The alphabetical master cards series serves as an abbreviated, annotated index for the more substantial individual service files of Jewish service personnel who won awards or suffered casualties during the war.
The Bureau maintained correspondence files for permanent staff members including Salo Baron, Edward Burnstein, Louis Dublin, Elisha Friedman, Dr.
The forms provided space for reporting the names of service personnel and the number of men and women from a community serving in the armed forces, as well as the number of casualties, awards, and commissioned officers.
By September 1944, local war records committees assumed responsibility for authenticating information about Jewish service personnel whose names were submitted to them by the national office of the BWR.
BWR staff created individual files for soldiers and sailors who were of likely Jewish descent.
The Bureau of War Records include approximately 85,000 individual service files and 320,000 surrogate index cards collected by the BWR and the Greater New York War Records Committee on behalf of Jewish soldiers and sailors who served in World War II. The individual service files typically provide a soldier's name, age, rank, serial number, service branch, home address, civilian occupation, next of kin, awards and casualties.
The BWR also conducted surveys of Jewish doctors, dentists, farmers and refugees who served in the United States Armed Forces and compiled population studies for cities containing Jewish populations greater than 25,000, among them Trenton, N. These files contain supporting documentation culled from newspapers, telephone conversations, and correspondence exchanged among BWR staff and volunteers, service personnel and their families, and representatives of the United States Armed Forces.
During the interwar years, the JWB - Army-Navy Division worked with federated Jewish philanthropic and cultural centers to deliver services to Jewish soldiers located at military bases throughout the United States and abroad.
As the United States mobilized for defensive military actions during the emergency period of 1939-1941, the JWB created new bureaus and committees to deal with particular aspects of social services for American Jewish servicemen and women.
