As scientists we live in a “publish or perish” era which leaded to the explosion of traditional and modern instruments of scientific communication, including the so called “predatory” open access journals. I wrote down a short list including some of the potential characteristics of predatory journals in the field of biomedical sciences, but I feel my list is incomplete or maybe incorrect.
1. They use bombing authors with e-mails inviting for articles of any type (original articles, reviews, case reports, commentaries etc.), often addressed to a coauthor rather than the author himself. Invitations from non-predatory journals are generally for a specific topic and a specific type of article.
2. They publish low quality articles, often written in poor English and with low originality or methodological value, mixed with better or even excellent research articles.
3. They often report an impact factor (IF) calculated by themselves, but not officially attributed to the journal. Nevertheless, predatory journals with a high officially gained IF may exist.
4. They have not a standard number or a limit for the articles to publish in a single issue.
5. They have not clear peer review policies and no information about article rejection rates.
Do you have any other suggestions?
