Measuring scholarly impact and societal relevance in the humanities and social sciences can be done in several ways. Here we will look at a collection of e-books from the FWF-E-Book-Library, which is made available through the OAPEN Library. In 2014, 146 books of the FWF-E-Book-Library collection were made available via the OAPEN Library.The analysis is based on COUNTER compliant download data. This means that downloads by automated systems ('bots') and other types of suspicious download behaviour is discarded from the reports. The data of the 28,139 downloads used for this analysis originated from 23,652 IP addresses. It is clear that many providers use several IP addresses: the IP addresses were linked to 2,839 provider names. Where no information about a provider could be found, the download data was omitted.

A concept version of the article with an explanation of the variables and the research project has been deposited by Ronald Snijder.

The data have been deposited in both Excel and LibreOffice file formats.
