The papers of Frederick Parkes Weber, 1886-1962, consist of case notes from his Harley Street and German Hospital practices, some very fine annotated clinical photographs, and (the bulk of the collection) a large number of volumes and bundles dealing with a vast array of diseases and medical conditions, usually accreted around an original paper by Parkes Weber himself. He described how these 'small collections and bundles around kernels of my earliest writings on the subject' evolved in a letter to the Librarian, Wellcome Historical Medical Museum, 27 Feb 1958: "I was in the habit of surrounding my own writings with manuscript and printed correspondence, and all kinds of cuttings and small articles bearing on the subject. Many interesting autograph letters and small essays have in this way become buried and practically altogether lost." These had become 'gradually very extensive, and many of them have become dislocated and unmanageable'. On examination they have been found to include reprints and cuttings of articles, case notes, notes and annotations, correspondence, and photographs. There is also material on more general philosophical questions, and relating to his book Aspects of Death and other publications, and a little personalia and correspondence. Diaries apparently received with the papers were returned to Parkes Weber late in 1958 to assist in the preparation of the notes published as Miscellaneous Notes (see PP/FPW/D.11) and seem never to have been returned to the Wellcome Library (Parkes Weber to Dr Poynter, Wellcome Historical Medical Library, 24 Dec 1958 and 11 Feb 1959). This is a collection of major importance for the medical historian.

Parkes Weber had a very active life during a period of unprecedented developments in medicine. He produced well over 1000 articles, and was particularly interested in rare diseases and conditions: conditions with which he is eponymously associated are Rendu-Osler-Weber disease (familial telangiectasis), Weber's diseases (localised epidermolysis bullosa), Weber-Klippel syndrome (haemangiectatic hypertrophy of limbs), Weber-Christian disease (relapsing febrile nodular non-suppurative panniculitis) and Sturge-Weber-Kalischer disease (angioma of brain revealed by radiography). His papers also include much on more common ailments and phenomena, on balneological and climatological treatment, healthy life-style and the promotion of longevity, social medicine, etc. His associates and colleagues included many of the great names in medicine of his day.

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.
