The expanding studies in transformation of scientific communication and practical aspects of open scientific content and scientific process dictate to identify the subject scope of open science studies. For the purpose of the study, 561 journal publications in the Library and Information Science category included in the Web of Science database were analyzed. As a result, 27 topics are specified, their contents are described, and the differences in subject orientation between “the classical” WoS, and the newer ESCI, are revealed. The transforming infrastructure of scientific communication, researchers’ adaptation to open science, and science serials’ publishing practice are in the focus of the selected publications. Most of them are based on global experience, though the national experience and EC and BRICS projects and initiatives are not overlooked.
