Periodicals are divided into regular periodicals and supplements. Regular periodicals are the main periodicals, and supplements are added supplements. Supplements are meaningless and not good enough. Theoretically speaking, the author's manuscript does not meet the employment criteria, but the research is of great significance, and it can be published in the form of supplement, which is actually a disguised page fee.

Special issue: In English, it is a special issue. Many internationally renowned magazines (such as IEEE Trans) do this. It can't be said that special issues are worse than regular ones. The purpose of the special issue is to discuss Huashan's sword for a hot research topic, so as to attract attention. Those who publish papers in specialized journals generally do better in this field.

China Computer News and domestic software journals all do this, and the effect is good, with an admission rate of about one tenth. The difference between a special issue and a general issue is that the period of publishing papers is shorter, mainly around a certain topic. Because it takes up publishing space, it can be regarded as the root.

Explain in detail:

Extra space or separate brochures for newspapers and periodicals on anniversary or when necessary. According to the regulations of the General Administration of Press and Publication, each legal periodical can be supplemented twice a year. The competent unit, organizer and serial number of the supplementary periodical are completely consistent with the publications published in the normal cycle, and cannot be called illegal or illegal publications.

The supplements of popular periodicals are generally used to publish picture books, anthologies or commemorative special issues. Academic journals usually arrange some manuscripts with a certain level in supplements that can't be published in periodicals with normal cycles, so the academic influence of supplements is weaker than that of periodicals with normal cycles. China Journal Network generally does not include supplementary articles, but the supplementary articles are compared with the main journals.

Although it is not an illegal publication, its quality is far from that of official publications. Therefore, many places do not recognize supplements, especially schools and institutions. Generally speaking, when evaluating titles below intermediate level, most supplements of provincial periodicals are not recognized. However, supplements of national journals or core journals are often downgraded, which is equivalent to provincial journals or general academic journals.
