MDPI Joins SDG Publishers Compact
UN's 17 Sustainable Development Goals (SDGs) are the blueprint to achieve a better and more sustainable future for all. In 2020 the SDG Publishers Compact was launched, aimed to inspire publishers and accelerate progress to achieve the 17 goals by 2030. Members of the programme are committed to support the publication of materials that will promote and inspire actions towards SDGs.
MDPI is an eager advocate of SDGs and has already been supporting the programme by creating Special Issues and publishing a series of books on SDGs prior to joining the Compact in 2021. MDPI's Sustainability Foundation initiated the World Sustainability Awards in 2016. We fully support UN's goals to promote sustainable actions that make the world a better place for all and, as part of its commitment, we will focus our actions on SDG10: Reduced Inequalities whilst promoting all 17 SDGs. For more details, please visit the programme’s website: https://www.un.org/sustainabledevelopment/sdg-publishers-compact/.
Joining this initiative was a unanimous decision. MDPI has in its core values the dissemination of science for all, breaking the wall between research access and under-represented members of the scientific community and the general population. To support this initiative further and continue to support under-represented scientists, MDPI will take a series of actions that will be announced once ready.
The first action MDPI takes is to nominate Dr. Liliane Auwerter as the coordinator of the programme. Dr. Auwerter studied Environmental Process Technology (UTFPR, Brazil), obtained her MSc degree in Water and Environmental Engineering (University of Surrey, UK) and in 2020 completed her PhD in self-healing low-friction materials for water transport (Imperial College London, UK), always focusing on diverse scientific projects that would potentially bring sustainability to industrial processes. As a student in Brazil, she engaged in volunteering activities focused on environmental education and took part in the Millennial Development Goals meetings held at the university.

Book Builder—Compile a Customized E-Book from Your Favorite MDPI Open Access Content
MDPI Books recently released Book Builder, a new online tool to conveniently arrange, design and produce an eBook from any content published in MDPI journals. Book Builder offers two functions: on the one hand (1) Selections, available to every registered user of MDPI; on the other hand (2) Special Issue Reprints, which can be used exclusively by Guest Editors of Special Issues.
Selections
In just a matter of a few clicks, all users are now able to assemble books from MDPI articles and receive instantaneous feedback in the form of a fully produced and compiled book (PDF), which can be downloaded or ordered as print copy. Selections can include any paper published with MDPI, picking and combining content from different journals and special issues.
This way, the user may for example choose to compile an ebook focusing around a particular topic, or assemble articles from a group of others.
We invite you to make yourself familiar with the new tool! The Book Builder can be found here: https://www.mdpi.com/books/book_builder.
Special Issue Reprints
The Book Builder allows Guest Editors of MDPI journals to create a reprint from a successfully completed Special Issue or Topical Collection in book format. If you are a Guest Editor for an MDPI journal, you can use the new tool to create an PDF document which includes all articles published in the Special Issue as well as a book cover and table of contents.
For Special Issues containing a minimum of 5 articles, the Guest Editor can request its publication on the MDPI Book platform. Published reprints are assigned an ISBN and DOI.
In addition to the PDF copy of the Reprint Book, as a token of our gratitude, MDPI offers every Guest Editor one (1) complimentary print copy (via print-on-demand). All contributors benefit from a discount on orders of any additional print copies, to share with colleagues or libraries or others.
In line with our organization's values, MDPI Books publishes all content in open access, promoting the exchange of ideas and knowledge in a globalized world. MDPI Books encompasses all the benefits of open access—high availability and visibility, as well as wide and rapid dissemination. MDPI Books are distributed under the terms and conditions of the Creative Commons Attribution License, meaning as an author you retain the copyright for your work. In addition, with MDPI Books you can complement the digital version of your work with a high-quality printed counterpart.
If you are interested in editing a book volume or series, or have a monograph manuscript to be considered for publication, please submit your proposal online and look at our Information for Authors.

MDPI Celebrates Company Milestone With 25th Anniversary Page
"We exist to help scientists achieve their own objectives"

In June of this year, MDPI will celebrate the 25th anniversary of its foundation. To mark this significant milestone, we have created a 25th Anniversary page on our website that evokes the development of our company over the past quarter-century.
MDPI has been a pioneer of Open Access publishing ever since the concept was first created.
In a wide-ranging interview, our CEO Delia Mihaila reflects on the company’s 25th anniversary and its contribution to the world of scientific publishing.
Delia considers how MDPI has evolved since starting life in 1996 as a visionary ‘project’ run out of an apartment in Basel, Switzerland, by Dr. Shu-Kun Lin. A chemist who was passionate about the long-term preservation of rare chemical sample, Dr. Lin was determined to help scholars publish their findings as quickly as possible and make their research results available to as wide a readership as possible worldwide. That determination remains unchanged 25 years later.
Today, MDPI is an international organization with over 4,000 employees based on three continents and in ten countries, and ranks among the world's top four academic publishers.
MDPI's mission is to accelerate access to new scientific research, delivering insight faster for researchers worldwide. Read more here about the company's remarkable success story and what the Open Access publishing model can offer the global scientific community.

Current Issues in Molecular Biology: Journal Publication Continued with MDPI from 2021 (Vol. 43)
The acquisition of Current Issues in Molecular Biology in February 2021 is adding to the options MDPI’s authors have who wish to publish their research in molecular biology. The title was established at the turn of the last century, in 1999, and published some 390 articles and review papers on various aspects of molecular biology and microbiology spanning from basic mechanisms to applications in adjacent fields.
Current Issues in Molecular Biology (CIMB) is going to publish original research papers and reviews which provide fundamental mechanistic and functional insights into molecular biology, in both eukaryotes and prokaryotes. There will be three issues published in 2021, and four quarterly issues as of 2022. The journal’s scope is available here: https://www.mdpi.com/journal/cimb/about.
CIMB is indexed within Scopus, SCIE (Web of Science) with Journal Impact Factor 2.695 (2019), PubMed and MEDLINE, among other databases. The journal’s CiteScore ranks in Q2 among journals listed in the “Microbiology, medical” category in Scopus.
Do not hesitate to contact the editorial office if you would like to get involved with the journal, by submitting a paper, or acting as a volunteer reviewer.
