This book is published to mark the 90th anniversary of the founding of the Library. It contains a selection of just fifty items from our archive. Each one tells a story - often tragic, sometimes heroic - of the struggle for dignity and life itself when confronted by barbarity. It attests not just to the inhumanity of genocide but also to endurance, invention and generosity, and the will to survive, in a time of barely imaginable distress. Like the Library's collections, the book bears witness to the history of Nazi Germany and the Holocaust and other 21st-century genocides such as in Darfur; it describes the history of antisemitism, the experiences of refugees, and Jewish life in Europe before the Hitler dictatorship.
