This is an authoritative collection of texts on language rights principles and practices as these have evolved over the past century, and their anchoring in international and national legislation. It is multidisciplinary, drawing on language policy, political theory, education, law, philosophy, anthropology, economics, minority studies, deaf studies, and indigenous cosmologies. The editors have written a general introduction, and introductions to each thematic volume. There are 95 key texts, case studies of language rights in many countries, written by scholars from all continents. The selection consists mainly of texts published earlier, some with updates, and a few specially commissioned chapters.
