The 9 ledgers of minutes cover 1917 to 1920 and 1941 to 1949. The ledgers include membership minutes, Executive Board minutes and Joint Executive Committee minutes (with members of Lodges 284 and 68). The minutes provide information about members, officers, committees, finances, strikes (including information about strike pay for female employees), social events (including dances), and activities of other unions. Historical events of the time are reflected in the minutes, most notably World Wars I and II and anti-communist investigations of the 1940s.
