Wiener Holocaust Library

The Wiener Holocaust Library () is the world's oldest institution devoted to the study of the Holocaust, its causes and legacies. Founded in 1933 as an information bureau that informed Jewish communities and governments worldwide about the persecution of the Jews under the Nazis, it was transformed into a research institute and public access library after the end of World War II and is situated in Russell Square, London.

In 2017, and following a campaign by Daniel Plesch (director of the Centre for International Studies and Diplomacy at SOAS University of London) and other researchers, directed at the UN, the library published an online and searchable version of the catalogue of the archive of the UN War Crimes Commission. It is also home to the UK's digital copy of the International Tracing Service archive, the physical copy of which is held in the Arolsen Archives – International Center on Nazi Persecution in Bad Arolsen, Germany.
