Are multi-authored articles cited more than single-authored ones? Are collaborations with authors from other countries more cited than collaborations within the country? A case study.

Abstract

Based on LUC evaluation data we investigate the citation output of single-authored articles versus the output of articles with two or more collaborators. This is done for ‘citable’ articles published in journals covered by the JCR (ISI), and for all other articles (published in non-ISI journals, in conference proceedings or in edited books). Citations to books are not included in the study. We further compare citation results for collaborations within the country and with scientists from abroad. Results: multi-authored articles have usually higher citation frequencies than single-authored ones, but this relation does not hold in all cases. On the other hand, it seems favourable (in the sense of receiving more citations) for a small university in a small country, to collaborate with scientists from abroad.
