1, website query.
When the article is an SCI article, we can log on to the web of science website for query. If it can be found, it proves that the article belongs to SCI. Web of Science is the most commonly used method to search articles included in SCI, but this website can only be used if members log in. However, most schools or libraries have purchased website resources, and relevant personnel can consult the school library.
2. Check regularly.
If the article is SCI, it means that the article has been published in SCI journals. As long as you query whether the journal in which the article is published is a SCI journal, you can judge that the article is SCI. In addition, the SCI periodical catalogue will be updated regularly. Every update will add new periodicals and kick out some original periodicals. Therefore, when checking whether the journal is an SCI journal, we should also pay attention to the time when the article was published.
It should also be reminded that sometimes an article published in SCI journal can be retrieved on SCI, but this article can't be retrieved, so that article is only online and can't be retrieved on the scientific Web.
At this time, strictly speaking, this SCI paper has not been published in SCI journals. However, it can also be indirectly proved that SCI papers are not online through the retrieval certificate that this journal is a SCI journal and the acceptance certificate of this paper.
In fact, SCI papers are not only in English, but also some Chinese periodicals and documents in Korean, Russian, German and French can be found on the Web of Science, but most famous periodicals are of course in English.
If an article is published in a new journal, generally speaking, if it is a well-known publishing house, such as Wiley, ACS, RSC and IEEE, even if the journal was not included in SCI when it was first published, it will be included sooner or later.
However, it is hard to say that a publishing house is impartial. Therefore, if you want to read SCI papers, you can choose journals owned by well-known publishing houses when choosing journals.
