Abstract: Abstract This study focuses on journals that lead their Web of Science (WoS) subject category ranking when the usual 2-year window for the Journal Impact Factor (JIF2) is used as the ranking variable, and examines evidence that contradicts their top-ranked position in the context of their group. The source data were obtained from all 177 WoS subject categories in the Science Edition 2015 Journal Citation Reports (JCR). I compared journals in each WoS subject category with leaders in terms of JIF2, number of citable items and number of citations that contribute to the JIF2. Rankings were calculated with alternative metrics (for example, the Journal Impact Factor without self-citations and the eigenfactor), and the minimum reduction in the number of citations that would displace the top-ranked journal from its leading position was also calculated. In addition, the stability of rankings over time, the number of WoS subject categories in which journals are leaders, the publishers that own leading journals, and the percentages of research articles (as opposed to review articles) published in different journals were also studied. In general, leading journals are not necessarily the top-ranked in terms of citations received or the number of citable items they publish. In addition, most leaders maintained their position when other metrics were used instead the JIF2, although rankings based on the eigenfactor were at variance with this finding. The distribution of publishers was highly skewed, with a linear relationship between the cumulative number of publishers owning the top-ranked journal and the cumulative number of WoS subject categories. In only 85 subject categories (48%) the percentage of research articles (not reviews) in the number of citable items was greater than the mean percentage for the subject category. In 31 instances, leaders did not publish any research articles, but only reviews.
