Applications for membership to the American Dental Association and the Portland Dental Association, 1920-1922, 1936

The “Membership materials” series, which dates from 1908 to1969, is mostly made up of event programs for the Oregon Dental Association’s annual meetings. These programs include schedules of the meetings, presidential addresses, information on social gatherings, and clinics on specific dental techniques. The programs also include advertisements for dentistry- related businesses, such as insurance companies and supply depots. This series includes a membership roster and a selection of membership applications from the 1920s and 1930s.
