ABSTRACT
The primary sources for studies of peace organizations and campaigns are the materials produced by the campaigners themselves: leaflets, pamphlets, and peace periodicals. Archives are available for some peace organizations, though not all have been preserved. Other internal sources are memoirs of individual activists and leaders of peace campaigns, and histories of particular peace organizations written by members or sympathizers. Liberal or left-wing newspapers and periodicals in some countries have provided sympathetic coverage of the major campaigns.
