This bibliography is an outgrowth of a project begun in the summer of 1956 with the support of an Eban F. Comins grant provided by the Department of Anthropology of the University of Arizona. I had just completed my first year of graduate work in the anthropology department and had determined to focus my studies on the Papago Indian (Tohono O=odham) community living on the San Xavier Reservation some nine miles south of downtown Tucson, Arizona.

Since I’m linking to bibliographic references, here is a bibliography for Philip K. Dick, about whom I had posted before.
