Bringing together a highly diverse body of scholars, this comprehensive Research Handbook explores recent developments at the intersection of international law, sociology and social theory. It showcases a wide range of methodologies and approaches, including those inspired by traditional social thought as well as less familiar literature, including computational linguistics, performance theory and economic sociology. The Research Handbook highlights anew the potential contribution of sociological methods and theories to the study of international law, and illustrates their use in the examination of contemporary problems of practical interest to international lawyers.
