In May 2003, an archival database went on-line giving free access to Einstein's scientific and non-scientific documents, correspondences, etc. thanks to the Jewish National & University Library, the Hebrew University of Jerusalem and Cal Tech. This great resource can be found at http://www.alberteinstein.info/.
