So what does CN periodical mean? CN periodical refers to a periodical with a unified domestic serial number, that is, the CN serial number. This needs to find the CN number filed by the General Administration of Press and Publication before it can be standardized. A CN periodical must have both a CN serial number and an ISSN serial number, which is considered as a regular CN periodical.
Introduction to CN periodicals: CN periodicals refer to publications registered in China and publicly distributed in China. The serial numbers of these publications are all marked with the letter CN, and people are used to calling them CN publications. It is worth noting that CN periodicals are the only standard for identifying the authenticity of periodicals in China at present. That is, all periodicals officially approved by the State Press and Publication Administration must have CN serial numbers.
A formal publication generally has two serial numbers, one is ISSN, also called international serial number, and the other is CN serial number, also called domestic standard serial number. International serial numbers are not difficult to achieve, because magazines are loosely managed abroad, and registering a magazine is as simple as registering a company.
However, the CN number is different. In China, the management of magazine registration is very strict. Private people are not allowed to run magazines, and neither are enterprises. Only state organs and institutions should register with the press and publication bureau and accept the annual review. All publications registered with the Press and Publication Bureau have CN numbers.
This is the most important thing for most professional titles and colleges, otherwise it will be regarded as a local publication or an internal publication and cannot be regarded as an academic achievement.
