The Article Processing Charge is FREE for international authors.
The AREJ stopped reviewing and publishing articles from 2015 (stopped after publishing volume 23, issue 5, year 2015) to 2019 (reactivated from volume 24, issue 1, year 2019) during ISIS occupying Mosul city for three years after the military liberation operation conducted by Iraqi forces to liberate Mosul city. The AREJ has been receiving and publishing articles since 2019.
Previously, the journal published articles in Arabic and English, but in 2023, the publishing was turned to English only with Arabic abstracts.
