Series is made up of records relating to the creation of a Chinook Jargon dictionary, a Big Book created for the Quileute on Chinook Jargon, and lessons for a Chinook Jargon class at Langara College. Powell documented the use of Chinook Jargon in LaPush during research on the Quileute language. His informants used Chinook Jargon regularly, and he began to research the history of its use on the Northwest Coast with the intention of writing a book about it. The manuscript for his book was accepted by the publishing company Douglas and McIntyre, but as Powell was not satisfied with his work, publication did not take place. However, he did produce a number of works that have been used for education purposes in LaPush as well as in British Columbia.

Series comprises six sub-series:
A. Research materials
B. Field notes and correspondence
C. Unpublished manuscript and lessons
D. Chinook Jargon dictionary files
