The wealthy Egyptian Jacques Mosseri financed excavations in thevicinity of the Ben Ezra Synagogue and in the Basatin Cemetery at theend of the nineteenth century and the beginning of the twentieth. Hiscollection remained with the Mosseri family and was unavailable forscholars for many years. In 1970, scholars from the National Library ofIsrael were allowed to microfilm the collection, which resulted in the1990 catalog. In 2006, the Mosseri family loaned its collection toCambridge University for a twenty-year period during which thecollection would be conserved, digitized, and studied and then,conditions permitting, deposited in the National Library of Israel. ForMosseri’s account of how he obtained his collection, see his “A NewHoard of Jewish MSS in Cairo,” Jewish Review 4 (1913): 208–16. Formore information on the subsequent history of the collection, see theintroduction to the 1990 catalog; and http://www.lib.cam.ac.uk/Taylor-Schechter/jmgc.
