A holder for a book, such as a paperback or hard cover book, comprises a stiff flat member creased to provide a central stationary panel corresponding to the spine of the book, and a pair of pivoted panels corresponding to the front and back of the book. A spring assembly comprises a plurality of long concave thin metal members connected together by a strip of tape and connected to the stiff flat member by a pop rivet. The ends of the springs are received by a pair of plastic sleeves which are stitched to the stiff flat member. The stiff flat member is covered by a vinyl sheet in such a way as to have a curved edge providing a radius of at least +E,fra 1/16+EE ''. A transparent strap connects to the opposite sides of the book holder and presses open pages of the book against the flat stiff member. The curved edge prevents the transparent strap from being cut by the book holder.
