Schmoch U, Schubert T. Are international co-publications an indicator for quality of scientific research? Scientometrics 2008;74(3):361-377
The article deals with the role of internationally co-authored papers, or co-publications. Specifically, the authors compare, within a data-set of German research units, citation and co-publication indicators as proxies for scientific research quality assessment. They also address the issue of the relationship between citations and co-publications. Their results suggest that, although there is a strong partial correlation between citations and co-publications, co-publication indicators cannot be used as a proxy for research quality assessment, Thus, concerning this question, there remains a primer on citation analysis.
