Abstract
International audience WEB 2.0AND MUSEUMS: THE NEW EACES OF THE VISITOR The increasing integration of techniques from Web 2.0 by the museums illustrates the profound changes that these structures have realized in building their relationship with the audience. The use of these devices, based on a logic of participation, leads to involve the visitor, traditionally rather kept at a distance, on all stages of the implemeritation of the mUseum offered on Internet. Through a careful examinât icin of sites arid features offered by the museal structures, different roles now devolved to the public have been identified. The emergence of these new "faces" of the visitor comes to question, in the longer-term, about the identity and the legitimacy of the museums themselves.
