Talk:Crow Creek Sioux Tribe
Go to the Catalog in familysearch.org. Then go to the keyword search. Type in Bureau of Indian Affairs + Crow Creek (or whatever tribe you are researching) to access the microfilm records that are available through the Family History Library. If you are not local to Salt Lake, you can order copies of the microfilm online and for the cost of postage, they will be mailed to a local FamilySearch Center near your home. You will then be able to read the microfilm there at the Center.
