Acción Latina, a largely volunteer-run community organization based in San Francisco’s Mission District, has been publishing a twice-monthly, bilingual newspaper since 1970 and producing an annual festival celebrating Latin American music since 1982. In 2017, the Bancroft Library at the University of California, Berkeley acquired the Acción Latina pictorial archive. For my capstone, I processed and arranged the nearly 10,000 photographic prints and over 600 posters in the archive, and wrote a detailed, searchable finding aid that is now published on the Online Archive of California.
