Sociological Methodology is an annual volume on methods of research in the social sciences. Sponsored by the American Sociological Association, its mission is to disseminate material that advances empirical research in sociology and related disciplines. Chapters represent original methodological contributions, expository statements on and illustrations of recently developed techniques, and critical discussions of research practice. The volume is a valuable aid to the understanding and use of methodologies, providing techniques and perspectives on research that can be used to strengthen sociological and other types of social science reasoning. Each volume is a crucial addition to social research libraries world-wide and an important record of the current state of methodology.
