International audience; The reflections in this chapter stem from the perspective of the DARIAH-ERIC,a distributed infrastructure for the arts and humanities. They explore how impactcan take a variety of forms not always considered when the term is applied in astrictly technocratic sense, and the idea that focussing on the user of a research infrastructuremay not describe an optimal relationship from an impact perspective.The chapter concludes by presenting three frames of reference in which an infrastructurelike DARIAH can have impact: to foster excellence through impact on researchers,promote fluidity through impact on policymakers, and support efficiencythrough impact on our partner organisations.
