This book is both a collection of cutting-edge research in the areas of multilingualism, translanguaging and bilingual education by leading scholars in these fields, and a tribute to the research and influence of Ofelia Garca. The chapters use a variety of methodological approaches and research designs to address topics across language policy, sociology of language and bilingual education, representing the full breadth of Ofelia Garca's scholarship. Combined with the empirical chapters are more personal chapters which testify to the contributions Ofelia has made as a mentor, colleague and friend. The book recognizes Ofelia Garca's place at the centre of a movement to remake multilingualism in the service of linguistic equality, justice, pluralism, diversity and inclusion in schools and societies worldwide.
