The Dr. Steven Ungerleider Collection of Haggadot, the text recited on the first two nights of the Jewish Passover, is remarkable for its geographic, linguistic, and temporal diversity. The collection comprises haggadot from Asia, Africa, Europe, North America and the Near East. It incorporates a wide range of Jewish vernacular languages, from Yiddish and Ladino to Judeo-Italian and Judeo-Arabic in representative exemplars from Jewish communities across the globe, many long since dispersed. The collection covers more than four hundred years of Jewish culture, from the Ottoman Empire in 1505 to the State of Israel in the 1950s.
