This book, which emerges in the context of the European research network LINEE (Languages in a Network of European Excellence), is concerned with European multilingualism both as a political concept and as a social reality. It features cutting-edge studies by linguists and anthropologists who perceive multilingualism as a discursive phenomenon which can be revealed and analyzed through empirical fieldwork. The book presents a fresh perspective of European multilingualism as it takes the reader through key themes of social consciousness - identity, policy, education, economy - and relevant societal levels of organization (European, national, regional).
