The opening as it read in 2005

Cairo Geniza is an accumulation of Jewish manuscripts written from about 870 to as late as 1880 CE, that were found in the geniza of the synagogue of Fustat (Old Cairo), Egypt (built 882), the Busatin cemetery east of Old Cairo, and a number of old documents that were bought in Cairo in the later 19th century that are now archived in various American and European libraries. The Taylor-Schechter collection in the University of Cambridge runs to 140,000 manuscripts; there are a further 40,000 fragments at the Jewish Theological Seminary of America. The importance of these materials for reconstructing the social and economic history for the period between 950 and 1250 cannot be overemphasized; the index the scholar G.D. Goitein created covers about 35,000 individuals, which included about 350 "prominent people" (which include Maimonides and his son Abraham), 200 "better known families", and mentions of 450 professions and 450 goods. He identified material from Egypt , Palestine , Lebanon , Syria (but not Damascus or Aleppo), Tunisia , Sicily , and even covering trade with India . Cities mentioned range from Samarkand in Central Asia to Seville and Sijilmasa , Morocco to the west; from Aden north to Constantinople ; Europe not only is represented by the Mediterranean port cities of Narbonne , Marseilles , Genoa and Venice , but even Kiev and Rouen are occasionally mentioned. As proof that their creators were integrated in their contemporary society (and not isolated in a ghetto like later European Jews), many of these documents were written in Arabic in Hebrew characters. As evidence for how colloquial Arabic of this period was spoken and understood alone, these documents are invaluable. Goitein demonstrates that they were part of their contemporary society time and again: they practiced the same trades as their Muslim and Christian neighbors, including farming; they bought from and sold to, and rented from and rented to their contemporaries. The light this material casts on the period of the Fatimid and Ayyubid rulers extends beyond the world of their authors. These materials include a vast number of books, most of them fragments, which Goitein estimated to number 250,000 leaves; these include parts of Jewish religious writings, as well as fragments from the Qur'an . The non-literary materials, which include court documents, legal writings and the correspondence of the local Jewish community, are somewhat smaller, but still impressive: Goitein estimated their size at "about 10,000 items of some length, of which 7,000 are self-contained units large enough to be regarded as documents of historical value. Only half of these are preserved more or less completely." To put this in prespective, Jacob Lassner furnished the estimate that all of the Arabic papyri and other writing found in Egypt number less than 100,000.1
