The current "digital revolution" or "digital era" has affected most of the realms of today's world, particularly the domains of communication and the creation, safeguarding and transmission of knowledge. Museums, whose mission is to be open to the public and to acquire, conserve, research, communicate and exhibit the heritage of humanity, are thus directly concerned by this revolution. This collection highlights the manner in which museums and curators tackle the challenges of digital technology. The contributions are divided into four groups that illustrate the extent of the impact of digital technologies on museums: namely, exhibitions devoted to new media or mounted with the use of new media; the hidden face of the museum and the conservation of digital works of art; cultural mediation and the communication and promotion of museums using digital tools; and the legal aspects of the digitalisation of content, whether for creative purposes or preservation.
