Understanding Occupy from Wall Street to Portland is strongest in chapters where contributors closely follow the contours of Occupy Portland to deliver ethnography-derived insight into the Occupy movement and the immediate environment within which it operated. . . .For communication, political science, or social movement scholars or students, as for those who are now continuing Occupy’s work in other arenas, Understanding Occupy from Wall Street to Portland presents a useful sociological description of Occupy Portland and its communication and consensus-building successes, as well as a cogent analysis of some of the rewards and challenges that accompany Occupy’s participatory, leaderless model of social movement organizing.
