Abstract: The Book Holder Support Stand holds a book receiver which permits a person to read in many positions. The orientation of the book receiver attached to the stand can be adjusted with a single control. The invention is counterbalanced to permit substantial overhang, allowing the book holder to be placed close to furniture that extends down to the floor. It may be rolled around easily and can be carried up and down stairs using one hand.
