Quaternary - Open Access and Article Processing Charge (APC)
All articles published in Quaternary (ISSN 2571-550X) are published in full open access. In order to provide free access to readers, and to cover the costs of peer review, copyediting, typesetting, long-term archiving, and journal management, MDPI uses article processing charges (APCs). At present, the APC for Quaternary is fully subsidized by MDPI, meaning there is no charge to authors or their institutions.
Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.Please note that for papers submitted after 30 June 2019 an APC of 1000 CHF applies. Partial waivers may be available upon request.
