The Johnson solids, named for Norman Johnson, who was the first to catalog them, are all the convex polyhedra with regular polygons as faces, excluding the Platonic and Archimedean solids and the prisms and antiprisms. Most of the data in this book can be found elsewhere, but this is to my knowledge the first attempt ro collect them all in one place. In addition, this book also collects the corresponding data on the duals of the 92 Johnson solids, information which is difficult to find elsewhere.
