The ongoing expansion in the field of citizenship studies is one of the most important and remarkable recent trends in social sciences and humanities research. Some scholars raise questions about citizenship within a larger critique of liberalism and its institutions; others point to citizenship's inherently exclusionary nature. This volume examines_without advocating any ideological agenda_the evolving meaning of citizenship, with an eye to the future. The connected contributions_from the perspectives of anthropology, sociology, psychology, law, history, and other disciplines_examine four basic modes of citizenship in comparative global context: Differentiated, Divided, Dispersed, and Deterritorialized. The future of citizenship may, it is argued, come to rely on a global mode of "citizenship by association," tantamount to a worldwide civic interface.
