Social science has taken a noticeable turn, with new energy infusing the study of social mechanisms and causal processes that unite the classic micro-macro divide. The Oxford Handbook of Analytical Sociology, edited by Peter Hedström and Peter Bearman, is an impressive effort to guide the research agendas sure to follow. The volume is a comprehensive intellectual treat and an indispensible tool for sociologists seeking to master the analytic turn. Professor Robert J. Sampson, Harvard University 25/10/2010
