In 1934 the New York Public Library purchased a sizable collection of 250 volumes of Arabic manuscripts through the fund for Semitic literature that had been provided by Jacob Heinrich Schiff (d. 1920). While the collection is known to have been purchased in Baghdad, no further details are available about the transaction. The collection contains a fair number of writings by Ibr¿h¿m Fä¿¿ b. ¿ibghat All¿h al-¿aydar¿ al-Baghd¿d¿ (d. 1299/1882) and by some earlier members of the prominent ¿usayn¿b¿d¿/¿aydar¿-family, and this in addition to numerous Twelver Sh¿¿¿ titles.The present volume contains a facsimile reproduction of Ms New York Public Library, Volume 51985A, which belongs to the Sh¿¿¿ material among the collection.
