The volume scrutinizes publics and infrastructures not separately but in their constitutive interrelations and resonances. The contributions, originating in a range of disciplinary perspectives, share a praxeological approach, discussing historical and current processes of mediated cooperation in infrastructuring and making public(s) by tracing different forms of the production, design, and historic trajectories of various publics and infrastructures.
