We consider the current situation to the indexing of Russian publications in international citation indexes and problems that lead to the absence of a number of publications in search queries. We show some examples of incorrect registration of the articles regarding the indication of affiliation of the authors for Russian journals indexed in the Web of Science and Scopus, as well as in the database Medline. We compare the loss of publications for various countries, which journals in Scopus are Medline-sourced. A series of measures to streamline the situation with the definition of authors affiliation in the international databases is proposed.
