Popularity of Preprints Continues to Grow
2018 was a great year for preprints, with increasing numbers of authors looking to make their papers available online before peer review. Along with other preprint servers, our platform Preprints.org saw an increase in the uptake from authors, and more than double the number of announced papers compared to 2017. In fact, we recently passed two important milestones: 8000 preprints online and 30,000 authors.
We believe that the whole research community has the opportunity to benefit from work being available online as early as possible. We thank and congratulate our authors for supporting us to make this goal a reality.
In 2019, we will be looking carefully at how to provide better value for authors, maintain efficiency while growing in size, and make sure we remain well-connected with the research community.
If you want to participate, you can consider screening preprints or joining our advisory board. And, of course, posting your own work.

Open Access Agreement between the Austrian Academic Library Consortium (KEMÖ), the Austrian Science Fund (FWF), and MDPI
We are delighted to announce the establishment of our national Open Access agreement with the Austrian Academic Library Consortium (KEMÖ) and the Austrian Science Fund (FWF). Through this national agreement, the Austrian institutions listed below as well as FWF will cover the Article Processing Charges (APC) of manuscripts published by eligible corresponding or funded authors in MDPI journals as long as central funds are available.
All participating institutions have gained access to the MDPI online submission system where they can find full article metadata and pricing information as well as Funder and Grant ID details for easy identification and additional transparency. At the same time eligible authors are benefited from an APC discount which comes at no cost for the institutions.
Eligible corresponding authors affiliated with the participating institutions are prompted to choose the corresponding Institutional Open Access Program (IOAP) when they submit an article via our online submission system. The program will be selected automatically if authors submit their papers using their institutional email address. To claim their discount, FWF funded authors should choose the particular funder and add their Grant ID upon online submission of their manuscript. The institutions will then crosscheck the information and confirm the APC funding.
Eligible authors that have their APC covered by their institution or funder are advised to include the following sentence in their acknowledgments: "Open Access Funding by the [name of the institution/funder]".
The full text of the agreement is openly available online at: http://doi.org/10.5281/zenodo.2536007
For any questions about the agreement, please contact the KEMÖ Consortium at emedien@obvsg.at, FWF at Katharina.Rieck@fwf.ac.at, or the MDPI IOAP team at ioap@mdpi.com.
The Austrian institutions participating in this agreement are:
- Austrian Science Fund (FWF)
- University for Continuing Education Krems
- University of Applied Sciences BFI Vienna
- University of Applied Sciences Upper Austria
- University of Applied Sciences Technikum Wien
- Vorarlberg University of Applied Sciences

Encyclopedia—the Scholarly Community Encyclopedia

We are pleased to announce the new platform Encyclopedia, which is an online reference created and curated by active scholars. It aims to highlight the latest research results as well as providing benchmark information for researchers and the general public interested in accurate and advanced knowledge on specific topics.
We encourage authors of review articles to quote and adapt the content of their published papers to create Encyclopedia entries. You can create completely new entries on topics in which you have knowledge and expertise. There is no limit on the topics or research fields. All of science and the humanities are included. Each entry will be published directly after submission.
We also have prepared a DOI application function in Encyclopedia. Once a DOI application is approved, the entry website will announce the DOI number and a pdf version with DOI information will be automatically created.
We look forward to your contributions and hope you will make use of this service. Find more about the service at: https://encyclopedia.pub/

Institutional Open Access Agreement between Bill and Melinda Gates Foundation and MDPI

We are delighted to announce that the Bill and Melinda Gates Foundation (BMGF) is now a participant of our Institutional Open Access Program (IOAP). Authors funded by the BMGF can enjoy discounts on the APC, while the funder covers the costs of eligible articles centrally. BMGF also has access to the MDPI online submission system where they can find full article metadata and pricing information as well as Grant ID details for easy identification and additional transparency.
We hope that funded authors find the programme beneficial and we are happy to offer our IOAP to other funders that need a streamlined workflow of compliance checking and APC coverage.
To claim their discount, BMGF funded authors should choose the particular funder and add their Grant ID upon online submission of their manuscript.
For any questions about the BMGF agreement, please contact the funder at support@chronos-oa.com or the MDPI IOAP team at ioap@mdpi.com.

MDPI Welcomes Plan S
Recently, it was announced that a group of European funders supported 10 principles that will help to expand open access, known as Plan S. MDPI warmly welcomes this move as a step towards achieving more open and accessible communication of research across all disciplines. Some aspects remain to be clarified, however the details given so far match the aims and values that MDPI has held over the past two decades.
We believe that open access publishers should be active participants in discussions around Plan S, particularly regarding potential new business models and practical aspects of implementation. MDPI supports APCs as a transparent unit of payment for article publishing, however we are committed to exploring other measures and recently signed the Jussieu Call. Sustainability is a key value for MDPI, and future funding models should have at their heart the sustainability of knowledge and research dissemination. Plan S provides an opportunity for funders and publishers to directly discuss funding of open access journals in ways that are beneficial to all parties involved.

The ECATS International Association Is Now an Affiliated Society Member of Aerospace
The ECATS International Association was founded in 2005 as a Network of Excellence on Aviation and Environment of more than 100 researchers within the European Framework Research Programme. After 5 years of joint research and exploring closer collaboration, this ECATS Network of Excellence was transformed into the ECATS International Association, officially registered on 2 November 2010 by a [Royal Decree] of Belgium. Their website reflects the change from a network into an Association’s homepage.
The objective of ECATS—as laid down in its statutes—is to promote and support its members’ joint activities and interests in the field of aviation and its environmental impact, especially to help make aviation sustainable, by:
- Building up, maintaining and extending scientific expertise;
- Connecting and integrating expertise in relevant thematic areas and to fully utilize the multidisciplinary platform available in ECATS;
- Organizing exchange of information, in particular concerning experience and development of related research; e.g., via workshops, reports and publications, education and training, and web-based information;
- Aiding liaison between customers and experts to provide integrated and professional support;
- Fostering technical, strategic and political debates, for instance to initiate research work which has been identified as being crucial in certain areas.
The ECATS International Association is a professional organization whose functions are highly relevant to the scope of the Aerospace. We look forward to collaborating with ECATS International Association and publishing the state-of-the-art research from its members in this field.

MDPI establishes Open Access agreement with Qatar National Library
We are happy to announce the establishment of an Open Access (OA) agreement with Qatar National Library (QNL). QNL is committed to supporting and helping Qatar authors publish OA at no cost. Through this national agreement, QNL will cover the Article Processing Charges (APC) of manuscripts published by Qatar-based corresponding authors in MDPI journals.
Eligible corresponding authors affiliated with Qatar research centers and universities are prompted to choose QNL as part of our Institutional Open Access Program (IOAP) when they submit an article via our online submission system. The program will be selected automatically if authors submit their papers using their institutional email and/or a computer registered with the institution’s IP range. QNL will then crosscheck the information and confirm the APC funding.
Qatar authors that have their APC covered by QNL are advised to include the following sentence in their acknowledgments: "The publication of this article was funded by Qatar National Library".
For more information, please visit Open Access at QNL or email the QNL Open Access team at openaccess@qnl.qa.

The European Aeronautics Science Network (EASN) is Now an Affiliated Society Member of Aerospace
As part of the collaboration, all affiliated members of EASN will enjoy a discount on the article processing charges (APC) for article submitted to and published in Aerospace.
The long-term goal of establishing the EASN was to build up an open, unique European platform in order to structure, support, and upgrade the research activities of the European Aeronautics Universities, as well as to facilitate their response to their key roles within the European Aeronautical Research Community of incubating new knowledge and breakthrough technologies. The European Aeronautics Science Network principles have obtained the support of the commission thanks to two funded Specific Support Actions. On 6 May, 2008, the EASN Association was officially established. The association is:
- an international association based in Brussels,
- self-funded and self-sustainable,
- coordinated and run by a board of directors which is elected by the General Assembly for a three-year term.
