This book explores how digital culture is transforming museums in the 21st century. Offering a corpus of new evidence, the authors trace the digital evolution of the museum and their audiences, now fully immersed in digital life, from the Internet to home and work. As life in code and digits has redefined human information behavior and dominates daily activity and communication, ubiquitous use of digital tools and technology is radically changing the social contexts and purposes of museum exhibitions and collections, museum professionals, and the expectations of visitors, real and virtual. Moving beyond their walls, with local and global communities, museums are evolving into highly dynamic, socially aware, relevant institutions as their connections to the global digital ecosystem are strengthened. As they adopt a visitor-centered model and design visitor experiences, their priorities shift to engage audiences, convey digital collections, and tell stories through exhibitions. This is all part of crafting a dynamic and innovative museum identity of the future, seamlessly integrated with digital culture, digital thinking, aesthetics, seeing and hearing, where visitors are welcomed participants. International and interdisciplinary contributors include digital artists, academics, and museum professionals. Chapters present varied evidence-based research and case studies on museum theory, philosophy, collections, exhibitions, libraries, digital art and digital future, to bring new insights and perspectives and inspire readers. The book demonstrates how digital culture is transforming museums in the 21st century; provides a detailed picture of the museum world with emphasis on museums leading change; offers diverse perspectives on the 21st century museum, from inside and beyond museum walls, of artists, academics, and professionals; and focuses on digital culture and art, digital behavior, the interaction of real and virtual life, and the impact on museums.
