Ю. И. Чавыкин The author discusses the findings of the bibliometric study of the national document flow (as presented in the RISC database) on the issues of open access to scientific and research information. The general volume of microflow made 1,076 publications of various types, including articles in periodicals and serials, as well as books, conference proceedings, reports, theses, and deposited manuscripts. The journal articles made the main bulk (74%) followed by the proceedings (20%). The dynamics demonstrates the upward trend though the growth rate is rather low. The publication dispersion in periodicals is characterized. In general, it can be described by Bradford – Vickery law. The most productive (core) journals with the greatest number of relevant publications are defined. All of them are not specialized publications. The subject areas are defined. The analysis of the first and second zone journals demonstrates that they belong to 19 subject headings of the State Rubricator of Sci-tech Information which evidences on the interdisciplinary character of the problem under study.
