From site: The Einstein Archives Online Website provides the first online access to Albert Einsteins scientific and non-scientific manuscripts held by the Albert Einstein Archives at the Hebrew University of Jerusalem and to an extensive Archival Database, constituting the material record of one of the most influential intellects in the modern era.
The site allows viewing and browsing of approx. 3,000 high-quality digitized images of Einsteins writings, available for viewing in two sizes: a standard resolution image, as well as a high-resolution image for closer inspection. This digitization of more than 900 documents written by Einstein was produced by the Jewish National & University Librarys Digitization Project and was made possible by generous grants of David and Fela Shapell.
