Le droit du num\'erique : une histoire \`a pr\'eserver

Although the history of informatics is recent, this field poses unusual problems with respect to its preservation. These problems are amplified by legal issues, digital law being in itself a subject matter whose history is also worth presenting in a computer science museum. The purpose of this paper is to present a quick overview of the evolution of law regarding digital matters, from an historical perspective as well as with respect to the preservation and presentation of the works.
