Also, I don't know what state you are interested in, but as an example, see
"Tribal-State Relations in South Dakota." by Thomas Shortbull. You can get a
copy of that by writing Oglala Lakota College, Kyle, S.D.
"Reservation Street Law" by Frank Pommerscheim and Anita Remerowski, 1979
is published by Sinte Gleska College Press, Rosebud, S.D.57570. They carry
it in the bookstore.
Good luck,
Paula
