These materials were compiled by various anthropologists: Edward Sapir, Franz Boas, Alex Thomas, and Frank Williams. Sapir (ca. 1920) collected and annotated a series of Nootka ethnographic and legendary texts (600 pages of materials), initially intended as a third volume of Sapir and Swadesh, Nootka Texts (1939). Boas (ca. 1900-1913) contributed Nootka vocabularies and grammatical notes (100 slips and 100 pages). Thomas obtained Nootka texts for the collection (ca. 1910-1920).
