Article Processing Charges

Publication of an article with us requires payment of a non-refundable article processing charge in accordance with our Article Processing Charges listed for each journal under the journal menu.

In the event an article is accepted for publication, the author originally submitting the article intended for publication (whether for himself/herself or on behalf of a group of authors or an institution) will be invoiced for the applicable APC. Payments of APCs must be made in the period stipulated on our invoice. Payments must be made in full via our third-party payment service provider and in accordance with such provider’s terms of service. Payment by any other means is permitted only in our sole discretion.

You acknowledge and agree that payment of an APC does not guarantee publication of an article.
