Eric Livingston 
Ethnographies of Reason [PDF ebook] 

Written by one of the most eminent scholars in the field, Ethnographies of Reason is a unique book in terms of the studies it presents, the perspective it develops and the research techniques it illustrates. Using concrete case study materials throughout, Eric Livingston offers a fundamentally different, ethnographic approach to the study of skill and reasoning. At the same time, he addresses a much neglected topic in the literature, illustrating practical techniques of ethnomethodological research and showing how such studies are actually conducted. The book is a major contribution to ethnomethodology, to social science methodology and to the study of skill and reasoning more generally.
