The book *The Handbook of Conversation Analysis* edited by Jack Sidnell and Tanya Stivers is an excellent reference for specialists and students in sociolinguistics, ethnolinguistics, and sociological and psychological studies that use conversational interaction as a means to study social actions. The volume presents a selection of articles organized into five parts, with chapters written by renowned conversation analysts (CA) primarily from Europe and the United States. The articles exemplify the theoretical applications discussed and include a section on future directions. In the introduction, Stivers and Sidnell discuss the principles of CA, its interdisciplinary origins, and its main objectives. They also propose that the volume ratifies the validity of Sacks, Schegloff, and Jefferson's work in establishing CA as a discipline. The first section, "Studying Social Interaction from a CA Perspective," presents the principles of conversation analysis through four articles. These articles cover the intellectual roots and contexts of CA, the approach to data collection, transcription, and basic methods. The second section, "Fundamental Structures of Conversation," consists of eight chapters that outline conversational structures and what is known about them. These chapters discuss action formation, turn design, turn-constructional units, turn allocation, sequence organization, preference, repair, and overall structural organization. The third section, "Key Topics in CA," addresses various themes in the discipline, including embodied action, gaze in conversation, emotions, affiliation, epistemics, question design, response design, reference, phonetics and prosody, grammar, storytelling, and key contexts of study. The fourth section, "Key Contexts of Study in CA: Populations and Settings," explores the application of CA in different social contexts, such as interactions among children, atypical populations, psychoteraphy, medicine, classrooms, and courts. The fifth section, "CA Across the Disciplines," examines the relationship between CA and other disciplines, including sociology, communication, anthropology, psychology, and linguistics. It highlights the cross-fertilization between CA and these fields, discussing the contributions and influences of each discipline on CA. Overall, the book provides a comprehensive overview of conversation analysis, covering its theoretical foundations, methodological approaches, and applications in various social contexts and disciplines.The book *The Handbook of Conversation Analysis* edited by Jack Sidnell and Tanya Stivers is an excellent reference for specialists and students in sociolinguistics, ethnolinguistics, and sociological and psychological studies that use conversational interaction as a means to study social actions.
