Providing an authoritative and comprehensive overview of the classical and the contemporary, this volume is an indispensable guide to the vibrant and expanding field of sociology. Featuring over 600 entries, from concise definitions to discursive essays, written by leading international academics, the Dictionary offers a truly global perspective, examining both American and European traditions and approaches. Entries cover schools, theories, theorists and debates, with substantial articles on all key topics in the field. While recognising the richness of historical sociological traditions, the Dictionary also looks forward to new and evolving influences such as cultural change, genetics, globalization, information technologies, new wars and terrorism. Most entries incorporate references for further reading and a cross-referencing system enables easy access to related areas. This Dictionary is an invaluable reference work for students and academics alike and will help to define the field of sociology in years to come.
