ABSTRACT:
A hardback book comprises a plurality of leaves connected together at the rear of the book so as to form a spine, and two rigid or semi-rigid cover boards covering the front and back leaves respectively. Each cover board projects rearwardly beyond the spine of the book when the book is closed and, preferably, beyond the edge of the spine by a distance which is approximately half the distance between the two longitudinal edges of the spine when the book is fully opened at its center on a flat surface.
