Abstract: What are the classifications of domestic periodicals? Broadly speaking, the classification of periodicals can be divided into informal periodicals and formal periodicals. The main purpose of periodical grading is to extract and highlight a few outstanding key periodicals from all periodicals, so there are generally not many grading levels, mostly 2-3 grades, and a few are above 4 grades. There are national periodicals, provincial periodicals, core periodicals and non-core periodicals, etc. Let's take a look at how the periodical level is divided. I. Classification methods of periodicals

1. Classification in a broad sense

In a broad sense, the classification of periodicals can be divided into informal periodicals and formal periodicals. Informal periodical refers to the periodical which is approved by the administrative department to receive the "approval of internal newspapers and periodicals" as an intra-industry communication (generally limited to intra-industry communication and not publicly released), but it is also a kind of legal periodical. Generally, formal periodicals have gone through the process of informal periodical. Official periodicals are examined and approved by the State Press and Publication Administration and the State Science and Technology Commission within the agreed amount, and incorporated into the "unified domestic serial number". The application for running periodicals is relatively strict, and it is necessary to have certain publishing strength. Official periodicals have independent publishing policies.

"domestic unified serial number" is the abbreviation of "domestic unified serial publication number", that is, "CN number", which is the code assigned to serial publications by the administrative department of press and publication. "International serial number" is the abbreviation of "international standard serial publication number", that is, "ISSN number", and most periodicals in China are equipped with "ISSN number".

China's legal periodicals are divided into official periodicals and informal periodicals:

1) Official periodicals

are examined and approved by the State Press and Publication Administration and relevant state ministries and commissions within the agreed amount, and are incorporated into the "unified domestic serial number". The official periodicals publicly issued at home and abroad have a unified domestic serial number (CN) and an international serial number (ISSN), which is the most basic symbol of the official periodicals publicly issued.

the standard format of cn serial number is: CNXX-XXXX/x,

CN is the country name code of China, the first two digits are the area code, the last four digits are the serial number of regional continuous publications, and the last letter is the classification number.

For example, the serial number of Reader magazine is CN62-1118/z, 62 is the regional code of Gansu Province, 1118 is its serial number, and z indicates that the magazine is a comprehensive publication. (The classification of periodicals is classified according to the basic categories of China Library Classification (4th Edition))

2) Informal periodicals

refer to the periodicals that have been approved by the administrative department to receive the "internal newspaper approval" as the internal communication of the industry, and may not be publicly issued.

2. Classification by discipline

Taking the Chinese Library Book Classification and Periodical Classification Table as the representative, periodicals are divided into five basic categories: (1) Marxism-Leninism, Mao Zedong Thought (2) Philosophy (3) Social Sciences (4) Comprehensive publications. In the basic categories, it is divided into several categories. For example, social science is divided into general social science, politics, military affairs, economy, culture, science, education, sports, language, writing, literature, art, history and geography.

3. Classification by content

Taking the news and publication volume of Encyclopedia of China as the representative, periodicals are divided into four categories: (1) general periodicals, which emphasize knowledge and interest and have a wide readership, such as People's Pictorial and Popular Movies in China, Time and Reader's Digest in the United States, etc. (2) Academic journals, which mainly publish academic papers, research reports, reviews and other articles, mainly targeting professional workers; (3) Industry periodicals, which mainly report the products, market conditions, management progress and trends of all walks of life, such as Motorcycle Information in China, Furniture, Office Equipment and Products in Japan, etc. (4) Search periodicals, such as National Newspaper Index in China, National New Bibliography, American Chemical Abstracts, etc.

4. Classification by academic status

It can be divided into core journals and non-core journals.

Core journals refer to authoritative journals that can best reflect the academic level of a certain discipline (or several fields), with a large amount of information and high utilization rate, and are widely valued.

The determination of core journals in China mainly uses bibliometrics and expert consultation.

Peking University Publishing House published the Outline of Chinese Core Journals in 1992, and published the second edition in 196. In the second edition, 1,578 core periodicals are selected from nearly 11,111 Chinese periodicals being published, and a brief introduction is made. On the basis of the second edition, the third edition was launched in 2111. Overview is an important reference book for us to understand the national core journals.

it is of great significance to know the core journals. 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 the reading level. For example, students majoring in language and literature should first read core periodicals such as China Language and Literature Review, instead of putting the cart before the horse. As far as the library is concerned, under the condition of limited funds, the core periodicals are of course the first choice when subscribing. As far as the scientific research management department is concerned, it can statistically analyze the papers published by units or individuals in core journals as an important indicator to measure their academic level. Therefore, people often take publishing articles in core journals as their pursuit goal.

Of course, core journals and non-core journals are not fixed. Non-core journals can rank among the core journals through hard work; Core journals will also be eliminated if they stand still.

II. Classification of Periodicals

There is no government department in the country to classify periodicals. The so-called periodical level is only an understanding of the periodical industry and some social organizations have launched periodical catalogues. Although there is no classification in the country, the professional title evaluation department has requirements for periodical level.

in the past, it was divided into first-class publications, second-class publications and third-class publications. At present, it is generally divided into two categories: "core journals and general journals", and in recent years, some places have been divided into core journals; Authority, importance and core.

1. Provincial Periodicals

"Provincial Periodicals" refer to periodicals sponsored by provinces, autonomous regions and municipalities directly under the Central Government and their subordinate ministries, commissions, departments and bureaus, as well as journals (periodicals) sponsored by various colleges and universities.

For example, the organizers of Shaanxi Education are: Shaanxi Provincial Department of Education

2. National periodicals

National periodicals refer to publications sponsored by national ministries, national organizations, organizations, institutions and academic institutions.

For example, the organizer of Modern Business: China National Business Information Center

3. Core Journals

At present, there are seven core journals (or source journals) selection systems in China, and all the journals in the catalogue of these source journals can be regarded as core journals.

"Chinese Core Periodical" of Peking University Library;

Nanjing University "Chinese Social Science Citation Index (CSSCI) Source Journals";

"Source Journals of China Science Citation Database (CSCD)" by the Literature and Information Center of Chinese Academy of Sciences;

"Statistical Source Journal of Sci-tech Papers in China" (also known as "China Sci-tech Core Journal") by China Institute of Science and Technology Information;

"China Core Journal of Humanities and Social Sciences" by the Literature Information Center of Chinese Academy of Social Sciences;

China Journal of Humanities and Social Sciences Society "Core Journal of China Journal of Humanities and Social Sciences";

wanfang data Co., Ltd. is building the "China Core Journals Selection Database".

At present, the core journals required by the professional title evaluation department are mainly "Chinese core journals" and "Chinese Social Science Citation Index (CSSCI) source journals". Very few evaluation units use "China Science Citation Database (CSCD) source journals".

III. Illegal publications

A publication published without the approval of the state press and publication administration department is an illegal publication, which specifically includes:

1. An illegal publication without a serial number;

2. Illegal publications with forged serial numbers;

3. Illegal publications with fraudulent serial numbers;

4. Illegal publications with overseas serial numbers;

5. Illegal publications that completely use the names and serial numbers of other publications.

Today, there are a lot of illegal periodicals. It is really not a simple matter to submit a manuscript, and it is not necessarily a good thing to receive a manuscript invitation. Maybe a trap is waiting for you. The simplest and most practical way to verify the truth is to visit the website of the State Press and Publication Administration or call the provincial press and publication authorities.

There are many magazines that directly advertise on the Internet, especially medical and educational magazines. Don't contribute to them, this kind of publication is generally fake, and you can know it by checking it on the website of the Press and Publication Administration. Now all the regular magazines don't worry about manuscripts.
