Open Access Journal Index-OAJ

Open Access Journal Index (OAJ) is a high-quality open-access (OA) journal database jointly developed by the joint lab of the National Science Library, Chinese Academy of Sciences (NSLC), and China Educational Publications Import & Export Corporation (CEPIEC). OAJ is committed to addressing the needs of open science practices in China, adhering to international academic evaluation criteria. By combining peer review with data analysis, OAJ conducts comprehensive evaluation of applicant journals from multiple dimensions, including academic quality, publishing norms, open access, and research integrity. The goal of OAJ is to select high-quality fully OA journals across all disciplines worldwide.

Through its "application-review" access mechanism, OAJ now covers all disciplinary fields, including natural sciences, social sciences, and humanities, establishing an authoritative and inclusive open-access journal resources repository. As a key component of China's open science infrastructure, OAJ is committed to fostering an open, equitable, and high-quality academic exchange environment. It provides researchers, research management institutions, and the publishing community with a trusted reference for open-access journals, facilitating the global co-construction and sharing of academic resources.
