They have been called the Dead Sea Scrolls of physics. Since 1986, the Princeton University Press and the Hebrew University of Jerusalem, to whom Albert Einstein bequeathed his copyright, have been engaged in a mammoth effort to study some 80,000 documents he left behind.

Starting on Friday, when Digital Einstein is introduced, anyone with an Internet connection will be able to share in the letters, papers, postcards, notebooks and diaries that Einstein left scattered in Princeton and in other archives, attics and shoeboxes around the world when he died in 1955.

The Einstein Papers Project, currently edited by Diana Kormos-Buchwald, a professor of physics and the history of science at the California Institute of Technology, has already published 13 volumes in print out of a projected 30.

The published volumes contain about 5,000 documents that bring Einstein’s story up to 1923, when he turned 44, in ever-thicker, black-jacketed, hard-bound books, dense with essays, footnotes and annotations detailing the political, personal and cultural life of the day. A separate set of white paperback volumes contains English translations. Digitized versions of many of Einstein’s papers and letters have been available on the Einstein Archives of the Hebrew University.
