What uses for which pasts? Which pasts for what uses? These questions are political, cultural, social, epistemological, and technical in nature. They tie into the major contemporary challenges surrounding mediation in the digital age, both for scholarly and social uses. The Cluster is interested in intertwined temporalities, contrasted historical and commemorative narratives and their effects, transformations and migrations of representations, materiality of the past and its vestiges, immateriality of know-how and knowing-how-to-be, the dematerialized circulation of collections. Pasts in the Present seeks to tease out the linkages between history, heritage, and memory.
