MDPI has been a strong proponent of the open access publishing model right from the beginning. As one of the pioneering fully open access publishers, we firmly believe that unrestricted access to research findings forms the foundation for better transparency, efficiency, and quality control across all scientific disciplines.

In December 2022, we reached a significant milestone by surpassing one million articles published. That is one million articles freely available to all, to circulate and build upon!

Offering free and immediate access to scientific papers empowers scientists to examine, validate, replicate, and expand upon existing results. This not only helps prevent redundancy and optimizes how resources are used but also paves the way for innovative new approaches.

The International Open Access Week takes place from 23 to 29 October 2023, providing a unique opportunity to connect the global movement towards open sharing and open science with the progress of policy transformations at the local level.

Our goal, during Open Access Week as well as throughout the year, is to offer resources for educating people about the benefits of open access publishing. The MDPI Blog offers a wealth of information around open access and open science.

Promoting the values of accessibility, transparency, and collaboration

Open access publishing embodies the fundamental values of democratizing knowledge and fostering global accessibility. It aims to break down barriers that have traditionally limited access to scholarly work, ensuring that knowledge is available to all, regardless of their financial or institutional affiliations. 

Discounts are part of our commitment to ensuring there are diverse pathways to Open Access publishing for researchers worldwide. MDPI supports scientific communities in several different ways. 

One of the key strengths of open access publishing lies in its ability to facilitate interdisciplinary research. By removing paywalls and promoting the sharing of knowledge across disciplines, OA encourages collaboration and innovation. Researchers from diverse fields can access and build upon each other's work, fostering a holistic approach to addressing complex global challenges. 

Funders' policies are getting aligned with open science

Governments, institutions, and funding agencies have recognized the transformative potential of open access and have implemented policies to promote it. These policies often mandate that publicly funded research should be made openly accessible. Such initiatives have accelerated the growth of open access repositories and journals, reinforcing the commitment to open access principles. Check our spotlights on OA policies in the US, EU and China. 

Open access publishing is continually evolving, with innovative and community-driven models and technologies shaping its future. Initiatives like "Plan S" and "cOAlition S" promote the adoption of OA publishing from the national funders’ perspective by requiring grantees to publish their research openly. A new policy announced by the US administration last year requires that, as of January 2026, all US federally funded research be made freely and immediately available after publication. 

Additionally, preprint servers such as MDPI's Preprints.org, which allow researchers to share their findings before formal peer review, have gained popularity, enhancing the speed at which new knowledge is disseminated. The rise of blockchain technology is also being explored to ensure transparency and authenticity in scholarly publishing. 

For more than twenty years, open access scholarly publishing has been revolutionizing academia by promoting the values of accessibility, transparency, and collaboration. Its support for interdisciplinary research, evolving policies, and innovative practices all contribute to its growing influence in the global research community. As open access continues to expand, it holds the potential to democratize knowledge, advance science, and drive positive societal change. 

MDPI is proud to be a leader in the transition to open access.
