The Jacob Rader Marcus Center of the American Jewish Archives (AJA), located on the historic Cincinnati campus of Hebrew Union College-Jewish Institute of Religion, was established in 1947 by renowned historian, Dr. Jacob Rader Marcus to collect, preserve, and make available for research, materials on the history of Jews and Jewish communities in the Western Hemisphere, including data of a political, economic, social, cultural, and religious nature.
Since the founding of JCRC, its leadership has worked with AJA to preserve thousands of rich historical JCRC documents and materials. The collection consists of correspondence, reports, news releases, clippings, photographs, and other materials relating to the activities of the JCRC from 1934-2007. The largest sections of the collection include materials on antisemitism and the radical right, religion, church and state issues, religion in the public schools, civil rights, Israel, the National Community Relations Advisory Council, and Soviet Jewry. There are also materials on Nazism and the Holocaust, and correspondence with Jewish and non-Jewish organizations, both national and local. Included are records of the JCRC's involvement in, and reaction to, national and local issues and events. The collection also includes financial and administrative records of the Cincinnati JCRC.
