The Northwest Tribal Oral History interviews contains information pertaining to a wide variety of Native American tribes and peoples in Washington State.  The interviews reflect perspectives of individual tribe members as well as elders. The majority of these interviews are conducted with both members and elders of the Lummi and the Nooksack tribes. Other interviewees include members and elders from the Chinook, Chehalis, Cowlitz, Pachenant, Quinault, Colville, Sinkiuse, and Swinomish tribes. Although the majority of interviews deal with Washington tribes, there is also an interviewee who speaks about her father who was half Nez Perce, an Idaho tribe. Another audio tape records Nez Perce songs. Some topics discussed in these interviews and recordings include Native American languages and word etymologies, religion, education, genealogy, songs, hunting and fishing as well as politics. Also contained within the collection are recordings of the Northwest Indians Executive Council meetings and conferences held in Spokane, WA in 1973.

Although the material in Northwest Tribal Oral History interviews span from 1963-1973, the majority of it dates from 1973. Eighteen interviews out of the fifty four audio tapes have transcriptions. Due to the age of the audio cassette recordings, some tapes are completely inaudible.
