Records
Agencies and subagencies were created as administrative offices of the Bureau of Indian Affairs and its predecessors. Their purpose was (and is) to manage Indian affairs with the tribes, to enforce policies, and to assist in maintaining the peace. The names and location of these agencies may have changed, but their purpose remained basically the same. Many of the records of genealogical value (for the tribe and tribal members) were created by these offices.

Letters received by the Office of Indian Affairs from the Blackfeet Agency, 1873-1876, have been microfilmed by the National Archives as part of their Microcopy Number M234, Roll 235. Copies are available at the National Archives and at the Family History Library and its family history centers (their ).
