Predatory publishing, also write-only publishing or deceptive publishing, is an exploitative academic publishing business model that involves charging publication fees to authors while only superficially checking articles for quality and legitimacy, and without providing editorial and publishing services that legitimate academic journals provide, whether open access or not. The rejection rate of predatory journals is low, but seldom zero. The phenomenon of "open access predatory publishers" was first noticed by Jeffrey Beall, when he described "publishers that are ready to publish any article for payment". However, criticisms about the label "predatory" have been raised. A lengthy review of the controversy started by Beall appears in The Journal of Academic Librarianship.

An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. They serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They nearly universally require peer review for research articles or other scrutiny from contemporaries competent and established in their respective fields.
