<p>A book holder with a back plate (101), a transparent cover plate (106) movable relative to the back plate (101), and a connection between the back plate and the cover plate which permits the cover plate to move relative to the back plate so as to provide guided movement of the cover plate toward and away from the back plate in substantially co-planar relationship, whereby lateral support arms (110) are fixed relative to the cover plate (101), hollow receiver plates (112) are fixed relative to the back plate (101) and the hollow receiver plates are of such internal configuration as to enable the lateral support arms to slide therethrough. <IMAGE></p> |
