When selecting world scientific serials for certain disciplines in the natural and technical sciences, the indicators of selected publications citation in specialized journals and the specialized journals citation in the selected publications are used. The study was conducted within the topics “Energy security and energy conservation, energy efficient technologies and engineering». Total citation in individual specialized journals was calculated along with the “discipline impact factor” - an indicator similar to the impact factor having in its numerator the value of citation of journals in the selected specialized journals rather than the whole range of journals being indexed by JournalCitationReports®. The serials were also selected by their total citation of the selected specialized journals. The indicator similar to the “discipline impact factor” is calculated as the fraction of the number of the serials’ links to the specialized journals publications in “the citation window” made by the serials being assessed on the specialized journals publication within the “publication window” and the citing publications in “the citation window”. In all the cases, the citation window equals one year, and the publication window equals “5 + 1” years, i.e. five years prior to the year when the links are being recorded.
