Our thanks go out to Bilyana Yavrukova, Deputy Director of the biggest scientific library in Bulgaria - Sofia
University Library "St. Kliment Ohridski" who has translated the Leiden Manifesto into Bulgarian. It was also just
published in the Bulgarian journal Nauka: Лейденски манифест за научни метрики, Nauka, 2020, 2, p. 12-15.
There have been many discussions in Bulgaria concerning the evaluation of scientific publications and the work of Bulgarian researchers and there is a prototype Bulgarian citation index under development.
