[3] The library of the Jewish Theological Seminary was founded in 1893 through donations from private individuals including Cyrus Adler, Mortimer L. Schiff, Felix M. Warburg, Louis Marshall, Mayer Sulzberger, and Elkan Nathan Adler.
[5] On April 18, 1966, the library caught fire, destroying some 70,000 volumes, including forty Torahs.
[8] One of its rarer possessions—a pinkas, or journal, which belonged to a rabbi from Tiberias who had toured Europe around the early 19th century—was discovered at an auction in 2021, raising concerns around the "lack of transparency around the sale of the manuscript" among Judaica librarians and consultants.
[9] The Jewish Theological Seminary Library holds over 11,000 Hebrew manuscripts, making it the largest such collection in the world.
Additionally, it has 43,000 fragments from the Cairo Geniza, over 500 ketubahs, and 4,000 rare and significant broadsides published from the 16th to 20th centuries.
