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.
