Over at Princeton University Press:

The Digital Einstein Papers is an exciting new free, open-access website that puts The Collected Papers of

Albert Einstein online for the very first time, bringing the writings of the twentieth century’s most influential scientist to a wider audience than ever before. This unique, authoritative resource provides full public access to the complete transcribed, annotated, and translated contents of each print volume of The Collected Papers. The volumes are published by Princeton University Press, sponsored by the Hebrew University of Jerusalem, and supported by the California Institute of Technology. The Digital Einstein Papers—einsteinpapers.press.princeton.edu—launched in December 2014 with the contents of Volumes 1–13 of The Collected Papers, covering the first forty-four years of Einstein’s life, up to and including the award of the Nobel prize in physics and his long voyage to the Far East. The contents of each new volume will be added to the website approximately eighteen months after print publication. Eventually, the website will provide access to all of Einstein’s writings and correspondence accompanied by scholarly annotation and apparatus, which are expected to fill thirty volumes.

The Digital Einstein Papers features advanced search technology and allows users to easily navigate between the original languages in which the texts were written and their English translation, as well as extensive explanatory footnotes and introductory essays. The website also contains links to the Einstein Archives Online, where there are thousands of high-quality digital images of Einstein’s writings.
