Open Access (OA) is a publishing model that allows readers to access research outputs without financial, legal, or technical barriers. The goal is to maximize the dissemination of knowledge and research findings, enabling anyone with internet access to read, download, and share content. Open Access is often contrasted with traditional subscription-based models where access to research articles is limited to paid subscribers. OA comes in various forms, mainly categorized into 'Gold' Open Access, where articles are published in openly accessible journals, and 'Green' Open Access, where authors self-archive their work in repositories.
