"The Albert Einstein Archives" is a subdivision of the Jewish National & University Library, and is jointly developed and maintained with the Hebrew University of Jerusalem (which holds the copyright of all of Einstein's writings in accordance with Albert Einstein's Last Will and Testament of 1950). The Archives counts about 50,000 items of which a quarter is a scientific material. They contain the largest collection of original manuscripts by Einstein in the world, his correspondence with the most influential physicists and intellectuals of the 20th century, and the “most exhaustive compilation of material about Albert Einstein". The website includes other categories such as Resources on Einstein, Einstein for Kids, News, information about the Literary Estate, as well as one of the most detailed biography and a remarkable timeline for the different phases of his life.

This service provided by The California Institute of Technology, allows browsing of more than 90 annotated photos of Einstein in different phases and on various occasions. PhotoNet is an active part of the Institute Archives that serve as the collective memory of Caltech by preserving the papers, documents, artifacts and pictorial materials that tell the school's history, from 1891 to the present.
 
 
"Einstein Archives Online" is a joint project between Einstein Papers Project at the California Institute of Technology and the Hebrew University of Jerusalem. "This site includes digitized images of Einstein's original manuscripts which have been grouped according to content into three sections: Scientific Writings, Non-Scientific Writings, and Travel Diaries". The site allows viewing and browsing of approx. 3,000 high-quality digitized manuscripts, and enables access to the online version of the Albert Einstein Archives Finding Aid, a comprehensive description of the entire repository. The project has also developed an Archival Database allowing direct access to about 43,000 records of Einstein and Einstein related documents including his professional and personal correspondence, notebooks, travel diaries, personal documents, and third-party items contained in the original collection of Einstein’s personal papers.
