SCI will update the database while updating the journal impact factors in June every year, involving the inclusion of new journals and the elimination of journals with poor quality. SCI papers can still be retrieved before the affiliated journals are eliminated. But after being eliminated by SCI, it will never be found again.

Excellent journals are constantly emerging, but the disadvantage is that the journals will be uneven, so some journals will face the risk of being eliminated every year, which will affect the retrieval results of papers. Generally not, subject to the query results.

SCI-journal kick means that the author contributes to a journal or SCI-journal, but the paper catches up with the update of the sci-journal list when it sees the journal. Journals are kicked out and papers no longer belong to SCI journals. Whether the papers published in this journal will be retrieved as one of the signature topics can mean that the papers published in SCI journals can be found in the database.

It can be seen that a paper included in SCI not only needs to be published in SCI journals, but also needs to be successfully included in the database. In other words, the papers you see may not be indexed until SCI indexing is completed. Whether a periodical can be indexed depends on the actual situation when it is changed from a SCI periodical to a non-SCI periodical.

Generally speaking, when SCI sees a journal kicked out, the paper may or may not be submitted for review again. If the paper is not submitted for review and approved by SCI, it will not be indexed. Journals were rejected because they did not meet the criteria of SCI database retrieval. If the paper is submitted for review, it may be retrieved, but the probability is relatively low. ?
