Comments:ALTERNATE EDITION: TEACHER EDITION SPIRAL BOUND. COMPONENTS ARE NOT INCLUDED. Heavy wear and creasing to cover/edges/corners. Cardboard showing on corners, edges and spine of book. Covers and some pages are beginning to detach from spiral binding, but still holding on. School markings on/inside covers. School markings/highlighting throughout book and black-out marks on edges of pages, but none that impairs usability. WE HAVE NUMEROUS COPIES.
