Jewish Historical Institute (Warsaw, Poland)
From the website: "The Jewish Historical Institute focuses entirely on the study of the history and culture of Polish Jews. It is the largest depository of Jewish-related archival documents, books, journals, and art objects. The preservation of collections that document ten centuries of Jewish experience in Poland allows for research and education to be carried on. We believe that education makes people aware of the history that Poles and Jews shared and helps to overcome stereotypes."

From the website: "Foundation for the Preservation of Jewish Heritage in Poland was established by the Union of Jewish Communities in Poland and the World Jewish Restitution Organization (WJRO). Our mission is to protect and commemorate the surviving monuments of Jewish cultural heritage in Poland. The Foundation is active in regions whose location far from major cities makes it difficult for Jewish communities to provide adequate care. Our area of operation covers nearly two thirds of Poland."
