Wittgenstein Source provides free access to Wittgenstein primary source editions. This includes facsimiles and text editions of Wittgenstein’s philosophical manuscripts (his “Nachlass”). Wittgenstein Source is developed and run by the Wittgenstein Archives at the University of Bergen (http://wab.uib.no/) in cooperation with net7, Pisa, and the Section for Digital Services at the University of Bergen University Library. Scholars and organizations are welcome to submit their own Wittgenstein primary sources for publication on Wittgenstein Source, for example editions or translations of Wittgenstein's works, correspondence or lectures. The Wittgenstein Source start page and header make use of a photograph taken by Ben Richards of Wittgenstein in Swansea in 1947; the photograph is used with the kind permission of Michael Nedo and the Cambridge Wittgenstein Archive.
As of May 2016, the following editions are available:
