This article traces the divergent reception of a museum catalog I co-authored at the outset of my career as a case study to explore shifting paradigms of museum practice in the 20th and 21st centuries. Reconsidering its initial condemnation as “antiquarian” on its publication becomes a means to rethink collections as heritage resources in relation to Native communities and consider how museum publications are repurposed in other arenas through ethnographic research. This new perspective draws on decades of collaboration with members of the community whose heritage the collection represents, assessing the role of mutually engaged, critical perspectives on “old” museum collections for contemporary museum practice. Using a reflexive lens, I argue that collaborative anthropology recovering historical entanglements and Native voice and agency enables museum resources to engender a post-colonial, post-antiquarian anthropology.
