Open access is a broad international movement aimed at providing free and open online access to academic information, such as scholarly publications and scientific data. Open access is a new academic publishing model different from traditional communication methods, allowing readers to obtain research literature free of charge, unlike the subscription model where readers can access through paid subscriptions (usually via libraries). Open access journals mean there are no financial, legal, or technical barriers to accessing them, which means anyone can read, download, copy, distribute, print, search, and look up information, or use it in any other way within educational or legal agreements.
