• English - With more than 2,000 titles, this is the greatest single source for tracing suffragism and feminism in the English-speaking world. Included are Carrie Chapman Catt's Ought Women to Have Votes for Members of Parliament? (1879), as well as Anti-Suffrage Essays by Massachusetts Women (1916).
• German - These 929 titles document the history of an organized movement, as well as women and socialism, Jewish women's status, and Swiss feminism.
• French - the 734 French titles cover women in the military, law, and reforms in women's legal, civil, and economic rights, as well as women's influence on French literature from Gallic times through World War II.
• Other languages - 12 languages and 472 titles.

Periodical Series Periodicals constitute 25 percent of the entire collection. For the years from 1860 through 1900, the period covered by most of the titles, there is no comparable resource. Gerritsen scrupulously sought complete runs, and her successors acquired additional materials to fill whatever gaps arose. The result is a collection of 265 titles, among them The Suffragist (1913-21) and The Women's Protest Against Woman Suffrage (1912-18).
