The edited volume “Ordering and delimiting knowledge – from analogue to digital Europe?” asks how knowledge orders confirm, reinforce, question or create new social differentiations, and to what extent the digital transformation changes such differentiation processes gradually or in principle. Knowledge orders are understood here as intentionally construed and medially mediated orders that delimit, systematise, classify and categorise bodies of knowledge. The contributions to this edit-ed volume examine the emergence, establishment and contestation of such knowledge orders on three levels: their practical social relevance, their European dimension, and their transformation through digital representation.
