ISSN, also known as the international serial publication number. Is formulated by the international organization for standardization. It is the identification number of international journals.
The periodical identification number approved by the General Administration of Press and Publication. At present, the periodical query window of the General Administration of Press and Publication can query the serial number information. CN serial number is a legal passport for the publication and distribution of periodicals in China.
Journals without a CN number are illegal in China. If foreign periodicals want to be published in China, they must first obtain the CN number. Therefore, the CN serial number is equivalent to the legal certificate of the periodical.

The determination of core periodicals in China mainly adopts bibliometrics and expert consultation.
Peking University Publishing House 1992 published the Outline of Chinese Core Journals, and 1996 published the second edition. The second edition selects 1578 core periodicals from nearly 10,000 Chinese periodicals being published, and makes a brief introduction. On the basis of the second edition, the third edition was launched in 2000. Overview is an important reference book for us to understand the national core periodicals.
Understanding the core journals is of great significance. As far as editors are concerned, they can learn from core journals. As far as readers are concerned, establishing the consciousness of core periodicals can clarify the value orientation and improve their reading level.
For example, students majoring in language and literature should first read core journals such as China Language and Literature Review, instead of putting the cart before the horse. As far as libraries are concerned, core periodicals are of course the first choice for subscription under the limited funds.
As far as scientific research management departments are concerned, statistical analysis can be made on the papers published by units or individuals in core journals as an important indicator to measure their academic level. Therefore, people often aim at publishing articles in core journals.
