The text of the most relevant philosophical book of the XX Century is now published in the only way which allow us 'to read it with understanding and pleasure'; that is, following the decimal structure of propositions numbering. Wittgenstein's decimals are, actually, hypertext links, alike those in our Web sites. Now, the physical pages of the book match the logical pages of the text; starting from the home page with the seven cardinal propositions or even by opening the book by chance, the reader will find everywhere clear and simple lines of thought on which she can reflect and of which she can enjoy. The impression of an anxious run from the first until the fivehundredtwentyseventh proposition is replaced by the lucid evidence of the cognitive map established by Wittgenstein himself. As to the 'Supplements' he sent to Russell, they contained those remarks of the Notebooks which he checked as 'good' but did not use in the Tractatus: the list will result precious for scholars.
