The research analysed the publication data from the Web of Science spanning ten years from the year 2011 to 2020. The scrutiny of the open access friendliness was focused on two main aspects: the sharing of OA publications and the use of licenses in OA publications. The conclusions reveal that, among the total publications, 29.15% were disseminated through four OA routes (Green OA, Gold OA, Hybrid OA, and Bronze OA). The highest percentage (43.85%) of the OA publications fall under “Gold OA.” Out of a total of 13,066 (56.86%) articles, a legal license was applied for, with CC-BY being the preferred license. The study identifies JSS Academy of Higher Education and Research as the leader in open access friendliness, securing the first position with an OAF score of 68.46.
