When choosing SCI journals to publish articles, whether to choose open access (OA) journals is a problem that needs to be decided according to the author's own actual situation. This involves the cost of publishing SCI and the popularity of the paper.

OA journals are open source journals, which charge authors, but readers can get and download papers for free. In this mode, although the author needs to spend money to contribute, it usually has a high acceptance rate and citation rate, and the popularity of the paper is also high. For authors who want to spread research results and improve their academic influence through papers, choosing OA journals may be a good choice.

Non-OA journals charge readers, and the author's articles can be downloaded and viewed for free. In this mode, the author does not need to spend extra money to publish the paper, but for some readers, it may be necessary to pay to read the whole content of the paper.

The difference between open access periodicals and non-open access periodicals

The biggest difference between OA journals and non-OA journals is the difference in publishing profit model. OA journals charge authors, while non-OA journals charge readers.

Open access journals are also open source journals. Open source journals are academic journals that readers can obtain for free through the Internet, without economic, legal and technical restrictions. Any peer-reviewed electronic journal that provides readers or institutions with free access, downloading, copying, printing, publishing or retrieving articles is called an open source journal.

"Open Access" Publishing Mode: Contribution of Scientists (generally requires peer review fee)->; "open access" journals (peer review, peer review)->; Network communication->; Readers (free). Non-open access journals are also non-open source journals. This is the traditional publishing mode.

Traditional publishing mode: contribution by scientists (generally no peer review fee is paid)->; Academic journals (peer review, peer review)->; Publishing, printing and channels-> Readers (subscription)

In the traditional publishing mode, publishers pay the costs of "peer review, organization of peer review" and "publishing, printing and channel" by selling readers' subscription fees, and publishers can make profits in this process. In the "open access" publishing mode, the "open access" journals charge scientists peer review fees, and at the same time accept state and private funds to maintain the "peer review" costs and maintain the network platform, which is completely free for readers.

To sum up, OA journals do not represent water journals or early warning journals. And non-OA journals do not necessarily mean good. Non-OA journals will also have some water journals. There are even some blacklisted early warning journals. But in the eyes of many authors, OA journals have a bad reputation. This is because OA journals contain some predatory journals. Their official website is rough. The standard for accepting papers is very low. Publish the paper to such a SCI journal. It must be a great harm to the author.

Therefore, before publishing SCI papers, you should have a good understanding of the journals you want to publish. You can consult your tutor and seniors. You can also go to the list of early warning journals of Chinese Academy of Sciences. It can't be simple, because this journal is an open source journal, so it will be completely denied. It is still necessary to judge from the particularity, directionality and many aspects of the influencing factors of zoning.
