The Organizational records series contains primary source materials from Mike Miller's entire career as a community organizer. Of particular interest are the subseries for the Mission Coalition Organization (MCO), La Guardia Tenants' Association (LGTA) and other housing organizations, All Peoples' Coalition (APC), and San Francisco Organizing Project (SFOP), which contain large concentrations of correspondence, bylaws, petitions, polls, newsletters, fliers, meeting minutes, tenant interviews, and ephemera. These subseries present an unusually complete snapshot of community self-definition and advocacy. The subseries "Christians Supporting Community Organizing (CSCO) and other Marilyn Stranske projects" collects extensive materials related to Miller's colleague, the Evangelical organizer Marilyn Stranske, and her lifelong mission of faith-based advocacy. The ORGANIZE! Training Center (OTC) subseries is the largest of the group, and collects materials pertaining to Miller's organizing workshops and other training activities, as well as various administrative files.
