The significance of the Catalog of the Escorial Library lies in the fame and importance of its contents of Arabic manuscripts, though what was published does not exceed a small number from the Escorial collections. Some of the reviewed Arabic manuscripts are exceptionally rare, since they are the only surviving copies all over the world, such as the autograph of Libāb al-Muhsal written by the eminent savant Ibn Khaldūn in 752 H. in Maghribi handwriting.

Number of pages: 858.
