Materials related to the United Brotherhood of Carpenters and Joiners of America (UBCJA) at the national, California and local levels, including convention proceedings, bylaws, agreements, and pamphlets, collected in the course of Johnson's work as business agent for UBCJA's Local 550 Chapter in Oakland, California. While the majority of the collection reflects official documentation from UBCJA and California State Council of Carpenters, also present are publications from workers and players within the Millmen and Carpenter industry. Some materials reflect Johnson's long standing conflict with the National UBCJA organization.
