The 7,000 Mosseri manuscripts are derived from the classical Genizah period (10–13th centuries CE) and from later periods right up to the nineteenth century. The fragments include Bible, rabbinica, liturgy, medicine, documents, belle-lettres, and documentary papers of interest to historians of the modern period of Egyptian Jewry.
Cambridge University Library was given the hitherto unseen Jacques Mosseri Collection in 2006 as part of a long-term loan agreement with the Mosseri family. During this period, the Mosseri manuscripts will be conserved, digitised and described, and the resulting catalogue will be freely accessible on the internet.
