The term predatory publishers was coined by Jeffrey Beall, Librarian at the University of Colorado at Denver. He published a list of unserious publishers and journals online, commonly known as Beall's list. It has now been removed from the web, but others have taken on the task of trying to keep the list alive. The website Stop Predatory Journals is such an example. However, some have the view that the list was too broad in its assessment.
