PLOS (Public Library of Science) is a nonprofit publisher and advocacy organization founded to accelerate progress in science and medicine by leading a transformation in research communication. PLOS entered the publishing arena in October 2003 with the launch of PLOS Biology, followed in October 2004 by PLOS Medicine. Today, it publishes a suite of influential Open Access journals across all areas of science and medicine. The Max Planck Society covers article-processing charges for Max Planck authors centrally. Further details are available on the MPDL website.

Project Euclid's mission is to advance scholarly communication in the field of theoretical and applied mathematics and statistics. The MPG licensed the EUCLID PRIME collection, a growing aggregation of well-cited, peer-reviewed journals in mathematics and statistics. Additional publications are available on an Open Access basis.

For more than 50 years, SIAM books have been a leading source of knowledge for the world's applied mathematics and computational science communities. SIAM's line-up of stellar, prize-winning authors and titles that address both timely and fundamental topics have made SIAM books indispensible to researchers, faculty, and students around the world. Now, for the first time, almost 400 books are available for institutions to offer to their users electronically.

The service "SIAM Journals Online" (SJO) provides access to the full texts of the 14 SIAM journals and to a database covering these journals.

Archive of "SIAM Journals Online" covering 17 journals.

The SpringerLink platform provides MPG staff with access to a huge collection of English and German eBooks from 2005 onwards, as well as the English and the German collection of the Springer Book Archive (1842-2004). In addition, the content of selected book series is available. Includes major reference works and dictionaries. Max Planck researchers who publish a monograph or edited volume with Springer Nature as an Open Access eBook receive a discount on the standard Book Publishing Charge. MPDL covers the costs remaining on a pro rata basis. Further details are available on the MPDL website.

The journal collection on the SpringerLink platform includes more than 2,500 English-language and close to 200 German-language journals. The current subscription provides Max Planck researchers with full text access to nearly the entire journal collection. In addition, the Max Planck Society covers article-processing charges in line with the SpringerOpen and the Springer Open Choice programmes. Further details are available on the MPDL website.

SpringerMaterials is based on the Landolt-Börnstein New Series, the unique, fully evaluated data collection in all areas of physical sciences and engineering. It is a systematic and comprehensive resource of selected and critically assessed data explained in their scientific context.

Springer Nature publishes the largest available collection of reproducible laboratory protocols and methods for the life sciences. The Experiments platform provides accees to the content from SpringerProtocols, Nature Methods, Nature Protocols and Protocol Exchange through a single easy-to-use platform, designed to save researchers' time.

The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana. Data available from TAIR includes the complete genome sequence along with gene structure, gene product information, gene expression, DNA and seed stocks, genome maps, genetic and physical markers, publications, and information about the Arabidopsis research community. Gene product function data is updated every week from the latest published research literature and community data submissions. TAIR also provides extensive linkouts from our data pages to other Arabidopsis resources. The Arabidopsis Biological Resource Center at The Ohio State University collects, reproduces, preserves and distributes seed and DNA resources of Arabidopsis thaliana and related species. Stock information and ordering for the ABRC are fully integrated into TAIR.

The German National Library of Science and Technology (TIB) ‒ Leibniz Information Centre for Science and Technology and University Library is a central specialised library, responsible for operating the German National Library for technology, architecture, chemistry, information technology, mathematics and physics as well as the University Library for Leibniz Universität Hannover. As the world's largest specialised library in its fields, the library has excellent collections of technical and scientific specialist and research information.

Archive of 15 periodicals and proceedings published online by Trans Tech Publications during the period between 1984 and 2022. The archive - with its broad subject diversity and its renowned journals indexed in well-established databases (e.g. Material Science Forum, Defect and Diffusion Forum, Key Engineering Materials) - is a valuable platform for the bibliographic retrieval of scientists, especially in the field of modern solid state and materials science.

zbMATH Open (formerly known as Zentralblatt MATH) is the world's most complete and longest running abstracting and reviewing service in pure and applied mathematics. The MATH Database contains several million entries drawn from more than 3,500 serials and journals, and more than 1,100 book series and monographs. The entries are classified according to the Mathematics Subject Classification Scheme (MSC 2000).

Zenodo is an open data repository, developed and operated by CERN. It is an catch-all repository, that welcomes research from all over the world, and from every discipline. Zenodo does not impose any requirements on format, size, access restrictions or licence. A digital object identifier (DOI) is automatically assigned to all Zenodo files and it is integrated into reporting for research funded by the European Commission.
