This glossary of key terms is a guide to changing meanings and issues in cultural studies and the broader study of culture. The entries present cultural theory as an active and continuing set of debates which challenge the received attitudes and redefine thinking. Cultural theory ranges across a number of academic disciplines and subject areas. There is hence no prescribed route through the glossary but a network of possibilities connecting readers with a wide terrain of on-going theory and discussion. Topics covered include: feminism, Marxism, psychoanalysis, poststructuralism, discourse, postmodernism, postcolonialism, media and popular culture, and sociology of culture and information theory.
