This study explores the publishing success of less experienced researchers including early career researchers in a selection of library and information science journals. The study includes all authors of articles and reviews published in 10 library and information science journals during a 20-year period (2001–2020). The prior publication of each author is determined at the time of publication in one of the ten journals. The analysis includes 14,612 publications and publication histories of 36,417 authors. The results show that there are considerable differences between journals, and that the share of publications by less experienced researchers has generally decreased over time. Library automation journals publish considerably more publications by early career researchers than information science journals do. Publications in these 10 library and information science journals are being published by authors with an increasing publishing experience and fewer papers are being published by author teams with little experience.
