Double effort = Double impact? A critical view at international co-authorship in chemistry

  • Wolfgang Glänzel
  • András Schubert


An attempt is made to find statistical evidences of the relation between international co-authorship and citation impact. It was found that international co-authorship, in average, results inpublications with higher citation rates than purely domestic papers. No correlation has beenfound, however, between the strength of co-authorship links and the relative citation eminence ofthe resulting publications. International co-authorship links in chemistry, as represented by thewell-known Salton's measure, displayed a characteristic pattern reflecting geopolitical, historical,linguistic, etc. relations among countries. A new indicator, representing also the asymmetry ofco-authorship links was used to reveal main "attractive" and "repulsive" centres of co-operation.
