The collection is arranged in four series: GENERAL FILE, COMMITTEE EVENTS, FELLOWSHIP FOR SOCIAL JUSTICE and DAVID SEIDMAN. A majority of the collection was donated by David Seidman, including his correspondence, the Drama Workshop notes (1954-1955), (he functioned as their publicity director), a scrapbook of the Fifth Annual Festival of Arts (May 1956), the Writers' file (1954-1955) and much of the material for the Fellowship for Social Justice file.

The First Unitarian Church of Los Angeles is located at 2936 W. 8th Street, Los Angeles, California 90005.
