Microfilm and digital surrogates of microfilm are available. See Volume 1, reel 20. Only original documents created by Harrington, his collaborators and field assistants, or notes given to him were microfilmed.
Electronic inventory available. Consult with archivist.

This subseries of the Alaska/Northwest Coast series consists of notes recorded during Harrington's survey of Northwest Coast languages undertaken, in part, during an extended period from January 1942 through February 1943. Some information regarding Tillamook dates as early as March or April 1942; much rechecking was certainly done in early June, probably around the 7th to the 10th.
The work began at Bay Center, Washington where Harrington located Sammy Jackson (Sammie), whose father was a Tillamook, at Bay Center, Washington. The remainder of the work was centered at Siletz, Oregon where he contacted Clara Pearson (Clara, rarely Cl.), a speaker of the Nehalem dialect; Louie Fuller (Louey, Louis, Lf.) of the Salmon River region; and his wife (Mrs. Lf.). Most of the native words from these speakers are in Tillamook, with occasional equivalences given in Chinook jargon. There are some Clatsop data in the section on placenames. Comparative data from other Oregon residents include Alsea from John Albert (Ja. or Jack) and Lower Umpqua from Frank Drew (Frank) and Spencer Scott (Spencer). Several references are made to Ada Collins, a speaker of the "Rogue River language." There are also a number of "rehearings" of Cowlitz and Chehalis terms from Emma Luscier (Em.) of Bay Center and Lizzie Johnson (Liz.) of Oakville, Washington. Nonlinguistic information was provided by Harry Mitchell, Louie Smith, Larry Hofer, Mark Gray Collson (or Colson), his wife Margaret (Marg.), and his son Mark Collson, Jr.
Drawings of specimens and sketch maps are scattered throughout the vocabulary files. There are also references to maps Harrington examined in the Portland Public Library. In addition, he checked over data in an Oregon Coast Highway pamphlet, an article by Silas B. Smith (1901), and Franz Boas' "Traditions of the Tillamook" (1898). A block of ethnographic notes relating to canoe burial is included with the material culture vocabulary. A small section of comments on Boas' "Notes on the Tillamook" follow the original data. In addition, there are abstracts in English of several myths told by Clara Pearson having to do with the etymology or mythological importance of Tillamook placenames. There are also a few notes on phonetics and a number of paradigms.
