The bulk of the collection, and its greatest strength, consists of correspondence from Margaret Sanger, circa 1916-1955. There are also photographs and portraits of Juliet Rublee; pamphlets and articles on birth control and other topics; and a Master's thesis, examining the correspondence between Juliet Rublee and Margaret Sanger, by Jane Bowers (1994). A collection of glass slides, used for protesting World War I may be of interest to scholars of pacifism.

Note: The Sanger correspondence was indexed and microfilmed for the Margaret Sanger Papers Project in 1996.
