Mar-Molinero brings together a set of outstanding contributions which move us forward in our understanding of multilingualism in superdiverse urban contexts. The emphasis on methods and research reflexivity makes the volume a very useful tool for investigating language in some of the major cities in Latin America, France and the UK. * Melissa Moyer, Universitat Autņnoma de Barcelona, Spain * In its timely exploration of the relationship between urban multilingualism and transnational migration, this volume underlines the importance of interrogating the boundaries of the city and of language itself. Drawing on a wide range of multimodal and ethnographically informed methodologies, the contributors provide particularly insightful reflections on the role, repertoire and positionality of the researcher, which make this book a compelling and thought-provoking read for sociolinguists at all career stages. * Kristine Horner, University of Sheffield, UK * This book is a much-needed addition to the expanding literature on multilingualism in the city. It offers fascinating accounts of the sociolinguistic situations in a range of communities. It also develops innovative methodological approaches that will be very useful for future research on linguistic superdiversity in urban contexts. * Li Wei, University College London, UK * This edited volume is invaluable in many ways [ ...] With insightful methodological problem-solving, the authors in this volume unveil the sociological and anthropological foundations of language use and revitalize understandings of identity construction, linguistic ideologies, and broader power dynamics that emerge with language usages. Upon reading the book, one will discover it offers more insights than those this brief review honours. -- Cristina Lacomba, Harvard University, USA * Ethnic and Racial Studies, 2021 *
