This revised and updated edition provides not only simple, one-line definitions, but also entries that discuss the issues involved in, and alternative approaches to, the central concepts, theories and writings of sociology. It is a comprehensive reference for students of school to university level. For this edition, many new definitions have been added and existing ones updated where necessary. The range of entries is wide, from advertising to critical theory, from epistemology to flexible specialization and from Saussure to working-class conservatism. There are also useful cross-references and an updated bibliography to enhance the balance to this book.
