Contribution of Iranian Scholars to Predatory Journals

To find how and to what extent Iranian scholars contribute to predatory journals.
The scientometircs approach is employed. Jefery Beall's List of Predatory journals was adopted. As of January 2016 the number of predatory journals in the list was 910, all of which were studied.
649 Iranian scholars are contributing to 276 predatory journals. Most of them are professors and 35% of all are affiliated to Iran Ministry of Science, Research and Technology. Regarding their field of study, the highest number of researchers were in medical sciences (17%) and the lowest in art. The most predatory journals having Iranian contributors belong to Asia.
An upward trend is seen in the contribution of Iranian scholars to predatory journals. Such journals should be identified, listed and introduced to universities and organizations regularly and being emphasized in different ways as an important matter. This way researchers would be informed and less interested to join predatory journals.
