Following an A-Z format, the entries defined and discussed are drawn from the following areas: the 'old' social movements of the nineteenth century
the 'new' social movements of the 1960s and 1970s
the rise of contemporary 'network' movements.

Key American, European and global social movements are addressed, with each entry related to contemporary developments and emergent tendencies within the field. Including helpful references for further study, this concise and up-to-date guide is of relevance for those studying a range of disciplines, including sociology, politics, cultural studies and human geography.
