This reference complements other American Sign Language (ASL) dictionaries by organizing signs by handshape rather than alphabetically by English word order. In so doing, it acts best as a recognition tool for the ASL learner, leading the user quickly to specific signs without having first to refer to an English-equivalent word. Multiple meanings of a single sign also allow deaf people to increase their English vocabulary. Like other ASL dictionaries, introductory material includes a brief synopsis of the history of sign language, the meaning and importance of the five parameters of a sign (handshape, orientation, location, movement, and nonmanual signals), grammatical rules, sign language variations (dialects), and finger-spelling principles. Tennant, a former mathematics instructor, and Gluszak Brown, a certified ASL interpreter, have provided a unique organization in their dictionary. But readers should note that a handshape is not a sign itself but rather a characteristic of a particular sign. Each individual sign presented in this dictionary is illustrated, paired with English-equivalent meaning(s), and described in terms of the five parameters, making it useful as a teaching reference as well as a recognition tool. A worthwhile complement to a public or academic library collection.?Andy Wickens, Univ. of Washington, Seattle
