Popis: The goal of this study was to investigate the dynamics of two journals indicators (Cited Half-life and Citing Half-life) in the case of incomplete or inaccuracy data in the Journal Citation Reports. A detailed analysis of these data for the CdHL and CgHL indicators for 1997–2018 was performed. The previously formulated similarity hypothesis on journal distribution by half-life period was clarified. Methods for determining the weighted average values of half-life indicators were developed in detail. The test of the similarity hypothesis had identified the time frame within which its objectivity was certain. Results of our study revealed that the dynamics of half-life indicators were positive; moreover, and these dynamics are much more pronounced for permanently retentive journals, i.e., journals that were present in the JCR during the entire 22-year study period.
