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.

Das "Répertoire International d'Iconographie Musicale" (RIdIM) ist ein internationaler Verbund zur Verzeichnung und Erschließung von Musik- und Tanzdarstellungen im Bereich der bildenden Kunst und des Kunsthandwerks. In der "Datenbank zu Musik und Tanz in der Kunst" der RIdIM Arbeitsstelle Deutschland werden v.a. Objekte aus größeren Museen, Sammlungen und Bibliotheken in Deutschland katalogisiert. Die Erschließung der Kunstwerke in der Datenbank folgt formalen (Künstler, Titel, Entstehungsland, bzw. -ort, Technik, Datierung, besitzende Institution, Inventarnummer, etc.) und inhaltlichen Kriterien (allgemeine und musikalische Ikonographie, Musikinstrumente, allgemeine Beschreibung). Begleitend zur Katalogisierung dokumentiert die Arbeitsstelle die katalogisierten Objekte mit Bildreproduktionen.

SocArXiv, open archive of the social sciences, provides a free, non-profit, open access platform for social scientists to upload working papers, preprints, and published papers, with the option to link data and code. SocArXiv is dedicated to opening up social science, to reach more people more effectively, to improve research, and build the future of scholarly communication.

SSOAR collects electronic full texts from the domain of the Social Sciences and makes these texts available according to the Berlin Declaration on Open Access to Scientific Knowledge.

The SSRN eLibrary consists of two parts: an Abstract Database containing abstracts on over 60,500 scholarly working papers and forthcoming papers and an Electronic Paper Collection currently containing over 38,400 downloadable fulltext documents in Adobe Acrobat pdf format. The eLibrary also includes the research papers of a number of Fee Based Partner Publications.

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.

EVIFA, the portal of Social and Cultural Anthropology, offers anthropological and folkloristic information from one source. It gives a fast, comprehensive access to specific information for anthropological research, regardless of the where about.
