Visibility of peripheral journals through the science citation index

摘要

The effect of the inclusion of a journal into the SCI source journals selection on the journal's “visibility” was studied by analyzing the number of independent citations of the articles published in two journals (Croatica Chemica Acta (CCA) and Roczniki Chemii(RC)) in two periods. The “echo factor,” i.e. the citation count normalized by the size of CCA and RC publication source pools and of SCI citing pool, did not show any increase upon the inclusion of either of the two journals into SCI selection: for CCA it even showed a decrease and for RC remained essentially constant. A statistically significant increase in the SCI citing pool, that took place around 1976, was also noticed.
