J-STAGE (Japan Science and Technology Information Aggregator, Electronic)

       日本科学技术信息集成系统（Japan Science and Technology Information Aggregator, Electronic，简称J-STAGE）由日本科学技术振兴机构（Japan Science and Technology Agency，简称JST）开发，收录了日本各科技学会出版的文献（文献多为英文，少数为日文），包括200多种电子期刊，多种会议录以及研究报告等。收录文献以学术研究类为主，涉及科学技术的各个领域，如数学、通讯与信息科学、综合、物理、自动化、化学与化工、地质、农业、地理、环境科学、电子和生物等。
       该数据库大部分内容可以免费浏览全文，有部分内容（通常是最新出版的内容）只提供题录和摘要信息，不提供免费浏览全文。

       In order to maintain and develop Japan\'s science and technology research at an international level, it is important to disseminate outstanding research and development results to the world instantaneously. To that end, it is important to digitize scholarly journals of academic societies and research papers currently published in paper form by user organizations and release them on the web.

       In order to support the information transmission function of user organizations, the “Japan Science and Technology Information Aggregator, Electronic” (J-STAGE), developed by Japan Science and Technology Agency (JST), has set up the hardware and software necessary for electronic journal publishing within JST to provide services 24 hours a day, 7 days a week. By taking advantage of this hardware and software, user organizations are able to digitize currently published journals of academic societies and research papers with ease and at low cost. Digitized documents can be accessed anywhere in the world with this system. This project also links up with the National Institute of Informatics (NII), the National Diet Library (NDL), and Japan Link Center (JaLC).
