JERUSALEM, Israel -- The Hebrew University Jerusalem on Monday launched a new, expanded Albert Einstein Archives website.

The expanded website will offer thousands of documents and digitized images previously unavailable to the public.

Of the 80,000 documents housed at the university's Einstein Archives, more than 40,000 come from the scientist's personal papers.

In his 1950 will, Einstein bequeathed all of his professional and personal writings to Hebrew University.

Over the past two decades, the university has discovered an additional 40,000 documents related to Einstein.

The joint project to update and expand the archives began in early 2011 with the university's Pasadena, Calif.-based partner organization, Einstein Papers Project, which shares a common data base with Hebrew University. Princeton University Press published the Collected Papers of Albert Einstein.

All the material will now be accessible online.
