[The Internet Encyclopedia of Philosophy] Wittgenstein Source - Home. Tractatus Logico-Philosophicus. Tractatus Logico-Philosophicus Side-by-Side-by-Side Edition. Created in part to serve a pedagogical need, I have undertaken a project to create a decently typeset version of Wittgenstein’s Tractatus-Logico-Philosophicus (1922) that presents Wittgenstein’s German original text alongside both major English translations: the Ogden (or Ogden/Ramsey) translation, and the Pears/McGuinness translation. Right now four versions are available in three file formats. All contain Russell’s introduction, and a hyperlinked English index. (The index is taken from the Pears and McGuinness edition). They were created by cleaning up and checking versions of the text found elsewhere on Public Domain sites online to create LATEX source which was then converted to other formats.
I believe these are substantally more correct than most other versions available on the internet, some of which are rife with errors. Stanford Encyclopedia of Philosophy.
