In academic publishing, predatory publishing is an exploitative publishing business model that involves charging publication fees to authors without providing the editorial and publishing services associated with legitimate journals (open access or not).
The idea that they are "predatory" is based on the view that academics are tricked into publishing with them, though some authors may e aware that the journal is poor quality or even fraudulent.[a] [2][3] (Wikipedia, February 2017)
