American Sign Language

This is a revised dictionary of American sign language, introducing more than 1500 new signs and 4000 new illustrations. The 7000 signs in the book represent a large part of the ASL lexicon, and are supported by more than 10,000 illustrations of the hand, arm and facial motions that express each sign and allow the user to begin signing immediately. The dictionary includes signs which have recently come into vogue, such as "log on", "downtime" and "digital".
