Journals Covered by Leading Indexing Databases

At MDPI, we aim to expand coverage by the main academic databases Science Citation Index Expanded (SCIE) and Scopus to all journals. Eighty journals have been included in the Science Citation Index Expanded (SCIE) in the Web of Science by the end of 2020. Out of these titles, nine are due to receive a first Journal Impact Factor (JIF) in 2021. Furthermore, the biomed-related journals are full-text archived in PubMed Central (complying with NLM funding requirements) and with article abstracts to be found in PubMed/MEDLINE. All MDPI journals are archived long-term with the Swiss National Library and CLOCKSS.

All Content is Open Access and Free for Readers

Journals published by MDPI are fully open access: research articles, reviews or any other content on this platform is available to everyone free of charge. To be able to provide open access journals, we finance publication through article processing charges (APC); these are usually covered by the authors' institutes or research funding bodies.

MDPI Publication Ethics Statement

MDPI is a member of the Committee on Publication Ethics (COPE). MDPI takes the responsibility to enforce a rigorous peer-review together with strict ethical policies and standards to ensure to add high quality scientific works to the field of scholarly publication. Unfortunately, cases of plagiarism, data falsification, inappropriate authorship credit, and the like, do arise. MDPI takes such publishing ethics issues very seriously and our editors are trained to proceed in such cases with a zero tolerance policy. To verify the originality of content submitted to our journals, we use iThenticate to check submissions against previous publications.

MDPI is Committed to the UN Global Compact

MDPI is a member of the United Nations Global Compact to support corporate sustainability and 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 started in 1996 and led to the 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.

Mission and Values

As a pioneer of academic open access publishing, we serve the scientific community since 1996. Our aim is to foster scientific exchange in all forms, across all disciplines. See the following page for more information on our guiding principles.

Diversity, Equity and Inclusion

As a pioneer open access publisher, our mission is to make new research findings accessible to everyone. We are serving scholars from across the globe and from a variety of backgrounds. To deepen our understanding of the research communities that we serve, we aim to build journals that are just as diverse and inclusive. Only by valuing differences can we create an equitable and inclusive work environment and foster the openness that is key to our mission.

The daily exchange of ideas between the East and the West has been at the heart of MDPI's progress from day one. We understand that diversity does not end there. More needs to be done to bridge the gap between the global North and South—and to create equal opportunities for people without regard to race, color, sex, gender identity, sexual orientation, age, religion, country of origin, physical ability, or socio-economic status. There is no place for discrimination on the basis of any one of these characteristics.

MDPI adopts the principles of the Coalition for Diversity & Inclusion in Scholarly Communications (C4DISC) to support building equity, inclusion, diversity, and accessibility in scholarly communications. The Coalition is committed to creating and maintaining an environment that respects diverse traditions, heritages, and experiences. Our focus is on eliminating barriers to participation, extending equitable opportunities across all stakeholders, and ensuring that publishers' practices and policies promote equitable treatment and do not allow, condone, or result in discrimination.
