The Einstein Papers Project was established in 1986 to assemble, preserve, translate, and publish papers selected from the literary estate of Albert Einstein (more than forty thousand documents) and from other collections (more than 15,000 Einstein-related documents).
Sponsored by the Princeton University Press and the Hebrew University of Jerusalem since its inception, the project was located at Boston University until 2000. The project is also supported by endowments from individuals and universities, the National Science Foundation and the National Endowment for the Humanities. The Project is now located in Pasadena, California at the California Institute of Technology, which Einstein first visited in 1930.
In late 2014, the related universities and archives announced the release of documents of Albert Einstein, available online at The Digital Einstein Papers.
In the first two decades of the Einstein Papers Project, the Princeton University Press has published ten of the projected twenty five volumes in the series, The Collected Papers of Albert Einstein.
Introductions, headnotes, footnotes, etc., are provided in English, while all documents in the series are reproduced in the language in which they were originally written. The Press simultaneously publishes English translations of previously untranslated documents when it releases each volume in the series.
Includes many previously unpublished documents, e.g. class notes for Heinrich Friedrich Weber's lectures on thermodynamics and electromagnetism during Einstein's second year at ETH Zurich, etc.
