Content and demand of the "Scientific Heritage of Russia" Digital Library as an Element of the Common Digital Space of Scientific Knowledge

The authors offer the comprehensive analysis of the "Scientific Heritage of Russia" digital library (DB SHR) as a model element of the Common Digital Space of Scientific Knowledge (CDSSK). Established under the initiative of the Russian Academy of Sciences, the library provides open access to digitized scientific publications, archival documents, museum collections, and multimedia resources related to the work of prominent scientists. The DB SHR developmental stages are discussed, including its transition to the modern technological platform based on ontological approach and linked data principles. This upgrade has enhanced search functionalities, enabled the integration of diverse scientific resources, and expanded navigation capabilities. Special attention is given to the library's structure, which comprises administrative and user modules, as well as unique features such as advanced search across interconnected objects. The analysis covers the library's content distribution across thematic areas (natural sciences, humanities, and technical sciences) and includes statistical data on content demand from 2022 to 2024, showing a significant increase in full-text publication access (over 200%). Future development prospects for the DB SHR include expanding multimedia content, broader utilization of named connections between diverse objects, and enhancing search interface. Particular emphasis is placed on long-term digital heritage preservation and ensuring sustainable access to scientific resources for future generations of researchers.
