Core journals are the main journals of a certain discipline, which refer to professional journals with large amount of professional information and high quality, which can represent the development level of professional disciplines and are valued by readers of this discipline.

The "core journals" are determined by the libraries of several universities in China according to the citation rate, reprint rate and abstract rate of journals. The accreditation standards of core journals are also formulated by some university libraries, and the evaluation and access standards of each school library are also different.

The press and publication management department has not participated in such selection activities. The General Administration of Press and Publication has never classified these periodicals according to their academic level. At the same time, there are many core journals, such as Nantah core, Peking University core, science and technology core, humanities and social sciences core and so on.

Extended data:

Academic journals mainly publish academic papers, while non-academic journals mainly publish documents, reports, speeches, experiences, knowledge, etc., which can only be used as materials for academic research, but not as articles of papers.

Because the selection of "General Introduction" is based on a large number of published, collected and cited articles, it does not emphasize the boundary between academic journals and non-academic journals, and naturally there is no strict distinction. ?

Specifically, the summary is academic and non-academic, mainly in two aspects, one is the nature of the journal, and the other is the purpose of the journal.
