A scientometric analysis of the documentary array (DA) with Russian affiliation on the topic "citizen science" (CS) from the Scopus database is presented. The purpose of the study was to identify: the dynamics of the publication; organizations and authors leading in terms of the number of publica tions; the of journals in which the documents of the array are published; subject areas in which research is carried out; structures of interaction between organizations with which the authors of publications are affiliated, building a map of thematic areas of DA using the software CiteSpace. It is shown that the increase in the number of publications on the problem under study in the Scopus database is observed at the end of the 10th and continues to the present. The organization and author leading in terms of the number of publications in the composition of the studied DA are: V.M. Matrosov Institute for System Dynamics and Control Theory of SB RAS (IDSTU SB RAS, Irkutsk) and O.S. Zaikin (IDSITU SB RAS), respectively. The main subject areas to which the documents are related: Informatics; Agricultural and Biological Sciences; Social sciencies; Mathematics; Environmental sciences; Technique; Biochemistry, genetics and molecular biology, etc. (23 subject areas). The largest number of papers was published in the serial collections CEUR Workshop Proceedings (21 articles) and Communications in Computer and Information Science (16 articles). CiteSpace identified 27 groups of organizations conducting research with volunteers or analyzing the phenomenon of CS. For 13 of them, using groups of terms from titles, keywords and annotations, the main thematic focus of research is indicated. The data obtained indicate that Russian scientists are involved in Russian and foreign CS projects, within which volunteer computing is carried out; exploration of Space, environmental, medical and biological problems.
