The Library of the Jewish Theological Seminary of America houses the largest and most comprehensive collection of Judaica and Hebraica in the Western Hemisphere; since its establishment one hundred years ago, seekers of knowledge throughtout the world have availed themselves of its vast resources. It was not through mere chance, hoever, that this magnificent collection of manuscripts and rare books came into being. Its existence is owed to the efforts of farsighted Seminary presidents, diligent librarians and supportive members of the community. Leaders such as Solomon Schechter, Cyrus Adler, Louis Finkelstein and Gershon D. Cohen understood that without an adequate library no teaching program of higher Jewish learning could proceed. In turn, they attracted edicated librarian-scholars such as Alexander Marx, Nahum Sarna and Menaham Schmelzer, who diligently organized the Library's officail treasures, making them available not only to faculty and students, but to the general public as well. Moreover, the tradition of concerned philanthropy established in the past by Jacob Schiff, Louis Marshall, Felix Warburg and Judge Mayer Sulzberger, is now being carried on by generous friends of the Library. As we stand on the threshold of the Library's second century, its objectives are as clear today as they were one hundredyears ago; to enable men and women to study, teach and observe the tenets of their Faith.
