The paper aims to detect publication contributions of editorial board members (EBMs) to academic journal ranking as exemplified by Russian LIS serials divided into three groups according to their authority. To reveal the EBMs' contribution in each group, papers by EBMs in their parent journals as well as other sources were studied with comparative analyses of EBMs' papers in parent journals and papers by other authors in the same journals. The Russian Science Citation Index (RSCI) was used for collecting indicators that reflect journal ranks and scholarly output of EBMs. We found no relationship between journal ranking and a share of EBMs' papers in a parent journal. Citation analyses of EBMs' papers as well as citations of parent journals made by EBMs from other sources reveals a significant effect of EBMs on the rank of top-tiered and low-tiered journals pointing at active participation of EBMs in the development of parent journals. Zero or even negative impact of EBMs' papers on the journal rank is registered in the middle-tiered group implying formalistic engagement of researchers to join the editorial boards, lack of interest in the journal work, or possible violation of the publication ethics by publishing poorly cited or uncited papers in parent journals due to less strict peer-review processes. The paper adds to a better understanding of the nature of journal ranking, particularly, impact factors, as well as performance of EBMs in the field of LIS publications. The ethics and possible conflict of interests related to publishing in parent journals are discussed. The results of the study can be useful for revising journal policy or editorial board composition.
