The present text, which is the result of research effectuated in the framework of the University of Nanterre, obviously does not constitute an exhaustive study of the Situationist International. I have only had the ambition to open a new field of interrogations of the revolutionary movement of May 1968. Since this subject has been approached very infrequently in the last twenty years, I believe that one will at least recognize in me the merit of beginning to renew it.
I thank all those whose help and support have allowed me to complete this research. And particularly the International Institute of Social History in Amsterdam and the Library of International Contemporary Documentation in Nanterre, where I consulted very rich archives.The Author
