Founded in 1925, the Hebrew University of Jerusalem has been ranked among the top 100 schools in the world. The Board of Governors has included such prominent Jewish intellectuals as Albert Einstein and Sigmund Freud. The university has produced several Nobel laureates; recent winners associated with Hebrew University include Avram Hershko, David Gross, and Daniel Kahneman. One of the university's major assets is the Jewish National and University Library, which houses over five million books.

Today it is both the central library of the university and the national library of Israel.
