The Josephine Butler Society Library is an unrivalled resource for the study of sexuality and public morality from the late nineteenth to the mid twentieth century. This unique collection of books, pamphlets, periodicals, leaflets and, campaigning documents, covers subjects ranging from the regulation of prostitution, venereal disease, social purity, sexuality and public health to criminology, penology, eugenics and population control. Although a small number of individual items continue to be added to the collection by the Josephine Butler Society, the bulk of the printed materials date from the late nineteenth and early to mid twentieth centuries.

The Josephine Butler Society Library is particularly important because it brings together the Library of the organisation alongside its campaigning literature and business papers. In addition to sources for the study of prostitution and attitudes to sexuality in Britain the collection includes significant amounts of material on slavery, procuring, public health and the armed forces in India. It contains late nineteenth century works on sexology by Havelock Ellis, Bloch, Forel and Krafft-Ebing and psychology by Freud, Jung and Ellis, as well as works on marriage, the family and sex education. Although most material in the collection is in English there are small but significant numbers of works in European languages. The geographic scope of the collection extends beyond Britain and the Commonwealth; papers of the International Bureau for the Suppression of Traffic in Persons 1899-1968, for example, relate to the Bureau's work with the League of Nations.
