Due to the increasing importance of publication activity metrics, many organizations offering questionable publication services have appeared on the market. These publishers mislead potential authors by promising a quick and easy way to publish their research results.
As a rule, these companies promise to prove their scientific value by indexing papers via Universal Decimal Classification (UDC) and Bibliothecal-Bibliographical Classification (BBC), as well as by publishing ISBN materials in the Russian Science Citation Index database.
Please note that these features have nothing to do with expert evaluation of papers and do not confirm the scientific value of a journal.
