The study aims are to conduct a systematic quantitative analysis of Open Access (OA) Instruments and Initiatives, justify and develop the methodology for calculating the index of countries' involvement in the Open Access movement. The authors identified all the significant OA-Instruments and OA-Initiatives, which were counted on the basis of the records in their OA-registers. Consolidation of records in these registers, according to literature data from the moment of their launch, made it possible to identify important patterns and features of the evolution of the OA-movement. The proposed methodology when applied to all countries of the world as of 2017 and 2019 allowed the authors to rank and classify them according to a degree of their involvement in the OAmovement. The article affirms that the proposed methodology in the context of regular comparative analysis of the benchmarking tables with setting the target integral indicators for the lagging countries is very convenient for the development of Global or Regional OA-Strategies. So the authors define the concept of the International or Regional OA-movement Scoreboard, underlying the development of these strategies.

In the Chapter, we explain the phenomenon of the coronavirus publication race, analyse a number of typical bibliometric articles, which are structured according to the standard principle-presenting ranked lists of publications distributed by countries, journals and institutions, as well as lists of the most cited articles. Twenty-one online platforms were identified, on which the largest number of articles on coronavirus topics were published, of which two samples were identified as of 15 December 2020 (82 articles with the term "COVID-19" in article titles and 63 articles with the term "Coronavirus" in article titles) articles with over 1,000 citations in Elsevier journals and over 500 times on other online platforms. These articles were categorized by authors, countries and institutions. The samples of articles were reduced to a single sample with one hundred and twenty-five articles that did not overlap in two samples, on the basis of which a detailed analysis of the structures of international co-authorship with the identification of thirty-one countries, the authors of which participated in international collaboration on the coronavirus research, was made. For this analysis, a square symmetric matrix of international co-authorship was developed. A content analysis of highly cited publications on SARS-CoV-2 was carried out, revealing overlapping topics, for which the multi-topic factor proposed by us was calculated.

In the modern world there has been change in education environment and education technologies, which has led to new concepts and tendencies in training and education. The purpose of this research is to explore evolution of terminology in distance, open, online education and learning. The change in use of the terminology is analysed through the Google Books Ngram Viewer that allows to define frequency of the use of the terms in six publications corpora for the certain period. The research identifies tendencies of the use of the terms in the sphere of education in different language groups compared and reveals interrelation between the change in the use of the terminology and economic, social, political and technological factors.
