What is the core periodical in Peking University?
The core of Peking University is determined by the library of Peking University, in conjunction with many authoritative experts in academic circles, after appraising the libraries of several universities in China according to the citation rate, reprint rate and abstract rate of periodicals. It has been widely recognized by academic circles that the standards for identifying core journals are also formulated by some university libraries, and the evaluation and access standards of each school library are also different.
Introduction to the core of Peking University:
The core of Peking University is the academic definition of a certain kind of periodical, a classification of periodical grades. Its target is academic journals in China. It is a periodical divided according to various factors such as periodical influence factors. The core of Peking University is determined by the library of Peking University, in conjunction with many authoritative experts in academic circles, after appraising the libraries of several universities in China according to the citation rate, reprint rate and abstract rate of periodicals. The accreditation standards of core journals are also formulated by some university libraries, and the evaluation and access standards of each school library are different, which has been widely recognized by the academic community [1]. In terms of influence, its level is one of the more authoritative categories. It is the most authoritative academic influence besides NTU core and China Science Citation Database (cscd). Also known as "China Core (PKU)".
An Overview of Chinese Core Journals is a research project in which many periodical workers and experts from relevant units from Peking University Library and more than a dozen university libraries in Beijing participate. The research results of this project are published as printed books. Previously, Peking University Publishing House published nine editions: 1992 (first edition), 1996 (second edition), 2000 edition and 2004 edition. The 20 1 1 edition, 20 14 edition, 20 17 edition and 2020 edition, as well as various versions of the China Core Journals, which are popular on the Internet, were not published by this project team. The first five editions of the core journals of Peking University are updated every four years, and every three years from 2008, and the book Catalogue of Core Journals of Peking University is published. This book provides a theoretical reference for the evaluation of professional titles in colleges and universities nationwide.

What are the core journals of statistical sources?
The full name of "Statistical Source Periodicals" is "Statistical Source Periodicals of China Sci-tech Papers" (also known as China Sci-tech Core Periodicals), and the catalogue of statistical source periodicals will appear in the Citation Report of China Sci-tech Journals published once a year by China Institute of Sci-tech Information. Entrusted by the Ministry of Science and Technology, China Institute of Sci-tech Information (ISTIC) began to make a statistical analysis of the number of papers published and cited by China's scientific and technological personnel at home and abroad from 1987, and established the China Sci-tech Papers and Citations Database (CSTPCD) by using the statistical data, which has been widely concerned and praised by all walks of life. Statistical source periodicals of China scientific papers are the data sources of CSTPCD. The academic quality of journals is evaluated by the Comprehensive Index Evaluation System of China Sci-tech Journals, and the scope of journals included in China Sci-tech Journals Network is adjusted every year.
China Institute of Sci-tech Information issues inclusion certificates to journals that have passed the comprehensive evaluation of multiple academic indicators twice every April or June 5438+ 10, and China Institute of Sci-tech Information holds a press conference on the statistical results of China's sci-tech papers to the media at the end of each year (June 5438+065438+February).
China Journal of Statistical Sources of Sci-tech Papers is not a lifelong system, and its validity period is three years. After three years, China Institute of Science and Technology Information will re-evaluate it and follow the principle of "survival of the fittest". Therefore, the academic influence of "statistical source journals" is increasingly accepted by academic institutions and scientific research institutions, and is regarded as one of the evaluation indicators of the academic level of scientific research papers.
Both statistical source journals and core journals can reflect journals closely related to a certain specialty, but they are different in concept and content. The former includes social (humanities) science and natural science, and adopts the method of multi-index comprehensive screening to formulate the ranking table of core journals. The latter only includes natural sciences, and multiple indicators are selected for comprehensive screening according to literature citation data, and then the ranking order is listed according to the citation of periodical papers. Both of them provide readers with some periodicals with great reference value in different ways and angles, and provide important reference basis for units and individuals to order, collect, read, contribute and choose periodicals. Core journals cover a large number of journals and have a wide readership, but they contain fewer biological and medical journals than the source journals, and there is a certain time lag due to the publication of 1 times in four years, so they cannot fully reflect the journals of that year. Source journals include more biological and medical journals. Because it is published 1 time a year, it can objectively reflect the current situation of periodicals.
