A World-Class Collection

The JTS Library’s Special Collections are world-class. With the largest collection of Hebrew manuscripts on earth, the most complete collection of early Hebrew printed books (incunables), 43,000 fragments from the Cairo Genizah, and much more, there are few collections that offer students, scholars, and visitors material of such quality, depth, and breadth. Our outstanding rare collections include:

  • Hebrew Manuscripts: With 11,000 Hebrew manuscripts, JTS has the largest such collection in the world. Among outstanding sub-collections are those in rabbinics (over 2,500), Bible, Jewish philosophy and poetry, liturgy, and philology. Images of many manuscripts, including those digitized by the Polonsky Digitization Project, are available through our Makor online discovery tool.
  • Genizah Fragments: From the Ben Ezra Synagogue in Cairo, representing Jewish life in the eastern Mediterranean world and beyond from the 10th to the 19th centuries. Outstanding examples include a letter signed by Maimonides and a handwritten letter by the great Hebrew philosopher and poet Judah Halevi. Genizah fragments may be viewed online or, during our 21st Century Campus Project, in the Rare Books and Special Collections Department at the Firestone Library of Princeton University.
  • Incunables: Hebrew books printed from the birth of movable-type print through 1500, illustrating the interests and commitment of Jews in the 15th century.
  • Ketubbot: Over 500 Jewish marriage contracts, providing evidence of Jewish art and culture from the 17th through the 20th centuries. Digitized images are available through Makor.
  • Broadsides: 4,000 rare and significant pieces spanning the 16th to the 20th centuries from communities in Europe, Israel, the Near East, and America. Broadsides are sheets printed on one side, including posters, handbills, or signs. The collection includes poems and prayers, Kabbalistic writings, genealogical charts, micrographs, maps, and legal documents. Some are available online; please consult a librarian.
  • Scrolls: 430 scrolls, including Torah and Haftarah scrolls, Kabbalistic scrolls, and 300 Esther scrolls, some of them decorated.
  • Archives: Our archival collections include papers representing the history of Jews in the United States, and the Conservative Movement in particular, during the 20th century. We also hold significant Jewish music archives. Finding aids for specific archives are available through Makor.

Polonsky Digitization Lab

The Library has an active digitization program, providing online access to thousands of digital images, many of them one-of-a-kind manuscripts, with more being added every day. Most of these images were created in the Library’s Polonsky Digitization Lab in Memory of Rabbi Marc H. Tanenbaum, which was dedicated in 2015, and many were the product of the Dr. Georgette Bennett and Dr. Leonard Polonsky Digitization Project.

The Library’s Conservation Department is responsible for the protection, stabilization, and repair of rare materials for in-house exhibitions as well as loans to other institutions. It is the care and expertise of our conservators that make possible our aggressive loan and digitization programs. Without their extraordinary skills, it would be impossible for us to protect our rare materials while providing wide access to these treasures.

Our Conservation Department will reopen in our new Library.
