Which European universities and research centres are most prominent in research on European Union (EU) interest groups? What are the theoretical perspectives employed currently in this scholarship? What research designs do scholars employ to study and investigate EU interest groups? And finally, what are the academic works that constitute the core building blocks on which researchers of EU lobbying build their theoretical arguments and empirical research? We answer these questions by analysing an original, built-for-purpose dataset providing information on the theoretical approaches, research designs and bibliographic references employed in 196 academic articles published on the topic of EU lobbying and interest groups in 22 European and American journals of political science and public policy. The dataset also contains information about authors' academic affiliation and Ph.D.-awarding institutions. We combine two approaches employed in the literature on systematic analyses of a discipline: the research synthesis and meta-analysis approach, and the bibliometric approach.
