"By uniting the linguistic, psycholinguistic, and sociolinguistic sides of language study, the authors succeed in offering an impressively comprehensive - yet concise - overview of the study of sign languages, and American Sign Language in particular. Lucidly written, full of illustrative examples, and complemented by well-selected discussion questions, the text is a perfect read for everyone interested in the basics of sign language linguistics."Roland Pfau, University of Amsterdam, The Netherlands
