This catalogue presents the Islamic, Oriental Christian, Judaic and Samaritan manuscripts in the University library of Leipzig’s collection. The largest part of the material is Islamic, and it is presented here according to categories. Manuscripts are described by title (if known) and a brief summary of the contents. Dimensions for most of the pieces are given as well. The Christian material includes manuscripts in Arabic, Syriac, Coptic, Ethiopic, and Georgian. A numerical concordance adds to the utility of this important manuscript collection.
