Metadata of issues of journals from the List approved by the Higher Attestation Commission (HAC) have been regularly posting for more than 20 years in the Russian Science Citation Index (RISC) based on bibliographic database eLibrary.ru. In March 2023, the journals from the Higher Attestation Commission List, in accordance with the recommendation of the Higher Attestation Commission, posted information on journal issues for 2022 in the Russian Scientific Journals (RNJ) database. In April 2025, by Order No. 337 of April 11, 2025 The Ministry of Education and Science of the Russian Federation has added a new requirement — registration of a journal from the List in the database of the Russian Center for Scientific Information (RCNI), which acts as the operator of the 'White List'. What additional opportunities do the RNJ and 'White List' databases create for applicants for academic degrees and dissertation councils in comparison with the capabilities of the RISC based on eLibrary.ru? What is the role of the RNJ base? How will correspond the ranking of the 'White List' (levels U1, U2, U3, U4) and the categories of the Higher Attestation Commission journals List (K1, K2, K3)?
