In the Humanities and Social Sciences (HSS), the monograph is an important means of communicating scientific results. As in the field of STM, the value of scholarly output needs to be assessed. This is done by bibliometric measures and qualitative methods. Bibliometric measures based on articles do not function well in the field of HSS, where monographs are the norm. The qualitative methods which take into account several stakeholders are labour intensive and the results are dependent on self-assessment of the respondents, which may introduce bias. In the case of humanities, the picture becomes even less clear due to uncertainties about the stakeholders. This dataset consists of over 25,000 downloads by more than 1,500 providers, spread over 859 monographs.
