In this appendix we provide data about citations/publication for the countries studied in this article. Although the types of documents and the period of publications correspond, for practical reasons the databases do not. Hence, the reader should not pay too much attention to this data. It just serves to operationalize the phrase “rather low number of citations per publication” as used with respect to the Russian Federation, China and India. Just for the readers’ information we mention that the Pearson correlation between the ratio of institutional e-mail address and the non-institutional ones (column 2 of Table 8) and the number of citations per publication (column 3 of Table 8) is 0.82, while the Spearman rank correlation is 0.77.
