Article Processing Charges

To fund the journals, ISJ charges an article processing charge to be paid by the author or the author's institution. This model allows ISJ to make all articles available to the public for free immediately upon publication. ISJ article processing charges vary by journal but on average are lower than most open access publishers. Depending on circumstances, ISJ may reduce the fee for authors from developing countries. Kindly visit the ‘About Us’ page for specific information about the article processing charges of the journal you intend to publish your article.

Authors are required to pay a fair manuscript handling fee for the processing of their articles.  However, there are no submission charges. Authors are required to make payment only after their manuscripts have been reviewed and accepted for publication. The exact amount of article processing charges (APCs) for each journal is given below.

To subscribe for an article published by any of our journals, kindly contact The subscription rate is $300 and it is the same for all countries. All journals are open access and subscribers shall receive the print edition.
