Open Access Library (OA Library) is an online database, in which all articles come from top famous publishers and databases, which can meet the needs of scholars in various fields.

At the same time, those articles that have been reviewed or unpublished can be viewed online, providing opportunities for academic exchanges. Readers can use keywords in the Open Access Library (OA Library) to search and download complete articles in PDF format, without registering and paying any fees.

Open Access (OA) is an Internet-based mechanism for unrestricted access to peer-reviewed academic journals. Open access represents unrestricted access and unrestricted reuse, which is why it is important. Open access is gradually applied to papers, academic monographs and book chapters. It removes price barriers (subscription fees, pay-per-view) and licensing barriers (most copyright and licensing restrictions).

According to the research library association, "open access" is an alternative to the traditional subscription-based publishing model. In this way, through the new digital technology and network communication, anyone can get all kinds of documents, including peer-reviewed journal articles, references, technical reports, dissertations and other full-text information through the network in time, free of charge and without any restrictions, for scientific research, education and other activities.

In order to promote the wide dissemination of scientific information, exchange and publication of academic information, improve the utilization rate of scientific research and ensure the long-term preservation of scientific information. This is a new way of academic information exchange. When submitting works, the author does not expect to get a direct monetary return, but provides these works for public use on the public network.
