In 1934 the New York Public Library (NYPL) purchased a sizable collection of 250 volumes of Arabic manuscripts through the fund for Semitic literature that had been provided by Jacob Heinrich Schiff. Ms New York Public Library, Manuscripts and Archives Division, Arabic Manuscripts Collection, Volume 51985A, a facsimile of which is included in the present publication, belongs to the Shīʿī material among the collection. It is a multitext volume of 269 leaves which in its present form comprises seven individual works. It is hoped that the present facsimile edition will enable and encourage scholars to delve into the materials it contains.
