MDPI Insights: The CEO's Letter #7 - Nobel Laureates Entrust MDPI with Their Research

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Nobel Prize Laureates Entrust MDPI with Their Research
The Nobel Prize stands as a hallmark of distinction, honouring ground-breaking research across disciplines. Annually, the Nobel Prizes are awarded in six categories: Physics, Chemistry, Medicine or Physiology, Literature, Peace, and Economic Sciences.
Through the years, renowned scholars have entrusted MDPI with their work. As at December 2023, 26 Nobel laureates have contributed to more than 75 articles across 25 MDPI journals, including: Antibiotics, Applied Sciences, Biology, Biomedicines, Cancers, Catalysts, Cells, Crystals, Entropy, Games, IJMS, Life, Materials, Micromachines, Molecules, Pharmaceuticals, Pharmaceutics, Photonics, Quantum Beam Science, Remote Sensing, Sensors, Solids, Universe, Vaccines, and Viruses.
The best of the best trust us with their work.
Nobel Prize Laureates Who Have Published with MDPI
We are proud to list the names of Pierre Agostini, Hiroshi Amano, Werner Arber, Aaron Ciechanover, Robert H. Grubbs, Oliver Hart, Gerard ‘t Hooft, Michael Houghton, Harald zur Hausen, Katalin Karikó, Jean-Marie Lehn, Gérard Mourou, Ferid Murad, Shuji Nakamura, William Nordhaus, Kostya S. Novoselov, Giorgio Parisi, Charles M. Rice, Alvin E. Roth, Donna Strickland, K. Barry Sharpless, George F. Smoot, Anne L’Huillier, Drew Weissman, Kurt Wüthrich, Ada Yonath.
The privilege of hosting such contributors resonates deeply with our editorial teams. For instance, in this interview, the Editor-in-Chief (EiC) of Universe speaks on the significance of publishing a paper by Nobel laureate Gerard ’t Hooft within the journal.
2023 Nobel Prize Winners Published by MDPI
Nobel Prize Winners, 2023: Katalin Karikó, Drew Weissman, Anne L’Huillier (Ill. Niklas Elmehed © Nobel Prize Outreach)
Three laureates from the 2023 Nobel Prize cohort have trusted MDPI as their publishing platform. Notably, in a 2022 Pharmaceutics paper, molecular biologist Katalin Karikó and her team presented a methodology for evaluating mRNA capping efficiency, pivotal for therapeutic applications. Pharmaceutics had previously dedicated a Special Issue to “mRNA Therapeutics: A Themed Issue in Honor of Professor Katalin Karikó”, spotlighting ten articles from August 2021 to February 2022.
In the journal Vaccines, Professor Drew Weissman, collaborating with scholars from Pennsylvania University and George Mason University, contributed an influential review titled “Nanomaterial Delivery Systems for mRNA Vaccines”. His collaborative efforts spanned five papers across MDPI journals between 2021 and 2023.
Furthermore, Anne L'Huillier of Lund University, only the fifth female recipient of the Physics Prize, co-authored an article in Applied Sciences focusing on "Advanced EUV and X-Ray Optics". Similarly, Pierre Agostini, an Emeritus Professor from Ohio State University, co-authored an article featured in the special issue "Attosecond Science and Technology: Principles and Applications".
We extend heartfelt congratulations to all Nobel Prize laureates and express sincere gratitude for their confidence in MDPI as a platform for their scholarly contributions.

Impactful Research
MDPI Journals Newly Indexed in 2023
The aim of indexing is to enhance the quality and credibility of published research, ensuring that researchers access the most credible resources available. While the principle behind citation indexing is straightforward, it remains one of the most dependable methods for tracking an idea's evolution across various scientific disciplines.
Throughout the year, MDPI works to expand the reach of our publications across premier multidisciplinary databases like Web of Science, Scopus, EBSCO, and ProQuest. This initiative is spearheaded by MDPI's Indexing team, under the leadership of Dr. Constanze Schelhorn.
In 2023, MDPI achieved 54 new acceptances in Scopus, 29 in Web of Science, 52 in EBSCO, and 83 in DOAJ: Directory of Open Access Journals.
The team prioritizes ensuring that our journals feature in numerous specialized databases, including PMC, PubMed, MEDLINE, Inspec, CAS, and FSTA, among others. Currently, MDPI collaborates with over 65 renowned international databases, consistently enhancing our database affiliations annually.
MDPI’s journals are indexed in all major global databases.
Furthermore, we collaborate with universities and government organizations to list our journals in country-specific ranking lists and relevant institutional repositories. This ensures compliance with requirements often set by funders or institutions for authors to publish in specific journals.
Web of Science Adds 24 MDPI Journals to Emerging Sources Citation Index (ESCI)
Clarivate recently analysed MDPI’s new journals, resulting in 24 journals, mainly established in 2020, being added to the ESCI in November and December 2023. Additionally, five journals passed this assessment earlier in the year. For a complete list of our journals in Web of Science, refer here. Journals in the ESCI meet 24 quality criteria, ensuring editorial rigor. They may be considered for inclusion in broader indices like the Science Citation Index Expanded (SCIE), the Social Sciences Citation Index (SSCI), or the Arts and Humanities Citation Index (AHCI), based on four impact criteria.

Inside MDPI
MDPI Appoints New Chief Operating Officer (COO)
Alistair Freeland returned to MDPI and assumed the role of Chief Operating Officer in November 2023, a position he previously held from 2013 to 2019. He succeeds Dr. Yu Lin, who will remain a member of MDPI’s Board of Directors, overseeing significant financial decisions for the company. I would like to express my sincere thanks to Dr. Yu Lin for his service as COO.
Alistair brings extensive experience not only in scholarly publishing but also in technology and business management. Prior to rejoining MDPI, he was associated with SIX Group, the entity responsible for Switzerland's financial market infrastructure. There, he played a pivotal role in developing the blockchain-based platform SDX (SIX Digital Exchange), which has gained traction among major Swiss banks and the Swiss National Bank.
As COO, Alistair will collaborate with the MDPI management team to improve the practices and services we offer to scholarly communities. I am pleased to welcome Alistair back to MDPI and look forward to his contributions going forward.

As we approach 2024, I reflect on the incredible journey we’ve had together at MDPI this year. The past 12 months have been marked by ambitious projects and initiatives to improve our internal processes, and a commitment to continue delivering top-notch services to our stakeholders. I’d like to thank each and every one of our staff members for contributing to the positive experiences our stakeholders have reported in our surveys. Your dedication to speed, efficiency, and effective communication with our stakeholders is very much recognized and appreciated.
Becoming a stronger organisation
While we have encountered challenges in 2023, it’s important to understand that these are a part of our growth process. Difficulties provide us with opportunities to reflect, address problems at their roots, and ultimately evolve into a stronger organization.

I am deeply grateful to Dr. Lin for entrusting me with the role of CEO of MDPI. Looking forward, I am committed to working closely with our management team to lead MDPI and take it to a new level of excellence, aiming to establish it as the most trusted publisher in open access worldwide. This is a collective endeavour, with each of us shaping MDPI’s reputation. I therefore encourage us to take pride in our work, as it represents not only our craft but also MDPI as a whole.
Accountability and communication
As we look forward to 2024, there’s a lot to be excited about. Together, we’ll navigate challenges, seize growth opportunities, and refine our practices. To solidify MDPI’s position as the premier open access publisher globally, we must bolster accountability, improve stakeholder communication, share MDPI’s best practices, champion the open access philosophy, and educate stakeholders about our mission, methodologies, and motivations.

Obituary— Prof. Ralph Kenna
It is with deep sorrow that we announce the passing of our esteemed Editorial Board Member in Entropy, Prof. Ralph Kenna, who left us in October 2023. His contributions to our journal were invaluable, and his legacy will be preserved within Entropy. His absence leaves a void that will be deeply felt by all those who had the privilege of working with him.
Prof. Kenna was an Irish mathematician and theoretical physicist who was born in Athlone (Ireland). He was the head of the research group Statistical Physics of Complex Systems at Coventry University, which participated in prestigious European projects and collaborative initiatives. Prof. Kenna had very diverse interests ranging from statistical physics (especially phase transitions and critical phenomena) and complex systems to Irish mythology. An imaginative and enthusiastic researcher, of inspiration for his collaborators and students.
Prof. Kenna joined the Editorial Board of the Section “Statistical Physics” in 2020, bringing with him a wealth of knowledge and expertise in his field. In the same year, he edited a Special Issue titled “Phase Transitions and Emergent Phenomena: How Change Emerges through Basic Probability Models”, which garnered significant attention from the scientific community.
Throughout his tenure as Editorial Board Member, Prof. Kenna worked closely with the other editorial members and staff and played an instrumental role in the day-to-day operations of our journal. His loss is deeply felt by all of us at Entropy, and we extend our heartfelt condolences to his family, friends, and colleagues during this difficult time.

MDPI Insights: The CEO's Letter #6 - MDPI Spain Summit and ResearchGate

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
MDPI Spain Summit
Stefan Tochev (CEO, MDPI) gives the opening speech at the MDPI Spain Summit.
On Friday 10 November 2023 I was in Barcelona, Spain, to deliver the opening presentation and participate in a panel at MDPI’s Spain Summit, a two-day event, inspired by our salon events in China.
With 16 Editors-in-Chief (EiCs) and 20 Editorial Board Members (EBMs) in attendance, the event, organized by our conference team and Barcelona office, featured presentations on open access (OA), MDPI, and publishing market trends in Spain.
The event provided a great opportunity to engage with stakeholders from various MDPI journals, including Nutrients, Vaccines, Buildings, IJMS, and others. We were able to gather feedback and have open conversations around manuscript quality, the peer-review process, and journal development, as well as accreditation agencies.
The main objective of this Summit was to bring together Editors representing MDPI journals across various disciplines within Spanish universities and research centers, primarily from the Barcelona area. The aim was to facilitate an open and fruitful discussion regarding the development of their journals, the future of OA in Spain, and to provide meaningful interactions and networking opportunities.
Connecting with Editorial Board Members
Stefan Tochev in conversation with Summit participants: "Our EBMs are passionate about the journals they serve."
Interacting with our EBMs in person provides a valuable opportunity to show how important it is to us to connect with them, hear their perspectives on their journals and learn more about their own experience collaborating with MDPI.
From my conversations, it was clear that our EBMs are passionate about the journals they serve. I know the advice they provide may sometimes involve just small tweaks, but these can lead to important improvements. As the saying goes, small hinges swing open big doors.
As at November 2023, MDPI has over 6,300 EBMs affiliated with Spanish institutions, with more than 30 of them serving as EiCs or section EiCs. Furthermore, over 68,000 Spanish scholars have contributed as reviewers in MDPI journals.
Open Access in Spain
In 2023, Spain implemented legislation mandating immediate OA for all publicly funded research, aligning with the EU’s Plan S initiative to expedite the transition to OA. The Spanish government also approved a four-year, €23.8 million annual budget for the first national OA strategy, aiming to make publicly funded research freely accessible upon publication. This strategy aims to strengthen the quality and transparency of research in Spain, and to help promote movement towards a digital, low-carbon economy.
For further details of Spain's OA policy and the history of government mandates, click here.
Spain has already seen a notable decline in subscription-only articles, decreasing by 62% over a 10-year period, while gold OA increased by 42%. Green OA slightly decreased, suggesting a shift towards publishing in gold OA journals rather than traditional subscription-based ones. Here are some statistics from Scopus.
A big thank-you to the various MDPI teams, including our conference team and the Barcelona office, for organizing this very successful event!
MDPI colleagues from various offices gathered to host and support the first MDPI Spain Summit, in Barcelona, Spain.
I think this type of gathering has the potential to become an annual event in various locations. For example, Manchester could be an option, as we have over 30 EiCs and over 3,000 EBMs in the UK, a top market for MDPI that publishes high-quality research.

Corporate Marketing and Communications Strategy Session
Members of MDPI’s Corporate Marketing & Communications team.
For the past few years, I have led the Corporate Marketing & Communications department in our annual strategy session.
This typically involves 2–3 days of focused sessions covering key topics including budgeting, hiring targets, campaign reviews, and planning for the upcoming year, department strategy, and structure.
We are constantly exploring ways to optimize the Corporate Marketing & Communications department to support MDPI’s primary objectives and better convey the MDPI story while serving the scholarly community.
The strategy session also serves as a team-building activity, during which the team voted on bowling!
Strategy Session
In this strategy session, we looked at how to align our teams in order to better streamline our content with our campaigns, build a dedicated marketing team to strategically support our core MDPI products, expand our communications teams and functionalities to focus on company-critical campaigns and press releases, align our new brand design system with our marketing initiatives, set up a community and engagement team to support various teams with their outreach and communication efforts, and increase our use of data in the evaluation of campaign performance.
To grow in these areas, we will be hiring for various positions, including those of Public Relations Manager, Communications Manager, Internal Communications Manager, Campaign Manager, Marketing Associate, and Editorial Engagement Manager.

Coming Together for Science
ResearchGate and MDPI Partner to Boost the Visibility of Open Access Content through Journal Home
Stefan Tochev (CEO, MDPI) and Sören Hofmayer (Co-Founder and Chief Strategy Officer, ResearchGate) meet in Berlin, Germany to take their ongoing discussion further.
When I assumed the role of CEO at MDPI, my primary focus was to initiate the building of essential partnerships and collaborations within our industry. After all, I am a firm believer in achieving our goals by helping others achieve theirs and focusing on co-opetition wherever there is an opportunity. I first touched on the notion of co-opetition in MDPI Insights: The CEO's Letter #3, particularly when discussing collaborations with Elsevier.
In light of this, Sören Hofmayer (Co-Founder and Chief Strategy Officer at ResearchGate) and I connected recently to continue a discussion that had been ongoing for months. I was quickly brought up to speed and felt there was an opportunity for MDPI journals to pilot the Journal Home service that ResearchGate had launched. This would provide a new way for MDPI to engage with authors and readers and amplify the visibility of our journals.
While I receive many offers and opportunities for discussions with vendors, I am a firm believer that timing is everything, and in this case, the time for us is now. Sören and I met in person during my recent visit to Berlin and decided to proceed with piloting ten MDPI journals with the Journal Home service.
The press release below provides further details.
Press Release: Berlin (Germany) and Basel (Switzerland), 15 November 2023
ResearchGate, the professional network for researchers, and MDPI, the largest open access publisher in the world and a pioneer in open access publishing, today announced a partnership that will see ten of MDPI’s open access journals benefit from an enhanced presence on ResearchGate through its innovative Journal Home offering.
This new partnership will expand the reach and visibility of MDPI’s participating flagship journals with ResearchGate’s highly relevant community of more than 25 million researchers globally.
Around 210,000 version-of-record articles from these 10 titles will be readily available on ResearchGate, including the full archive material and all new articles as they are published. These journals also benefit from enhanced brand visibility, with dedicated journal profiles, prominent representation on all associated article pages and all relevant touchpoints across the ResearchGate network – keeping the journals top-of-mind with their reader and author audiences. All articles covered by the new partnership will automatically be added to the authors’ publication records in ResearchGate. This not only reduces MDPI authors’ needs for direct management but also offers them valuable insights into the impact of their work, including data about readership and citations.
Closing Thoughts
November is Men’s Health Awareness Month
Stefan Tochev (CEO, MDPI) listening to music as he writes at a coffee shop in Basel, Switzerland.
November is dedicated to raising awareness of various men’s health issues. I have been fortunate to have positive male role models in my life, and I strive to share my experiences with others.
I used to take part in Movember, growing my moustache throughout November to raise awareness and funds and to help “change the face of men’s health.” With male family and friends impacted by physical and mental health issues, I have recently become more interested in men’s overall well-being.
Men often face stigma involving the perceived need always to be strong and have things figured out. Recently, I’ve had meaningful conversations with male friends and colleagues about issues we rarely discuss, and it was a positive experience.
Various factors impact men’s health and well-being, all too easily leading to risky health behaviours including a lack of health awareness, poor health education, and negative, culturally induced, behaviour patterns in our work and personal lives. I hope we can break down these barriers in our work environment.
Healthy men help build healthy families and a healthy society
Men are less likely than women to seek help with their physical and mental health struggles. This is a reminder to prioritize your overall well-being. I hope that as men, we will continue to open up to one another, becoming vulnerable in order to share what we are going through. By sharing and by supporting each other, we can learn and grow together. You are not alone, and when you fall, you can still get up and stand tall.
From one broski to another, you are loved and appreciated. I hope this mindset carries into December and beyond.
Mindfulness
Our content team recently released a handful of articles on mindfulness, a practice that I believe provides a good opportunity for stress release and self-reflection:

MDPI Insights: The CEO's Letter #5 - OA Week, UK, and Strategy

Welcome to the MDPI Insights: The CEO's Letter.
In these monthly letters, I will showcase two key aspects of our work at MDPI: our commitment to empowering researchers and our determination to facilitating open scientific exchange.
Opening Thoughts
Open Access Week 2023 – the Global Drive to Open Continues
As the world's largest open-access (OA) publisher, we believe that unrestricted access to research findings is the cornerstone of transparency, efficiency, and quality control across scientific disciplines. At MDPI, we provide free, immediate access to scientific papers, empowering scientists to examine, validate, replicate, and build upon existing results. This minimizes redundancy, optimizes resources, and fosters innovative approaches.
International OA Week, held from 23 to 29 October 2023, provided a unique opportunity to link the global movement toward open sharing and open science with the progress of policy changes at the local level. Our mission, during OA Week and all the year round, is to offer educational resources highlighting the benefits of open-access publishing. The MDPI Blog is a valuable resource for information on open access and open science.
Core principles of OA publishing
Accessibility, transparency, and collaboration are core principles of OA publishing. OA aims to break down barriers that have traditionally restricted research access, ensuring that knowledge is available to all, regardless of financial situation or institutional affiliations. Our commitment to diverse pathways for OA publishing worldwide includes discounts for researchers. You can learn more about how MDPI supports scientific communities here.
One of the key strengths of OA publishing is its ability to facilitate interdisciplinary research. By removing paywalls and promoting knowledge-sharing across disciplines, OA encourages collaboration and innovation. Researchers from various fields can access and build upon each others’ work, fostering a holistic approach to addressing complex global challenges.
OA holds the potential to democratize knowledge, advance science, and drive positive societal change.
Policy driving change
Governments, institutions, and funding agencies have recognized the transformative potential of OA and have implemented policies to promote it. These policies often require publicly funded research to be made openly accessible, accelerating the growth of OA repositories and journals. Check out our spotlights on OA policies in the US, EU and China.
OA publishing is continuously evolving, with community-driven models and technologies shaping its future. Initiatives such as “Plan S” and “cOAlition S” promote OA publishing from the perspective of national funders, requiring grantees to publish their research openly. A new policy announced by the US administration last year mandates that, with effect from January 2026, all US federally funded research should be 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 two decades, OA publishing has been revolutionizing academic publishing by promoting 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 OA continues to expand, it holds the potential to democratize knowledge, advance science, and drive positive societal change.
MDPI is proud to lead the transition to open access.

I appreciated our frank discussion and felt that Nandita wholeheartedly supports open access. She also expressed her appreciation for the monthly CEO Letter, which she sees as a way to add personality to the MDPI brand and provide insight into the great work we do at MDPI. While we highlighted the positives, we also discussed ways to improve our communication and collaboration moving forward. This meeting alone made the trip worthwhile, and I hope Nandita doesn’t mind my sharing that she found our chat to be “the most honest and constructive discussion” she’s had with someone from MDPI in recent years.

Jelena Milojevic (Book Editor, MDPI), Jovana Dubajic (Book Editor, MDPI), Evan Escamilla (Project Manager, MDPI), Laura Wagner (Head of Books, MDPI), and Jenny Knowles (Commissioning Editor, MDPI), at the Frankfurt Book Fair in Frankfurt am Main, Germany.
For the 75th time, the Frankfurter Buchmesse opened its doors in October to celebrate exciting stories and their authors. If you haven’t yet had the chance to visit the Frankfurt Book Fair, I highly recommend it. It’s the largest book fair in the world, attracting thousands of visitors from around the globe. This is the place to gain valuable industry insights from top-class publishing professionals, connect with publishers directly, and learn about the latest trends in publishing.

Our Books team was also present at the Frankfurt Book Fair, networking and learning from various panels. Did you know that our MDPI Books department publishes OA Books?
The book publishing program includes monographs, book series, edited books and reprints of special issues and topical collections, among other book types.
If you have a book proposal you would like to discuss, please feel free to contact our Books team to understand the benefits and methods of publishing your next book with the OA model.
Closing Thoughts
MDPI Strategy Meeting
As the newly appointed CEO, this is my first year leading the MDPI Senior Management Strategy session. I saw it as an opportunity to explore what MDPI has the potential to become in the next five years. Guided by the vision of its founder and President, Dr. Shu-kun Lin, the company has accomplished remarkable feats over the past 27 years and currently holds the position as the world’s third-largest academic publisher, following Springer Nature and Elsevier.
Our primary objective is to build upon the milestones of the past decades and consolidate MDPI’s position as well-established publishing brand. The two-day meeting emphasized the importance of communicating MDPI’s values more actively via its brand and adopting a straightforward yet impactful approach to managing MDPI as a mature academic publisher.
“Our primary objective is to consolidate MDPI’s position as well-established publishing brand”
As the world’s number one open-access publisher, MDPI has long been a game-changer in the scholarly community, serving millions of authors. The challenge in being a trailblazer is the need to continuously improve and at the same time explore the next blue-ocean strategy, while also maintaining the smooth operation of the business. Our collection model, featuring guest-curated thematic topics in the form of Special Issues, has disrupted the industry. Other publishers closely study us and attempt to replicate our models. The future of this collection model is something we are actively addressing – while, of course, looking ahead to what comes next!

2023 Dark Matter Day

On and around 31 October 2017, the world celebrated the hunt for the unseen—something that scientists refer to as dark matter. Local events organized by institutions and individuals around the planet explored its mysteries, highlighting the experiments that could bring us closer to solving them. Since then, Dark Matter Day has become an annual celebration, with labs around the world taking part.
To further explore the related research on Dark Matter Day 2023, we have gathered open access academic articles on the topic of dark matter. We hope to share the most recent scientific knowledge in the field of dark matter on this special day.

Open Access Week 2023 – the Global Drive to Open Continues

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.
