Yesterday the Albert Einstein Archives at the Hebrew University and the California Institute of Technology, where the Einstein Papers Project has its
headquarters, started a new Web site, www.alberteinstein.info.
It contains digitized images of some 900 Einstein papers as well as a searchable list of 43,000 documents in the archive. Hundreds more are held by
people or institutions other than the Hebrew University and some within the official archive itself are closed until 2006. The Web site was
inaugurated in connection with a meeting of Einstein scholars yesterday at the American Museum of Natural History in New York.
The online collection includes all 230 original scientific manuscripts and drafts that were in his possession when he died, said Dr. Diana Kormos
Buchwald, a historian of science at the California Institute of Technology and the director of the papers project.
Among them, she said, is a notebook in which he worked out his general theory of relativity, which explained gravity as the warping of space-time
geometry and is generally regarded as his greatest achievement.
I've checked this site and found that almost everything appears to be in German, but for anyone interested the link is below.
