Abstract
Abstract A collapsible stand for supporting a book in an inclined readable position. The stand includes a base member having rearwardly extending side walls provided with slots therein. A planar book rest extends upwardly from the base member. A flexible bracket is connected between the base member and the book rest for supporting the book rest at a desired reading angle. The flexible bracket also permits the book rest to be folded down within the base member into a compact package for carrying.
