A book rack has two side walls and a rack extending between the side walls. The side walls each include a core made of a lightweight structural material, such as corrugated or honeycombed paperboard, a coating which coverers inner and outer surfaces of the core, and an edge bead covering an edge of the core. The rack comprises a single sheet of substantially transparent material formed generally as a wave defining a plurality of valleys. Each valley has a forward wall and a rear wall. The sheet is formed such that the a valley is positioned above and behind a preceding valley so that the books which are placed in the valleys will be easily visible.
