'… designed to meet the needs of researchers, teachers, and students who want to keep up with the changing field … Baker and Brookes' groundbreaking book on language and identity is a valuable addition to the existing literature. It highlights language to use with advances in sociodemographic information and corpus-aided studies. The book is highly systematic, not only introducing major concepts but also contributing profound commentary and in-depth explanations regarding two different approaches and research methods of great importance.'
