from individuals and universities, the National Science Foundation, and the National Endowment for the Humanities. In late 2014, the EPP and PUP launched The Digital Einstein Papers. The website presents the complete contents of The Collected Papers of Albert Einstein, Volumes 1-15. The project volumes are reproduced online as fully searchable PDFs. All documents and endnotes are linked to provide seamless transitions between the original language documentary edition and English translations. Subsequent volumes will be added to the website approximately eighteen months after their release in print. It is projected that there will be thirty volumes in the series. Eventually, the Digital Einstein Papers website will provide access to all of Einstein's writings and correspondence accompanied by scholarly annotation and apparatus. The Early Years: 1879-1902 is the first volume in the series. The Swiss Years: 1900-1914 and The Berlin Years: 1914-1929 followed through volume 16 in two parallel and extensively cross-referenced branches: Writings: published and previously unpublished articles, lecture notes, research notes, accounts of his lectures, speeches, interviews, book reviews, etc. Correspondence: letters, travel diaries, calendars, documents about Einstein by third parties, etc. The early years: 1879-1902 Volume 1 - Collected Papers 1879-1902 Includes many previously unpublished documents, e.g. class notes for Heinrich Friedrich Weber's lectures on thermodynamics and electromagnetism during Einstein's second year at ETH Zurich, etc. The Collected Papers of Albert Einstein, Volume 1, The Early Years: 1879-1902.
