DOI (Digital Object Identifier) is an important tool for organizing the storage of scientific texts. Assigning scientific books or publications with DOIs makes their search much easier for researchers around the world. "Bulletin of RSMU" gave DOIs to all papers published in both language versions of the journal in 2016–2017. We see the first results: regular reports from CrossRef (an international agency that organizes work with identifiers) show that some papers of the authors of the "Bulletin of RSMU" already has several tens of views thanks to DOIs.
