Predatory journal is a term, coined by Jeffrey Beall, to describe publishers who are more concerned with profit than ethics. These journals are scams. They prey on unsuspecting researchers, often targeting third tier economic areas, and masquerade as legitimate publishers. Predatory journals usually promise rapid review and publication in a leading journal. However, the reality is that these journals often have little to no peer review or editorial contributions before publication, are not indexed in research databases, and cost thousands of dollars to publish with them. Many will not notify the authors of fees until after article acceptance. Some even charge fees at submission.
