PeerJ is an Open Access, peer-reviewed, scholarly journal. It considers and publishes Research Articles in the Biological and Medical Sciences. It aims for rapid decision making and will publish articles as soon as they are ready. PeerJ operates a 'Lifetime publishing plan' model. Unlike many Open Access publications which charge authors per publication, PeerJ provides low-cost publishing plans to individuals, which gives them lifetime rights to publish with PeerJ for free. The Max Planck Society covers the Enhanced Publication Plan for all Max Planck authors centrally. Further details are available on the MPDL website.

Preprint handling and circulation occurs through the well-established arXiv; the rest of the publication process, from peer refereeing through publication all the way to post-publication commenting, is offered by SciPost. SciPost does not charge individual author fees, the Max Planck Society is a supporting partner of the project.

The German Socio-Economic Panel (SOEP) is a wide-ranging representative longitudinal study of private households, located at the German Institute for Economic Research, DIW Berlin. Every year, there were nearly 11,000 households, and about 30,000 persons sampled by the fieldwork organization Kantar Public Germany. The data provide information on all household members, consisting of Germans living in the Old and New German States, Foreigners, and recent Immigrants to Germany. The Panel was started in 1984. Some of the many topics include household composition, occupational biographies, employment, earnings, health and satisfaction indicators.

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 department "Survey Data Curation", part of GESIS - Leibniz Institute for the Social Sciences, processes and prepares social science research data across a diverse range of data types to support research, especially in comparative perspectives across space and time. The curated data include long-term national (e.g., ALLBUS, GLES, Politbarometer, FReDA) and international (e.g., ISSP, EVS, CSES, Eurobarometer) survey programs with large user communities. The data are prepared for immediate re-use for research and teaching purposes. The department also offers services for linking surveys with geo-data and digital behavioral data.

The United Nations Statistics Division (UNSD) of the Department of Economic and Social Affairs (DESA) launched a new internet based data service for the global user community.

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.
