This article examines the role of primary ethnographic materials - of field notes, letters and photographs - and even of the shelves and bookcases - in building accounts of the human condition. We trace the lives of incomplete and not-yet-found manuscripts, which have been treated as representative of whole archives, as well as closely held convictions and ideas in the history of anthropology. In so doing, we employ the notion of a 'proxy', or a set of signs and images which point the audience in particular directions, without determining their overall destination. Our research is based on a few episodes from the histories of paper and digital copies of manuscripts and photographs of the anthropological couple Sergei and Elizabeth Shirokogoroff, who conducted ethnographic, linguistic and some archaeological research, first on the borderlands between China and Russia, and then later within China. We aim to show the complexity and social and intellectual vibrancy of their ethnographic field archives, which have been scattered across countries, institutions and personal collections. We conclude by suggesting that engaging anthropologically with field archives enables us to approach existing perspectives on archives in a new way, viewing them not as containers of catalogued information, but as entanglements reflecting social relations in local communities, the trajectories of ethnographers, and the aspirations of scholars asking questions today.
