The studies in this volume address novel technologies of instructed action and non-obvious ways in which ordinary actions turn out to be instructive for participants in immediate situations of action and interaction. In some cases, the studies address specialized practical, artistic, and recreational activities, and in others they address commonplace modes of action and interaction. In all cases, they focus on how the manifest organization of specific activities is organized with and without explicitly formulated instructions. This book will appeal to scholars across the social sciences with interests in ethnomethodological approaches to research by contributing to understandings of how specific actions are instructed and instructive in the circumstances in which they are produced.
