Since open access is a relatively new phenomenon for quite a few researchers, many of them have questions regarding the quality of open access publication channels, especially open access journals. Their doubts are reinforced by the phenomenon of the so-called "predatory journals". These are journals that publish articles in open access and charge high publishing costs or APCs, without, however, organizing decent editorial services and peer review. In other words, they take advantage of the open access model solely to make money. The articles concerned are not necessarily worthless; they can contain perfectly reliable research that has unfortunately been published in a predatory journal (the publications therefore do not count for funding and for career evaluation).
Fortunately, there are tips for recognizing "predatory journals". Below you can find a brief overview of the most important tips. To be completely sure, however, it is also advisable to consult the page with more general rules of thumb in which the tips below are included.
How do I choose a qualitative open access journal?
Check whether the journal is included in the Directory of Open Access Journals: Peer review guarantees the quality of scientific journals. All journals in the Directory of Open Access Journals (DOAJ) use a form of peer review and thus guarantee quality control on the content.
Check whether you know one of the editors of the journal and contact this person with the question whether he/she is effectively editor of the journal and whether the journal applies proper peer review.
Check whether you know one of the authors of recently published articles and ask him/her about experiences, especially regarding peer review.
Consult the website Think. Check. Submit, through which you can check with a simple checklist whether a journal or publisher is reliable.
