During the 1940’s, Ann Nolan Clark, who worked for the Bureau of Indian Affairs (BIA), published a couple of children’s books in Navajo that were translated by Robert W. Young and J.P. Harrington. This was just one of several projects that Young and Harrington collaborated on. For example, Harrington’s writings include “Southern Peripheral Athapaskan Origins, Divisions, and Migrations” and the Navajo portion of “Earliest Navaho and Quechua” (1944), which were coauthored by Robert W. Young.
