  • DOI allows to identify and search for scientific data located on the Internet;
  • this number always remains the same and using it you can easily find a journal, article or book;
  • Digital object identifier considerably facilitates the procedure of citation of scientific publications, as its title, abstract and keywords are sent into the worldwide public database of scientific data International DOI Foundation ;
  • when quoting the article containing DOI with one of the journals included in Scopus, Web of Science or any other prestigious bibliographic database, the author’s and article’s data are also recorded in the database;
  • all journals included in Scopus, Web of Science and Springer, compulsorily assign their articles DOI;
  • increase in the number of author’s articles citations automatically increases its index of citing and personal Hirsch index – the most important scientometric indicators at the present stage of science development .
