Since the inception of the “computer age,” much talk has been heard about applying this relatively new technology for manipulating information to the medieval manuscript fragments from the Cairo Geniza. The uses of the Geniza, particularly its documentary sources, for Middle Eastern history will be well known to many readers of this Bulletin. The thousands of letters, court records, marriage contracts, lists, and other documentary treasures, preserved for centuries in a large discard chamber in what is today the Ben Ezra Synagogue in Fustat, and written in Hebrew or Judæo-Arabic (Arabic in Hebrew letters), with a small number in Arabic language and script, constitute an unmediated source for the reconstruction of what the late Professor S. D. Goitein called the “Mediterranean Society” of Jews, Muslims, and Christians of the high Middle Ages.
