Approximately half of the collection consists of programs and other material related to biennial conferences, in particular the 12th Congress held in Istanbul, 1935. Material from this Congress includes committee reports and resolutions, correspondence, programs, publicity, speeches, and memorabilia. Documentation for other congresses is more sparse, consisting mainly of programs. There are also official conference reports (1906-61) and general documents such as agendas, publicity, position papers, newsletters, and printed material. Major topics addressed include women's rights, women's suffrage, the international women's movement, peace, and the United Nations.
