The collection includes meeting minutes of the Board of Directors and Consultative Council (1943-1969), correspondence (1940- ), memoranda, literature and releases, financial records, statistics, subject files, newspaper clippings, photographs, motion pictures, and much other material. In addition to the administrative records of the Washington office, the 1940-1947 records include correspondence, reports, and publications of 151 Civilian Public Service camps, together with case files of men assigned to CPS camps and of the men who were reclassified or imprisoned. Additional case files covering the period 1949 to 1973 contain information about men who performed alternative service (1-W classification) and about men who sought help with problems relating to military service and/or classification. All case files about individual CPS men and women are restricted. Series titles were established by the organization and modified in 2006 by Swarthmore College Peace Collection (SCPC) staff.

Material in Part I was refoldered and reboxed by student assistants in 2003-2008. With the exception of Series A, material is still largely in the same order as it was when sent to the Peace Collection by NSBRO/NISBCO staff. For the most part, files in Part II and Part III have not been included in this reprocessing effort; partial finding aids for these Parts are available onsite at the SCPC.
