This thirty-eighth volume of the People’s Linguistic Survey of India is devoted to the Indian Sign Language (ISL), the language of the Deaf in India. The articles in the volume are divided into four parts. The first discusses both its formal linguistic and ‘orthographic’ features; the second presents the sociolinguistic themes of the ISL such as bilingualism and language variety as well as language planning and policy issues. Part three presents various synchronic aspects of the ISL. The final part comprises articles on themes interfacing Sign Languages and other knowledge systems. This very first collection of articles on the ISL, is a critically important contribution to the discipline.
