The historical aspect of the State System of Scientific and Technical Information is explored.

In the second part of the study, the authors analyze the publication activity related to the use of the term “scientific legacy” in international academic literature indexed in the OpenAlex database. The comparative analysis revealed the key differences in approaches, semantic interpretations, and thematic emphases between the international and Russian scholarly practices. Particular attention was given to identifying the features of the conceptualization and interpretation of scientific legacy in the international context which enables to assess theoretical and methodological framework of this phenomenon on a global scale.
The study methodology includes bibliometric methods and statistical processing of publication metadata. The findings demonstrate that while the interest in scientific legacy study in the Russian Federation is growing, the international scholarly practice exhibits the broader range of contexts for using the term. Notably, Russian academic literature has significant gaps, particularly regarding the sociocultural interpretations of scientific legacy. At the same time, the national trends in publication activity corresponds with international patterns, and Russia’s position in this domain can be characterized as stable and promising.
The authors emphasize the need for strategic collaboration of Russian researchers and global scholarly community to study and promote national scientific legacy globally. This approach will not only enhance awareness of Russian scientific achievements but also strengthen their contribution to shaping the global scientific discourse.

The paper addresses the methodological problems of evaluating the processes and outcomes of the international integration of national science, using the case of Russian research in the field of media and communication. Within the study, several questions emerge that, while looking seemingly simple and straightforward under formal approaches, in fact call for detailed and critical examination. In particular, the working definitions for the concepts “international integration,” “article on media,” “international journal,” “Russian author,” and “Russian article” had to be developed to ensure accurate data interpretation.
To select integration parameters, quantitative data from the Web of Science (WoS) were used. However, the analysis went beyond standard indicators of publication activity and citation. Combinations of different indicators were applied, e. g. differences in citation between all journals and foreign journals indexed in the core WoS databases, the ratio of publications in formally versus genuinely international journals, the pool of sources cited by Russian authors, and others.
The authors propose solutions to the key methodological challenges: refining publication selection criteria through combined search strategies and manual filtering; developing journal classification system to distinguish between formally and actually international publications; and creating typology of formally Russian authors based on their actual geographical affiliation. Several additional methodological issues were also addressed to obtain tangible results in the analysis of international ties, including authors chronological clusterization and countries grouping.
This part of the article focuses on the key methodological problems mentioned above, excluding the differentiation between formally and factually Russian authors and articles.
The findings demonstrate that without in-depth analysis of these methodological issues, relying on the indicators of international databases may lead to significantly distorted representation of reality. The proposed approaches can be adapted to refine scientometric assessments in other academic fields, particularly in the social sciences and humanities.

In the recent decades, the developments in information and communication technologies have cardinally changed science and engineering and caused the information flows snowballing. The education industry reacted with new educational standards oriented toward application of technologies in professional and quasiprofessional training which requires proactive independent use by learners. Within the contemporary context, the efficient intellectual activity is impossible without ICT tools. Computer programs enable to organize work with information sources, e. g. bibliographic managers used to preserve and process bibliographic information. Despite the diversity of bibliographic managers available, sometimes special targeted solutions are needed. The author discusses implementation of bibliographic manager through the instruments of any modern web-browser, e. g. HTML, CSS or JavaScript. Intentional control of the instruments enables to provide product functionality over the wide range of platforms. Independence of external factors and application of web-standards enable autonomous work with information resources on Pcs and use of the product as a component of Internet or intranet sites to visualize document collections and information materials.

The spiraling information flows and information preservation demand indepth analysis of criteria to separate valuable data from those with no value, to determine preservation time, and to identify the entries. The purpose of the study is to explore into the selection criteria and to specify those necessary and sufficient to be used by scientific libraries to evaluate and differentiate incoming information. Based on the analysis, the author specifies the criteria for scientific data acquisition and evaluation in the context of time and format diversity; the criteria were grouped based on utilization: for resource selection, data evaluation and inclusion into the database to be stored. The procedures for each criteria and related librarian competences are reviewed. The author specifies the criteria most relevant to scientific literature selection (scientific/historical value, legal assessment) and the secondary ones (completeness, duplication, etc.). The related librarian competences are identified. The author also examines challenges that hinder application of individual criteria and proposes the solutions.
The study findings can be useful for librarians, archivists, and information specialists to acquire and analyze the data for further digital preservation.
The study is completed within the Library’s for Natural Sciences of the Russian Academy of Sciences R&D project “Improvement of methods of long-term preservation of scientific information as the basis of knowledge in the natural sciences”.

The authors discuss the results of updating SRSTI subject classes 34 Biology and 76 Medicine and Healthcare. Within these classes, the subject headings to a great extent appear to be associated. Within the SRSTI master version, the mentioned classes are well structured. However, when preparing 2025 SRSTI master version, the analysis of their subject and structural organization evidences on t he n eed t o m ake t he s et o f c hanges a nd a mendments to the Rubricator due to the rapid development of fundamental and applied disciplines within the earth sciences. To update class 34 Biology, 52 changes had to be made to its structural organization; with new subject headings making 67.3% of changes and 32.7% updates of subject headings naming. Significant changes are made to the areas of developmental biology, cell biology, plant physiology, microbiology, virology and anthropology. Thus, SRSTI master version class 34 Biology is to comprise 25 subclasses systematized with 306 subject headings on the 3-rd hierarchical level. To develop class 76 Medicine and Healthcare, 51 changes are to be implemented into the structural organization, with new subject headings making 70.6%, 25.5% updates to the headings naming, with 3.9% headings excluded. To the utmost, the changes are made to the subject areas of medical cybernetics and informatics, clinical medicine, clinical pharmacology, hygiene and epidemiology as well as healthcare organization and administration. Finally, class 76 Medicine is to comprise 10 subclasses, represented by 189 subject headings on the 3-rd hierarchical level. 182 new polyhierarchical links between the subject headings have to be introduced to the SRSTI reference aids upon the updates to class 34 Biology and 76 Medicine and Healthcare; with the most frequent link “see also” which evidences on the serious intensification of interdisciplinary component within the structure of SRSTI 2025 master version.

In the context of digital transformation of the library sphere and gradual implementation of artificial intelligence technologies into library practice, the challenge of effective interaction with neural networks and high-quality promptsmithing is increasingly relevant. The author proposes his model of communication with artificial intelligence, based on the principles of Benevolence, Rationality, Refinement, and Epistemology, and demonstrates its practical application and effectiveness. The model is developed as a methodological approach to prompt engineering in library practice. The study methodology comprised model development, engineering of the series of prompts of varying “strength” based on its principles, and testing with 6 neural network models to accomplish the task of bibliographic data analysis. The testing results demonstrate direct correlation between the quality of neural network response and the level of prompt sophistication based on the proposed model. The practical significance of the study lies in offering methodological framework for improving the efficiency and quality of interaction between library specialists and artificial intelligence, as well as the possibility of using the model to develop practical recommendations and educational programs on prompt engineering in the library sphere.
