English version of Quatuor on line since August 1999

All the texts of the site are protected by the French law of the 11th Mars 1957 which forbids copies and reproductions designed to collective use. Whatever the process, any complete or partial reproduction without the consent of the author is illicit and is a pirating punished according to the article 425 and followings of the penal code.

The drawings and diagrams without any reference are by the author. The pictures which are not from the author (drawings, diagrams, photographs) have a clear mention of their author and of their source, what respects the article 41 of the law of the 11th Mars 1957 about the rights of the authors. These pictures are not used to embellish the texts' presentation, but as short quotations justified by the critical, polemical, educational and scientific nature of the text to which they are here incorporated.
