The Wiener holds more than 1,600 catalogued document collections, and we recive about 50 new collections each year. Some of the most extensively used have been digitised and made publicly available. These include the Library's Special Collections, which contain anti-Semitic, anti-Nazi and anti-Communist propaganda, ephemera, documents on POWs, various currencies and artefacts, and political leaflets. The Library’s own institutional archives remain a key resource for researchers, especially the Jewish Central Information Office reports from the early 1930s and the Library’s pre-1963 correspondence. Other important collections include Nuremberg War Crimes Trial documents donated by the trial authorities as quid pro quo for services provided by the Wiener.

The Library also hold hundreds of personal and family papers. These include the Altstadt family collection, which give a detailed insight into Jewish life in different parts of the Austro-Hungarian Monarchy before the First World War, and Gordon family papers, which include one of our most detailed sets of personal correspondence.

Our photo collections encompass an estimated 40,000 items, around half of which are linked to document collections, the other half constituting standalone photo collections. We hold photos of concentration camps and ghettos, the Kindertransports, and post-war Displaced Persons and Jewish relief efforts. Of note is the Mendel Grossmann collection, documenting facilities established and run by the Jewish Council of the Litzmannstadt Ghetto.
