No Book Is Perfect (But...) 

Einaudi is the main publisher of Wittgenstein's works in Italy. Their editions are excellent and usually they are well printed, too.
The Ludwig Wittgenstein Project (www.wittgenste...) is a website whose aim is to make available as many of Wittgenstein's works as possible, free of charge and with a free license.
On 1 January 2022, Wittgenstein's works will enter the public domain almost everywhere in the world. Starting from that date, The Ludwig Wittgenstein Project will provide complete, well-formatted, downloadable, free books: the German or English originals will be available, as well as translations in multiple languages that were purpose-made by our team.
