OpenAlex has recently emerged as a leading alternative to proprietary bibliometric sources. However, concerns remain regarding the quality of its metadata, especially the institutional profiles which are crucial for evaluating organizations. This study assesses the quality of affiliation data in OpenAlex using German research institutions. Publications from top-tier journals were…
« OpenAlex is a freely available bibliographic database that can be used for bibliometric studies. In this study, we compared certain field-normalized citation scores (NCS) from OpenAlex with those from three commercial databases (Web of Science, Scopus, and Dimensions). We were interested in the question whether the NCS from OpenAlex are…
« This study aims to compare the geographical and disciplinary coverage of OA journals in three databases: OpenAlex, Scopus and the Web of Science (WoS).

This article therefore assesses changes in…
« This study investigates the potential of citation analysis of Ph.D. theses to obtain valid and useful early career performance indicators at the level of university departments. For German theses from 1996 to 2018 the suitability of citation data from Scopus and Google Books is studied and found to be sufficient…
« Encyclopedias are sometimes cited by scholarly publications, despite concerns about their credibility as sources for academic information.
