Over the years the Navajo language has received more attention than any other American Indian language. The grammatical work represents all traditions in American Indian linguistic research, from the earliest descriptivism to the latest generative grammar. In addition, there exists a large amount of material written in Navajo and a plethora of pedagogically oriented research. With a population of more than 130,000, Navajo has the best chance of survival of any Indian language north of Mexico. Most important, recent years have witnessed the development of a dynamic and professional Navajo bilingual education movement. The involvement of increasing numbers of Navajos in linguistics and language education makes this a field of special theoretical and practical relevance. A preliminary attempt to cover the field of Navajo language research, this bibliography cites 478 references that relate to the study of the Navajo language. Published between 1829 and 1973, these references cover grammatical research; dictionaries; vocabularies; taxonomies; texts; comparative Athapaskan research that includes significant Navajo work; language, culture, and sociolinguistic research; and language pedagogy studies. Also listed are historical and anthropological studies that contain some Navajo language forms. (Author/NQ)
