The review period of open source journals is usually shorter than that of traditional journals, because open source journals are usually published only on the Internet, and there is no paper version, so they are not limited by the layout. In addition, each open source SCI journal has its own operating entity and business strategy, and also has its own rules and regulations on the review arrangement. Although the review process of SCI papers is similar, the review cycle is long and short because of the journal itself and the quality of the papers.
