The Congressional Voting Cards created between 1915 and 1921 document the National Woman’s Party’s (NWP) work for the federal woman suffrage amendment. The NWP’s database of 5”x8” paper cards documents the personal histories of members of Congress, political standings within their constituencies, and their views on suffrage. Information was gleaned through personal interviews with members of Congress conducted by members of the NWP, correspondence, and published biographies of the members of Congress. The cards were frequently reviewed for accuracy and updated as necessary. NWP Congressional Committee members, who studied the cards prior to calling on members of Congress to implore their support for woman suffrage, required the information in order to engage them in a fruitful conversation and encourage their support of the issue of woman’s suffrage.
Cards from this era were retained and used at the beginning of the campaign for the Equal Rights Amendment.
