Core journals briefly introduction-what are SCI, SSCI, CCSCI, CSCD, science and technology core (statistics source journals), and Peking University core journals? SCI, SSCI, CSCCD, and CSCD were internationally recognized guidelines for scientific journals. They were important standards to measure the quality and impact factor of journals.

The quality and impact factors of these journals were also highly recognized internationally. Peking University's core journals referred to the academic journals in the library of Peking University that were recognized by the China Association for Science and Technology as having a high academic level and influence. Peking University's core journals included Science in China, Biology in China, Science and Technology Information in China, Progress in Mathematical Sciences, Geophysical Sciences, Earth Chemistry, Astronomical Sciences, Astronomical Sciences, Atmospheric Sciences, Science and Technology Information, Progress in Electronic Sciences, and so on.
