This English version of A Language in Space: The Story of Israeli Sign Language, which received the Bahat Award for most outstanding book for a general audience in its Hebrew edition, is an introduction to sign language using Israeli Sign Language (ISL) as a model. Authors Irit Meir and Wendy Sandler offer a glimpse into a number of fascinating descriptions of the ISL community to which linguists and other researchers may not have access. An underlying premise of the book is that language is a mental system with universal properties, and that language lives through people. A clear and engaging read, A Language in Space addresses relevant aspects of sign language, including the most abstract questions and matters related to society and community. Divided into three parts, the book covers: the linguistic structure of Israeli Sign Language; the language and its community; and a broad depiction of ISL and the contribution of sign language research to linguistic theory. This book is intended for linguists (with or without a background in sign language), psychologists, sociologists, educators, students, and anyone with an interest in the human capacity for language.
