover leaf defining apertures along a binding edge adjacent the binding edge of the first cover leaf; multiple leaves having coinciding apertures along associated edges, the spacing between apertures of the first and second cover leaves and the multiple leaves corresponding generally to spacing between turns of the coil; and an elongated handle element associated with one end of the coil and extending transverse to the coil axis. The handle element is adapted for rotation about the coil axis to advance the binding coil along the axis for engaging and disengaging the coil in apertures of the leaves. The handle may be secured to a cover leaf with the binding coil engaged in the apertures.
