- (e) said journals having limits of rotation when said second surface is in planar contact with said arms, said configuration extending beyond said support when said journals are at said limits of rotation.
- 2. The notebook insert of claim 1 wherein said notebook includes at least two axially-aligned, openable rings spaced longitudinally along said spine and said configuration includes said center portion having a plurality of openings for receiving said rings.
- 3. The notebook insert of claim 1 wherein said spine includes a helical coil with loops and said configuration includes said center portion having catches for projecting through said loops and for prevention of inadvertent removal from said loops.
- 4. The notebook insert of claim 1 wherein said outer bearing is located on a center line of said second support surface.
- 5. The notebook insert of claim 1 wherein at least a portion of said first surface is smooth.

- 11. The notebook insert of claim 1 wherein at least said first surface includes at least one compartment.
- 12. A notebook insert for use in a notebook having a front cover and a back cover hingedly connected to an elongated spine, said notebook insert comprising:
- (a) a C-shaped frame having a center portion and a pair of equal-length arms, each of said arms having at least one notch at an end remote from said center portion and said center portion including a configuration for connecting said notebook insert to said spine;
- (b) a support having a first surface and a second surface, at least a portion of said first surface being smooth, said support being pivotally connected to said frame by at least two axially-aligned journals, each of said journals including an inner bearing surface and an outer bearing surface;
- (c) said inner bearing surface being the surface of a cylinder extending between opposed edges of said notch;
- (d) said outer bearing surface being the inner surface of a substantially cylindrical depression located in a protrusion on a center line of said second surface, the cross-section of said cylindrical depression forming an arc that retains said cylinder; and
- (e) said journals having limits of rotation when said second surface is in planar contact with said arms, said configuration extending beyond said support when said journals are at said limits of rotation.
- 13. The notebook insert of claim 12 wherein said notebook includes at least two axially-aligned, openable rings spaced longitudinally along said spine and said configuration includes said center portion having a plurality of openings for receiving said rings.
- 14. The notebook insert of claim 12 wherein said spine includes a helical coil with loops and said configuration includes said center portion having catches for projecting through said loops and for prevention of inadvertent removal from said loops.
- 15. The notebook insert of claim 12 wherein at least said first surface includes a plurality of clips.
- 16. The notebook insert of claim 15 wherein said each of said plurality of clips includes a bent sheet of spring steel mounted to an edge of said support.
- 17. The notebook insert of claim 15 wherein each of said plurality of clips includes an aperture in said support and a finger extending from said support surface over said aperture.
