The library holds more than 5 million books and is located on the Givat Ram campus of the Hebrew University of Jerusalem (HUJI). The National Library owns the world's largest collections of Hebraica and Judaica and is the repository of many rare and unique manuscripts, books, and artifacts.

Among the library's special collections are the personal papers of hundreds of outstanding Jewish figures, the National Sound Archives, the Eran Laor Cartographic Collection, The Sidney Edelstein Collection (for the history of science), and numerous other collections of Hebraica and Judaica.

The library also possesses some of Isaac Newton's manuscripts dealing with theological subjects. The collection, donated by the family of the collector Abraham Yahuda, includes many works by Newton about mysticism, analyses of holy books, predictions about the end of days, and the appearance of the ancient Temple in Jerusalem. It also contains maps that Newton sketched about mythical events to assist him in his end of days calculations. The library houses the personal archives of Martin Buber and Gershom Scholem.

Additionally, the library houses the Gershom Scholem Collection for the Research of Kabbalah and Hasidism, including Scholem′s personal library and items added since his death in 1982.
