Collaborative activities that reflect ‘ethnicity as provenance’ benefit from collaborative, interdependent relationships among archives, classroom, and community. Examples from Center for Colorado & the West at Auraria Library (University of Colorado Denver) and the Southern Colorado Ethnic Heritage and Diversity Archives and the Voices of Protest Oral History Project (Colorado State University-Pueblo) illustrate collection development practices that advance joint ownership of archival materials by the archives and the originating cultural population. Concluding reflections offer transferable principles for working collaboratively with cultural communities on creation, identification, interpretation, and preservation of photographs, videos, documents, oral histories and ephemeral material reflective of culture, achievements, conflict, and legacy.
