The use of technologies in the context of museums and cultural institutions is a topic that helps bring a focus to the myriad of representational, interactive and informational forms these cultural milieux allow. Combined with developments in the public take-up of mobile technologies and networked media and communications, technologies used in representing and producing culture cause us to fundamentally re-imagine and reinvent the role of cultural institutions in a technological society. This case study source book is a snapshot, a distillation of contemporary practice by museums and cultural institutions, along with commentary, critique and best practice reflections by interdisciplinary-researchers from the MeLa project.
