Hi everyone: I'm working with two of our librarians in Special Collections that are interested in finding shapefiles of Indian Reservations for the US from 1900-1990. A few years ago, I digitized reservation boundaries for Arizona from 1880-1990, but we're having a hard time finding the same information for the other states. Does anyone have any ideas about where we could find it? We found reservation boundaries for 1778-1891 but nothing more recent. Thanks Chris Chris Kollen Data Curation Librarian University of Arizona Library P.O. Box 210055 Tucson, AZ 85721-0055 (520) 305-0495 [log in to unmask]
