This new edition has made several improvements over the last one. The organization is clearer and better prepared. This book provides a better explanation and more detailed examples than other books of this type. The CD is a great asset for readers in comprehending the heirarchy of crystal organization and provides better visualization of the three-dimensional aspects of the various crystal forms and structures.
