This article examines the recently proposed ICOM museum definition and its detractors in order to trace the history of museums and their social purpose as they move from a traditional past into a tumultuous present and uncertain future. As countries begin to reframe the role of arts and culture in shaping a world affected by a global pandemic, museums will need to address not only practical measures – such as social distancing guidelines and limited visitor numbers – but also how these institutions are situated within the greater social context. Technology is particularly useful for museums to share their collections with audiences and transcend geographical boundaries, and it also allows these institutions to reposition themselves as relevant within the ongoing cultural heritage dialogue and context. However, it is debatable whether online and digital offerings classify as museums. Even if there is no consensus on the textbook definition of museum, pinpointing common traits will help establish their evolution and role for current and future generations. Embracing digitization, virtual museums, and other non-traditional frameworks allows for a more expansive and inclusive conception of museums, taking into account their dual role: as custodians of public knowledge and spaces for education and development.
