The evaluation of societal impact is at the top of the policymakers' and, consequently, university administrators' agendas. Discussions of societal impact are often framed within the language of "accountability". Put simply, the universities at large, and the individual researchers within them, need to prove that they are worth the monetary value they receive. There is, however, far less clarity around the role of universities and research within societies and even less around how to measure such "worth" or "value".The authors of the country chapters presented in this volume have worked together for more than five years in the frame of the COST Action CA-15137 "European Network for Research Evaluation in the Social Sciences and Humanities" (ENRESSH), exploring different aspects of research evaluation. A comparative perspective was of particular interest, as academic studies on research evaluation normally focus on a restrictive sample of countries. The discussions in the various working groups frequently brought forward the notion of "diversities" . Even in a European context, there are many different university systems, evaluation regimes, political contexts and path dependencies (Ochsner et al., 2021). Furthermore, there are disciplinary differences in knowledge generation and dissemination
