Book excerpt: By addressing these and other questions this volume proposes a critical guide to CA and its applications with an extraordinary interview with Emanuel A. Schegloff, and new contributions towards a debate on his work by six commentators - conversation analysts (John Heritage and Charles Goodwin), critics (Rick Iedema and Par Segerdahl) and appliers of CA in the study of human-computer interaction (Pirkko Raudaskoski) and language disorders (Ruth Lesser). Schegloff's Response and a closing discussion with the editors conclude the volume, which also features a comprehensive bibliography of his work edited by Susan Eerdmans.
