The present review and analytical article devoted to the III International Bibliographic Congress provides general information about the most acute problems of modern bibliographic activity and the Congress as a whole, offers points of view on the main debatable issues: about the MARC format, DOI and bibliographic reference, national bibliographic resources.

The problem of creating bibliographic products in electronic format is considered. The purpose of the article is to analyze local history bibliographic products as part of the content of the central libraries sites of the Russian Federation subjects.
It is established that the creation of bibliographic products in electronic format is empirical in nature. Most often, libraries create bibliographic databases and electronic guidebooks. Identification barriers that make it difficult for users to identify and use bibliographic products on library websites have been revealed.

The Bulgarian National Bibliography has been based on a tradition related to the normative support of its creation, development and potential for international cooperation. The Bulgarian National Bibliography has been created by law, which is strictly observed by St. Cyril and Methodius National Library. The rules and standards of bibliographic records and authority control, reviewed in the report, have been applied to the Bulgarian National Bibliography bulletins according to the IFLA international requirements. They give a good opportunity to the Bulgarian National Bibliography to participate in the international exchange of bibliographic and authority data.

The main directions of the development of the national bibliogra-phy in the modern world, the problems of the formation of the system of the national bibliography in Russia, issues related to the current national bibliogra-phy, retrospective national bibliography are presented. The activity of the IFLA Bibliography Section on the regulation of the activity of national bibliographic agencies and the creation of national bibliographic resources is covered. The article describes the activity of the National Bibliographic Agency in Russia (Russian Book Chamber), the National Library of Russia and their role in the creation of a national bibliography in the digital age.

 The article presents an overview of the problems that arise in the
process of practical application of the national standard regulating the rules of bibliographic description in bibliographic activities. Special attention is paid
to the features of the bibliographic description that have not received sufficient coverage in the standard. The article emphasizes that the standard is focused on a creative approach to the application of description rules. It offers various options, the choice of which depends on the specifics of a particular library, the purpose of the description and the information needs of the user. At the same time, the methodological decisions of the compilers of the bibliographic description are subjective. They depend not only on the tasks facing the bibliographic institution, but also on the qualifications of the bibliographers. It is necessary to adjust the adoption of methodological decisions by preparing normative and methodological materials that explain and detail the provisions of the basic standard. 

 The article is devoted to the analysis of the methodological potential of the
main provisions of the Doctrine of Bibliosphere, developed by A. V. Sokolov. It is noted that its source is the concept of Noosphere by V. I. Vernadsky, which has been developed in the works of N. N. Moiseev. The basis of the Doctrine is a number of provisions. The first one concerns the nature of bibliosphere. However, in different works by A. V. Sokolov, it is defined in different ways, e.g. as part of a social space, as a national system of infrastructural book and communication systems that have developed at the industrial stage of man-made civilization, as a part of the document sphere, as a supersystem of book and communication systems that ensure the reproduction, preservation and further development of the national book culture. The second proposition concerns Bibliologos, or Book Mind, as the governing principle of Bibliosphere. The content of the third provision is devoted to the identification of the conflict between book and digital culture. The fourth and final statement is aimed at revealing the humanistic nature of Bibliosphere. It is based on ideas on the humanistic nature of book.  The existing contradictions are analyzed. Theу include, first of all, the impossibility of the direct transfer of terminology and basic provisions of the theory of
Noosphere to library and bibliographic concepts due to the difference in the scale of these theories (Noosphere and Bibliosphere), as well as the applied nature of the latter. Secondly, the contradiction highlighted by A. V. Sokolov is considered as a local problem caused by the transition to new technologies. Its resolution is not of a key nature and does not determine the vector of development of librarianship and bibliography. Third, the author questions the validity of identifying Bibliologos as a governing principle within the framework of a theory based on the principles of scientific rationality, which excludes the appeal to mysticism. Fourth, it is noted that the humanistic nature of librarianship and bibliography is given not by the nature of the book, which is indifferent, but by library and library and bibliographic
activities aimed at the humanistic development of society.  

 As a result of the analysis of Doctrine, the author comes to the conclusion that the idea of creating a theory, the main provisions and methodology of which allow us comprehensive consideration of social, information, technological and ethical (humanistic) aspects of librarianship and bibliography is relevant for modern library and bibliographic science in the context of the transition to a new model of organizing librarianship and bibliography. The analysis of the Doctrine on Bibliosphere has shown that it can potentially become such a theory, provided that the contradictions and unresolved issues identified by us are successfully resolved. At the same time, from a methodological point of view, it is fundamental to return
to the positions of materialism and dialectics. 

 The influence of the quality of the bibliographic description on the search results in bibliometric data bases is considered. Three basic levels for
bibliometric assessments are proposed. The influence of bibliometric errors on the quality of assessments at each level is shown. It is noted that the level at which the work is carried out with specific authors is the most sensitive. The responsibility for the inaccuracy of bibliographic data in scientometric search engines lies on the generators of information resources of these systems. 

 This article is devoted to topical issues of increasing the efficiency of
a library website and the introduction of a data-driven approach. A data driven approach is considered as a management strategy for the development of a site in a web environment, based on data from web analytical tools as the basis for decision-making. The author has developed a website management model that includes the sequence of actions: goal setting, performance monitoring, data analysis, planning, decision-making, implementation of changes, control. The proposed management model allows one the application of a unified approach and management tools to a library website, depending on the goals set, identify current problems and, on the basis of objective decisions, develop its further development strategy in the information environment. The article presents the results of approbation of the model on the example of website management of the State Public Scientific Technological of the Siberian Brach of the Russian Academy of Sciences and notes the advantages of managing a library website based on a data-driven approach. 

The article is based on foreign collections of Russian printing materials. Their analysis has shown that some of the most active public associations in
Russian China were the Cossack ones, which existed in Harbin, Shanghai and
areas adjacent to the Soviet-Chinese border. The Cossacks paid great attention
to printed publications. They published articles and information about their
activities in the Russian press in China. The Cossack Union in the Far East
developed a special publication activity. The Siberian, Transbaikal, Amur and
Ussuri Cossack troops (associations) had their own press organs. 

 The purpose of the article is to fill the gap in the study of such an aspect of the activities of Russian-language foreign publishing houses as the release of literature for children and youth. Such activity is reflected very poorly in book research. This is primarily due to the fact that there were very few specialized publishing houses for the production of children’s literature in the Russian Diaspora, and their archives were either fragmentarily available for study or were absent altogether. At the same time, the publication of children’s
literature in Russian in the first post-revolutionary years was of great demand
both in the emigre community and in Soviet Russia, which was unable to satisfy the urgent need for such literature. The article presents the results of a search for information about the release of Russian-language children’s literature in the Russian Diaspora in the first half of the 1920s, using the example of the activities of one of the most notable emigrant enterprises – I. P. Ladyzhnikov, who was in 1906–1932 in Berlin. Being in essence a universal publishing house, it was in the 1920s actively involved in the process of publishing literature for children, having its own unique circle of authors, illustrators (both Russian and foreign), creating a specialized children’s department in its structure, publishing a children’s book in very solid volumes. 

The national bibliography is a comprehensive and systematic catalog that gathers and records the information of all the publications in a country, and serves as the base for monitoring and managing all the information related. China National Bibliography in modern times has been continuously developed and improved, thanks to the legacies from its past and the experiences of other countries. The present paper first reviews the past and the present of China National Bibliography, then discusses the progress of researches on the application of Functional Requirements for Bibliographic Records (FRBR), and finally explains the survey on the feasibility of adopting the new cataloging standard RDA in China. Although the FRBRization of China National Bibliography, to a certain extent, facilitates the readers’ use, we argue that the FRBRization of the existing MARC data cannot realize all the ideas FRBR creates. There are some problems, such as the distinctions between works and expressions, the construction issues of the bibliographic and authority data. In the process of implementing localized RDA in the cataloging of foreign materials of all languages and types, the National Library of China conducted an investigation into the feasibility of implementing RDA in the cataloging of Chinese literature, finding that although there is not a vast gulf between RDA and current Chinese cataloging standards, a lot of problems do need to be resolved both theoretically and practically. First, the Chinese national standard “Resource Description” of the day and the CNMARC standards need to be improved. Second, it is urgent to reduce the increasing manual workload of the catalogers caused by adopting RDA. Third, both the staff force and the system reserve ability of the member libraries under Online Library Cataloging Center of China should be taken into account. Fourth, RDA would add new data elements, thus the initiation of this new standard simultaneously requires updating and transforming the integrated library system. Last but not the least, the application of RDA also requires the development of corresponding online toolkits to improve the cataloging efficiency.

The material aims to introduce the Bibliographical Data Working Group – part of the Digital Research Infrastructure for the Arts and Humanities (DARIAH-EU) – and to feature projects fulfilled by this group. This working group since 2019 brings together specialists (as of today: 38 researchers) from a number of different countries and the main goals of the group are to foster the development of cooperation between bibliographies and serve as a platform for knowledge exchange aimed at bringing together creators of bibliographical data, scholars interested in using those resources in data-driven research, and theorists of bibliography and documentation. In the presentation two projects are described in detail: 1. the report “An analysis of the current bibliographic data landscape in the humanities: Bibliodata curation, research, and collaboration; 2. The project “Multilingual encyclopaedic dictionary of types of documents”. The purpose of the article is not only to describe these projects but above all to invite Congress members to collaborate on them.
