Community development is collective action by definition. The Catalog is our attempt to gather and organize the numerous individuals, organizations, legislation, and texts that have made a contribution to community-based development, design, and organizing. The catalog is meant to be a live database that grows over time as the movement continues to evolve. If there is an entry that you think should be included in the Catalog please email us at For terms, time periods, and movements that are not so easily categorized, please head to the glossary.
