The Wiener Library (the “Library”) was founded in 1933 by Alfred Wiener, a Jewish-German researcher and journalist who escaped Germany as the Nazis rose to power. Wiener settled in Amsterdam where he established the Jewish Central Information Office and started collecting documents on the rise of anti-Semitism in his home country and in the rest of Europe. In 1939, Wiener left Amsterdam to London where he moved his archive and kept collecting documents including early eyewitnesses’ accounts. The Library which moved from its earlier location in Marylebone to new premises on Russell Square in 2011 is now one of the most extensive archives on the Holocaust and the Nazi era. With a collection of over one million items (including published and unpublished work, press cuttings, photographs etc.), its mission is to preserve its collections, to help researchers, scholars, the media and the public to access it and to promote a better understanding of the Holocaust. Since 2013, the Library has been the only point of access in the UK to the ITS Archive, the largest collection of documents related to the Holocaust with over 100 million pages of providing information on the fate of over 17 million individuals persecuted by the Nazi regime. The Library runs a vibrant programme of temporary exhibitions and events, the vast majority of which are open and free to the public.
