This is the only complete catalogue of the nearly four hundred Sanskrit manuscripts contained in the Rare Book Library at Columbia University. The collection is especially strong in works on mathematics and astronomy, assembled by David Eugene Smith (1860-1944), Professor of Mathematics at Teachers College from 1901 to 1926. In addition to scholarly descriptions of the manuscript and the works they contain, the volume has numerous indices covering the persons, places, titles, and dates associated with the manuscripts.
