This series contains publications of the Walla Walla Kiwanis Club, beginning with a bi-monthly bulletin known as the "K’ Builder" from 1975 to 1989, then as "K-Lines" from 1989 to 1990. In 1992 the club’s monthly newsletter was called "Oikos" (A Greek word meaning “to build”). These one-to-two-page publications informed members of subjects such as club activities, elections, new members, and upcoming events.
