American universities have a lot of independent professional libraries, but they lack English documents that systematically introduce China’s academic progress; on these ground, “China boutique bilingual academic journals database” will enable China’s academic journals to enter more professional academic circles, bringing China’s academic to the world.

China has always been committed to providing college teachers and students with low-cost, high-quality resources and various value-added services; it is undeniable that the readers’ dependence on CNKI is ever increasing. Driven by the market demand, the library's resource construction has changed quietly, and the “journal-network integration” proposed by CNKI has catered to the trend and characteristics of the development and change of resource construction. We have a positive attitude towards this exploration and change of CNKI. We hope that the journal circle can work with CNKI to provide us with better products, better services and better platform.
