Abstract: This paper presents bibliometric characteristics of the 386 most 
frequently publishing world universities and of a (partly overlapping) set 
of 529 European universities. Rather than presenting a ranking itself, it 
presents a statistical analysis of ranking data, focusing on more general 
patterns. It compares US universities with European institutions; 
countries with a strong concentration of academic research activities 
among universities with nations showing a more even distribution; a 
ranking of universities based on indicators calculated for all research 
fields combined with one compiled for a single field (oncology); general 
with specialised universities; and rankings based on a single indicator 
with maps combining social network analysis and a series of indicators. It 
highlights important factors that should be taken into account in the 
interpretation of rankings of research universities based on bibliometric 
indicators. Moreover, it illustrates policy-relevant research questions 
that may be addressed in secondary analyses of ranking data. In this way, 
this paper aims at contributing to a public information system on research 
universities.
