Uneven coverage of journals in the major commercial citation index databases (such as Web of Science, Scopus, and PubMed) has strong effects on evaluating both researchers and institutions (e.g. the UK Research Excellence Framework or Times Higher Education ranking). While these databases primarily select based on process and content quality, there has been concern that their commercial nature may skew their assessment criteria and representation of journals outside of Europe and North America. However, there are not currently equal, comprehensive, multi-lingual, open source or non-commercial digital infrastructures.
