Book excerpt: Documentary Resistance: Social Change and Participatory Media offers a new approach to understanding the networked capacity of documentary media to create public commons areas, crafting connections between unlikely interlocutors. In this process communities invest in the exchange of documentary moving image discourse around politics and social change. This book advances a new argument suggesting that documentary's capacity for social change is found in its ability to establish forms of collective identification and political agency capable of producing and sustaining activist media cultures. It advances the creation of a conceptual, theoretical, and historical space in which documentary and social change can be examined, drawing upon research in cinema, media, and communication studies as well as cultural theory to explore how political ideas move into participatory action. This book takes a distinctive approach, understanding how struggles for social justice are located, reflected, and represented on the documentary screen, but also in pre- and post-production processes. To address this living history, this project includes over sixty unpublished field interviews with documentary filmmakers, critics, funders, activists, and distributors.
