A digital archive of life sciences journal literature managed by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).

The Royal Society publishes 9 high quality, peer reviewed journals covering the full breadth of the biological, physical and cross-disciplinary science. The Royal Society’s Philosophical Transactions, launched in 1665, was the world’s first scientific journal. It established the fundamental principles of scientific priority and peer review, used throughout scientific publishing ever since. Max Planck researchers have free access to historical journal archives. In addition, the Max Planck Society covers article-processing charges for Max Planck authors publishing in selected journals centrally. Further details are available on the MPDL website.

The RSC publishing platform provides access to electronic journals and books from the Royal Society of Chemistry. From this page, you can reach over 1 million chemical science articles and chapters. Users from the MPG have access to the entire journal collection, including the RSC journals archive covering articles published back to 1841. In addition, a collection of about 900 ebooks was purchased within the scope of the German national licenses program. The Max Planck Society also covers article-processing charges in line with the RSC "Read & Publish" agreement. Further details are available on the MPDL website.

The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 13 million records covering publications in Astronomy and Astrophysics, Physics, and the arXiv e-prints. Abstracts and full-text of major astronomy and physics publications are indexed and searchable through the new ADS modern search form as well as a classic search form.

ScienceOpen is a networking platform for scholars to enhance their research in the open, make an impact, and receive credit for it. The site provides advanced search and discovery functions, combined with post-publication peer review, recommendation, social sharing, and collection-building features. The Max Planck Society covers article-processing charges for ScienceOpen Research and ScienceOpen Poster centrally. Further details are available on the MPDL website.

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.

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.

Ullmann's Encyclopedia of Industrial Chemistry covers the science and technology of all areas of industrial chemistry. For each chemical substance, information on physical and chemical properties, production, applications, economic data, toxicology and occupational health is given.

The MPI-Mainz-UV-VIS Spectral Atlas is a comprehensive collection of absorption cross sections for gaseous molecules and radicals, primarily relevant to atmospheric research, from measurements performed during the last nine decades. The individual data sets were collected from the original publications, either copied from tabulations, or read from figures in those cases where numerical data could no longer be obtained. Other sources rely on the internal databases of several research centers dealing with atmospheric chemistry and/or molecular spectroscopy. Numerous excellent high-resolution spectra were obtained from personal communications with the scientists.

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.
