View AbstractThis article examines the factors driving the adoption of Open Access (OA) scholarly communication and the persistent challenges that hinder its universal adoption. Using a narrative review methodology, relevant academic literature was retrieved from databases such as Google Scholar, Web of Science, and Scopus, and analyzed to explore the evolution of diverse OA publishing models, and role of institutional policies, technological advancements, and researchers’ motivations in promoting OA adoption. Based on the review, three key themes and eleven sub-themes were identified. Findings reveal that OA scholarly communication democratizes access to knowledge by enhancing research visibility and fostering collaboration. However, significant challenges persist, such as the financial burden of Article Processing Charges, the proliferation of predatory journals, and resistance from stakeholder’s dependent on subscription revenues. The review also highlights policy-level interventions, including Plan S and transformative agreements, as effective in addressing some barriers. The article concludes that while OA has immense potential to transform scholarly communication, achieving its full benefits requires overcoming financial, quality, and policy standardization challenges to ensure equitable global access to knowledge.
