Officially released on the Web last week, this impressive digital archive features the writings, scholarship, and thoughts of Albert Einstein, one of the 20th century's greatest scientists. The site allows visitors to view and browse 3,000 high-quality digitized images of Einstein's writings, ranging from his travel diaries (many of which are in German) to his published and unpublished scholarly manuscripts. The online archive draws on the manuscripts held by the Albert Einstein Archives at the Hebrew University of Jerusalem, and was produced by the Jewish National & University Library's Digitization Project. Additionally, visitors have access to the archive database, which contains 43,000 records of Einstein related documents, such as his notebooks and third-party items. More casual visitors will want to visit the online gallery, which contains a selection of some of the key documents available here, such as his famous article that mentions the equation E=mc2. Overall, this is a thoroughly engaging and informative trove of digitized material on one of the world's most respected scientists.
