The spine also has a pair of facing short walls 102, 104 a top wall 102 and a bottom wall 104, in parallel relationship and at essentially right angles with respect to the front wall and rear wall. The top wall is located between the top of the front wall and the top of the rear wall. The bottom wall is located between the bottom of the front wall and the bottom of the rear wall. The long walls and short walls are in a generally rectilinear configuration with an open face 106 from which pages may extend and an opposed closed face 108 opposite from the open face. At least one elongated retainer 114 essentially spans the space between one pair of parallel walls and is adapted to receive and retain pages 124. The retainer has opposed ends 116, 118 with at least one end 116 coupled with respect to an associated wall. A plurality of pages 124 are included. Each page has an interior edge 126 positioned within the spine and coupled with respect to the retainer. Each page also has an exterior edge 130 extending outwardly from the spine in a direction away from the closed face.
