The problem of identifying the component content of the ecology of book culture is considered. The main eco-cultural aspects of book culture are analyzed through the identification of various loci, including specific relationships between actors in the book space. It is shown that the problematic situations arising in these loci are largely associated with the underestimation of their eco-cultural aspects.
The purpose of the article: to substantiate the main functional and semantic directions of activity in the field of ecology of book culture.
To achieve the goal, a problem-thematic analysis of individual parts of book culture was used; exemplification method, clarifying the presented provisions; functional-activity approach in substantiating specific directions of ecological and cultural activity in the space of book culture.
Presented eco-cultural aspectation of book production and logistics, qualities of book text, features of interaction with the reader, problems of the information environment of book culture, loci of book existence, processes of transformation of book space, including in the context of multimedia. In the dynamics of development of the ecology of book culture, all designated components interact in functional and spiritual-semantic meaning.

The purpose of the article is to present the results of the study focusing on the role of ego-documents as a resource for the formation and maintenance of regional identity, as well as the analysis of their use in the practices of cultural and scientific institutions, touching Siberia as a case study. Personal testimonies such as diaries, letters, and memoirs offer unique insights into how historical events and processes were perceived by their authors, making them essential elements of cultural heritage. In the context of globalization and cultural standardization, where regional identities face the challenges of universalization, ego-documents can be used in the creation of local narratives that reinforce regional self-awareness.
Siberian libraries, archives, and museums actively incorporate ego-documents into the regional cultural heritage by collecting and publishing them, organizing exhibitions that present personal opinions on the history of the region. These institutions foster a sustainable regional memory and support cultural diversity, allowing Siberian residents to feel concerned in their local history. Incorporation of ego-documents into the cultural heritage also serves as a tool through which regional elites can create narratives that highlight the unique features, values, and traditions of the region.

The purpose of the article is to provide a historical analysis of the emergence and functioning of the Russian library in Zurich, organized by members of the Russian colony in 1870, and also to show that the public discussions that took place at the end of the 19th century are very similar in style to modern Internet discussions and , therefore, can be considered as a prototype of the latter.
The article is devoted to the history of one of the first Russian public libraries abroad, located in Zurich (Switzerland) in the first half of the 70s of the XIX century, which was not just a library, a repository of books, but in fact, a place where the formation of two main directions of the Russian revolutionary movement of that time took place: "Bakunism" (anarchism) and "Lavrinism" (populism), named after their leaders M.A. Bakunin and P.L. Lavrov. The first part of the article presents the history of the emergence of the library, provides the composition of the book collection, discusses the methods of its replenishment, accounting, tells about the fates of the creators of the library, first of all, M.P. Sazhin (Armand Ross), the actual creator of the library, the main associate of Bakunin, who not only collected the book collection, but also organized a discussion club at the library, where sharp and topical discussions took place about the library itself and the revolutionary events in Russia and Europe. Such discussions were very emotionally charged, topical in content, and sharp in meaning. The second part of the article is devoted to the content and analysis of these discussions, where the idea is first put forward that they became the prototype of discussions in the Internet space of the 21st century. 

The purpose of the article is to form an idea about the release of educational and methodical literature on disciplines taught in various educational institutions of the Far East in the pre–revolutionary period. In this regard, the author provides statistical information on the release of literature by year and city of the Amur Educational District, demonstrates the variety of topics of published works, the structure and content of a number of publications. The source base was data from volumes 1 and 2 of the "Consolidated Catalog of the Siberian and Far Eastern Books" (Novosibirsk, 2004). When writing the article, various research methods were used: bibliographic, statistical, analytical-thematic, historical-retrospective. Generalized data on statistics and topics of educational and methodical publications published in the printing houses of the Far East in the pre-revolutionary period are presented for the first time. The results of the statistical analysis indicate that Vladivostok was the leader in publishing such literature. In other cities of the region, significantly fewer works were published.
Among the textbooks, textbooks, lecture courses, anthologies were works on linguistics – Chinese, Korean, Tibetan, Japanese, Mongolian, English and French; Korean, Mongolian, Japanese literature; history of China and Japan; political science, military affairs, law, political economy, economics, agriculture, geography, meteorology, theology. A significant mass of publications consisted of programs, reports of educational institutions and societies, charters, instructions, protocols, rules, regulations, works on the history of educational institutions, as well as works dedicated to various anniversaries. The most actively published educational literature on linguistics. There were primers, textbooks, anthologies, lecture courses, grammars, etc. History and geography are mainly represented by lectures, state and law programs.

Nikolai Chuzhak’s (N. F. Nasimovich, 1876–1937) – a famous Marxist publicist – literary criticism is, at the first glance, already studied enough by theorists in bibliology and literature. However, the fragmentary nature of researches and lack of the profound scientific comprehension of his critical heritage specifics dictates the necessity to bring into the system the data about his publications in Siberian periodicals and collections issued when he stayed in Siberia and the Far East from 1908 to 1922, that being the purpose of the article.

Chuzhak's literary and ideological reflection on the history of Siberian philology began to reveal itself in the early period of his Siberian exile, when he was in ideological opposition to local criticism. However, gradual research and immersion into the Siberian context and endeavors to understand the specificity of this faraway land literature began to form the position of not only a “stranger” but also a “cultural mediator.” It became fundamental that N. Chuzhak comprehended Siberian literature within the Marxist theory, which set an imprint on the methodology and conceptual model of his critical texts.

Despite obvious tendentiousness of the main provisions, the critic’s undoubted merit was, as we see it, that for the first time he raised the question about the necessity of studying Siberian literature as a phenomenon of poetics. Chuzhak's creative work as the critic of Siberian literature, comprehended on a systemic level, represents a kind of a “metatext”, revealing both the evolution and stable typological features of different periods of his literary work.

The article is devoted to the identification and analysis of books by ancient authors published in the 16th–19th centuries of the recent recreated in the second half of the 19th century book collection of the Radziwill princes of the Nyasvizh fee tail. The origins of this privately owned book collection on the current territory of Belarus go back to the 16th century. The article presents an analysis and brief description of the identified copies. More than 130 editions have been identified, including works of ancient poets (Homer, Virgil, Horace, Ovid), fabulists (Aesop), rhetoricians (Cicero), historians (Thucydides, Xenophon, Caesar, Cornelius Nepos, Sallust, Livy, Plutarch, Eutropius), theologians (Justin Martyr, Jerome), philosophers (Plato, Seneca), playwrights (Terence) in both ancient (Latin and Greek) and modern European languages (French, German, Polish, Italian). The books of ancient authors in the collection reflect the diversity of European book publishing of the 16th–19th centuries: editions of the printing houses of France, Germany, Italy, Switzerland, Holland, Polish–Lithuanian Commonwealth are presented here. A special place is given to the author's and owner's records of books left in the margins based on materials from the fund currently stored in the Central Scientific Library named after Yakub Kolas of the National Academy of Sciences of Belarus. The presented variety of editions of ancient Greek and Roman authors demonstrates the constant interest of the Radziwill princes in the ancient literary heritage underlying European culture.

At present, the problem of history of the State policy for the promotion of science is of interest to many scientists. However, the features of the origin and formation of the domestic legislation in the sphere of popular scientific knowledge promotion through libraries are not enough studied. The purpose of the study was to identify and analyze the most significant legal documents in the field of science and technology popularization, including those addressed to libraries. The source base was an amount of legislative acts from 1917 to 1941. As the result of the study, the author determined that the development of the domestic system of the State regulation of popularization of science began in the early years the Soviet state existence. The dissemination of scientific knowledge into the society through the system of non-formal education was regarded as the necessary means of awakening the activity of masses in the process of their participation in the Cultural Revolution, as well as the restoration and construction of the national and agricultural economy. Normative legal acts concerning libraries were developed in accordance with the national policy of the party and the government. The legislative authority charged libraries to participate in the propaganda of natural, technical, and agricultural knowledge, and to promote self-education of all citizens. The official documents of the given period recorded specific forms and methods of science popularization, including: acquisition of collections of popular science literature, preparation of lists of recommended publications, organization of traveling exhibitions, creation of scientific circles, conducting loud readings and excursions, participation in cultural and library trips, etc. 
The data obtained in the course of the study confirmed our assumption that in addition to serving the ideological order of the State, the librarianship in the USSR was legally entrusted with the functions of popularization of general scientific knowledge already in the early Soviet period.

The purpose of the article is to work out approaches to the creation of the conceptual apparatus for determining the conditions and directions of the development of ecosystems of scientific creativity in the conditions of progress of collaboration between scientific, library, educational and publishing sectors of the economy. The article reveals the methodology of the terminological approach, shows the importance of its combination with scientometric analysis. It presents the works of the Research Department of Library Science of the Institute of Scientific Information on Social Sciences of the Russian Academy of Sciences (INION RAN) to the creation of the conceptual apparatus of regional ecosystems of scientific creativity in such areas as the development of state standards and publication of abstract, information and analytical materials.  The significance of the terminological standard "Bibliometric indicators. Terms and definitions, measurement structure", the first edition of which was prepared in accordance with the national standardization plan for 2024. The grounds for the creation of the standard, the main goals and objectives of its development are presented, the characteristics of the object of standardization are given, the scope of the standard and its technical and economic efficiency are shown. The terms related to the bibliometric assessment of young researchers’ activities, including foreign ones and the creation of the system of reliable information are noted. The importance of the INION RAN collection "Actual problems of library and information sciences" (2024) in the study of the modern foreign terminological system of scientific, library and publishing activities is shown. Attention is drawn to the presence of the subject index to the collection of 249 lexical units based on the analysis of 285 works on library and information sciences by American, German, English and Chinese researchers. The potential of the Youth Scientific Laboratory of the Institute of Scientific and Technical Information of the Donetsk People's Republic for elaborating the concept of forming regional ecosystems of scientific creativity is marked. Along with the study of the conceptual apparatus of the ecosystem of scientific creativity based on the terminological approach, the program for further monitoring and analysis of ecosystems of scientific creativity, as well as the list of terms, are presented.

In the structure of the foreign publications collection of the traditional format stored in SPSTL SB RAS, journals have always been the predominant type – more than 80 %, therefore, since the 70s of the last century, the Depository Department (at present – the Book Storage Department) has permanently participated in studies to correct principles of its formation and organization. Since the early 1990s, acquisitions to this segment of the collection began to decline sharply, interdepartmental cooperation and coordination of libraries in the system of depository storage of library collections fell to the ground. The bulk of journals migrated into the electronic environment, interpreted as an undoubted achievement. However, in the conditions of modern sanctions politics on the part of Western countries the situation has cardinally changed. Large-scale foreign providers have left and continue to leave the Russian information space. As a result, on the one hand, gaps have formed in the collection, which are impossible to fill, as well as to maintain the completeness of the repertoire. On the other hand, the value of many publications accumulated becomes more and more doubtful due to the total and complete obsolescence of information they contain and absence of any historical and cultural value. The purpose of the article is to give the notion about the evolution of approaches to the formation and organization of this collection basing on the results of undertaken researches. When working with the initial material the authors used methods of observation (for to collect data), statistical analysis (data registration, processing and systematization, etc.), comparative and system analysis, as well as that of document sources analysis, including certificates and reports on scientific-research themes. 

The purpose of the work: In the previous article on this topic, we considered such areas of digital marketing in the library user services: a) search engine optimization (SEO); b) engagement marketing; c) advertising on social networks. In this article, we will analyze: a) thematic and behavioral advertising; b) retargeting; c) banner, text and video advertising; d) email marketing; e) influence marketing; f) mobile marketing. The research applies the following methods: content analysis, conceptual modeling, comparative analysis, problematization. Conclusions: Because of the fact that the use of digital marketing has not yet become the norm in most libraries and only its individual elements are used, the systematic approach to its application, structuring of its goals, methods and means, and the distribution of duties and responsibilities among employees of the marketing direction are in need. Accordingly, at the present stage of the formation of the digital society, a comparative analysis of different libraries usage of the described digital marketing directions as an important component of phygitalization of library user services is necessary.

The purpose of the article is to present modern methods and peculiarities of information resources collection disclosure in electronic catalogs of scientific-technical libraries. On the example of collections in the electronic catalog of the State Public Scientific and Technical Library of Russia (GPSTB of Russia) methods and technologies are shown, which allow to better reveal the collection of scientific and technical library, to provide convenience and personalization of information provision for users.
