The concept of Open Access (OA) is based on the principle that the findings of academic research should be openly accessible to the public. According to a survey by the Association of Research Libraries (ARL), from 1986 to 2002, journal expenditures of research libraries in the United States increased by 227%, while the number of journal titles purchased grew by only 9%, and the number of monographs purchased declined by 5%. Consequently, it is foreseeable that given the soaring journal subscription costs, libraries will struggle to sustain the resources required for research even if their budgets maintain the current average annual growth. The academic research resources supplied by libraries will decrease, which will subsequently impact the quality of teaching and research.
In response to the spirit of Open Access, initiatives such as Open Access Journals and Institutional Repositories are being actively promoted. An "Open Access Journal" refers to any peer-reviewed electronic journal that provides its contents free of charge to readers or institutions for accessing, downloading, copying, printing, sharing, distributing, or searching. On the other hand, an "Institutional Repository" is a system developed by academic and research institutions to archive their own research outputs, providing them to the public free of charge.
