The potential of the videodisc has been recognised at the Louvre and space has been set aside in the Richelieu wing, recently made available to the Museum, to accommodate videodisc installations. Three videodiscs have been or are being produced in the first instance. One provides a general approach to the collections in the Louvre; a second assists the visitor to explore aspects of Ancient Greece by means of a choice of itineraries; and the third illustrates the themes of the guided tours of the Louvre and will be used by the guides to provide a brief introduction at the beginning of their tours. Of these only the first is available for sale, the other two having been designed explicitly for use within the Museum.
