Publishing Format

All articles published by MDPI are made immediately available online under an open access license. This means that:

  • Everyone has free and unlimited access to the full text of all articles published in MDPI journals;

  • Everyone is free to re-use the published material if proper accreditation/citation of the original publication is given;

  • Open access publication is supported by the authors’ institutes or research funding agencies by payment of a comparatively low Article Processing Charge (APC) for accepted articles.


MDPI was launched in 1996 as a non-profit institute for the promotion and preservation of the diversity of chemical compounds. Founded in Basel, Switzerland, as a “Verein” under Swiss law, the abbreviation MDPI initially stood for “Molecular Diversity Preservation International”. After successfully running several open access journals, including Molecules, Sensors and Entropy, MDPI developed into a leading open access publisher, and the publishing part was transferred into a separate legal entity in 2010. MDPI remained as the abbreviation of the newly founded “Multidisciplinary Digital Publishing Institute”. The samples project continues today and is maintained by the MDPI Sustainability Foundation. MDPI has hosted or organized a number of scientific conferences, including electronic (virtual) conferences. The timeline below summarizes major milestones in each year since the establishment of MDPI.

International Cooperation

United Nations Global Compact

MDPI is a member of the United Nations Global Compact to support corporate sustainability, and we have committed ourselves to the ten principles associated with the Compact.

Sustainability has always been at the core of MDPI’s values, starting with the collection and preservation of rare chemical samples that began in 1996 and led to our first journal, Molecules. Sustainability has become one of our flagship journals, and we have supported and organized several conferences and events based on sustainability, including the 6th World Sustainability Forum. As a global enterprise, we see it as our duty to promote responsible practices that will ensure a bright future for our planet.


Obtaining high-quality review reports is critical for any journal’s editorial process. At MDPI, we have put in place several measures to motivate reviewers and reward them for their work. We are proud of the quality of reviewer reports we receive and grateful for the hours put in by active researchers from across the globe.

Reviewers of MDPI’s largest journals can get recognition via Publons, a website dedicated to rewarding peer reviewers. Publons has now taken this one step further and launched the Publons Reviewer Academy to help train reviewers to provide useful feedback. Through the Academy, researchers can be trained and tutored in various aspects of how to provide structured feedback that will be of genuine help to editors and authors. We support this initiative and recommend it to potential MDPI reviewers, especially early career researchers. See the Publons announcement for further information.

More information on reviewing for MDPI, including how to volunteer as a reviewer, can be found here.

Institutional Open Access Program (IOAP)

MDPI is dedicated to providing free access to the latest research. To cover the costs of publishing open access, authors are billed an article processing charge (APC) for each accepted paper. Some institutions may find that their affiliated authors regularly publish in MDPI journals, and that administering an increasing number of APCs can be time-consuming. Our open access program aims to support institutions through various means.
