By the end of 2015, new facsimiles of most of the Nachlass from the Wren Library at Trinity College will be online at the Wittgenstein Archives at the University of Bergen, including: Wittgenstein: Lectures, Cambridge 1930-1933, From the Notes of G. E Moore Cambridge: Cambridge University Press (2016).

"We are happy to announce that a significant part of the new high quality Wittgenstein Nachlass facsimile edition is already online. This includes such prominent items as the Big Typescript, the Brown Book and the Lecture on Ethics. The Wittgenstein Archives at the University of Bergen (WAB), in co-operation with Trinity College Cambridge and the Stanhill Foundation, is producing a new Nachlass facsimile of Wittgenstein originals, which are freely available online on WAB's Wittgenstein Source site.  By the end of 2015, new facsimiles of most of the Nachlass from the Wren Library at Trinity College will be on the site, as well as facsimiles of the Nachlass from the Austrian National Library in Vienna. Plans for future additions include Nachlass facsimiles from the Bodleian Library in Oxford as well  as the Russell Archives in Ontario. In addition to the facsimile edition, Wittgenstein Source will also host updated text editions and archival and text-genetic descriptions of the single Nachlass items.

Wittgenstein Source also hosts its first Wittgenstein primary source that is not part of the Wittgenstein Nachlass in the strict sense of the term: facsimiles of six of G.E. Moore's notebooks, containing his almost verbatim record of Wittgenstein's classes, Cambridge, 1930-1933. Also included are facsimiles of Moore’s later summaries of his lecture notes, and a 1932 essay by Moore critiquing Wittgenstein's conception of grammar. This edition is provided by David G. Stern, Brian Rogers, and Gabriel Citron. The facsimiles are reproduced by kind permission of the Syndics of Cambridge University Library, Perry Moore, and Thomas Baldwin. They were purchased thanks to a Franklin Research Grant from the American Philosophical Society and a grant from the University of Iowa Arts & Humanities Initiative. The three editors have also produced a book edition of these materials: Wittgenstein: Lectures, Cambridge 1930-1933, From the Notes of G. E Moore Cambridge: Cambridge University Press (2016)."
