Excerpt from the report: This list of references is a revision of typewritten lists dated June 29, 1932, December 7, 1932, and January 16, 1933. It does not entirely supersede the list of January 16, as a few items chiefly references to international barter and barter in foreign countries have been omitted. It attempts mainly to list references on the present use of barter aid scrip in the United States including its use by chambers of commerce, municipalities and self-help and emergency cooperative exchanges for the relief of unemployment. A few selected references on the history of barter and scrip have been included.
