Digi20 concentrates on the digitalization of monographs published in the second half of the 20th century, predominantly in the field of humanities and social sciences. In the first phase of the project, approx. 4,700 titles of programme segments of the publishers Vandenhoeck & Ruprecht, Wilhelm Fink / Ferdinand Schöningh as well as Otto Sagner were digitized. In a second phase, further approx. 1,750 titles are being included till 2014 by consecutively digitizing all monographs up to a defined ‘Moving Wall’ of three to five years to the current year of publication.

Frontiers is a community-oriented open-access academic publisher and research network. It was launched in 2007 by scientists from the Swiss Federal Institute of Technology in Lausanne and aims to provide better tools and services to researchers in the Internet age. Since then, Frontiers has become one of the fastest-growing open-access scholarly publishers: over 400,000 high-quality, peer-reviewed articles have been published in about 200 community-driven journals across more than 300 specialty niches in science, medicine and technology. The Max Planck Society covers article-processing charges for Max Planck authors centrally. Further details are available on the MPDL website.

Language Description Heritage (LDH) provides open access to descriptive material about the world's languages with a focus on traditionally difficult to obtain works. This collection is being compiled at first by the Max Planck Institute for Evolutionary Anthropology and now by the Max Planck Institute for the Science of Human History. -- Language Description Heritage (LDH) ist eine Datenbank, die freien Zugriff auf deskriptive Materialien zu den Sprachen der Welt gewährt. Dabei legt den Schwerpunkt auf überlicherweise schwer erhältlich Arbeiten. Die Sammlung wurde zuerst am Max-Planck-Institut für Evolutionäre Anthropology angelegt und wird nun am Max-Planck-Institut für Menschheitsgeschichte fortgeführt.

LIVIVO bundles scientifically relevant resources from the subjects fields medicine, health, nutrition, environmental and agricultural sciences. It provides a common search interface over various data sources, such as library catalogs, specialist bibliographic databases, full texts from journals, and quality-controlled web content. LIVIVO combines the former ZB MED search portals MEDPILOT (2003 to 2015) and GREENPILOT (2009 to 2015).

The MPI EVA Library Catalogue provides information on books and journals available from the Institute's library.

The OSF Preprints search combines records from various preprint repositories, including arXiv, bioRxiv, Cogprints, PeerJ, PsyArXiv, RePEc and SocArXiv.

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.

WALS is a large database of structural (phonological, grammatical, lexical) properties of languages gathered from descriptive materials (such as reference grammars) by a team of more than 40 authors (many of them the leading authorities on the subject). WALS consists of a number of maps with accompanying texts on diverse features (such as vowel inventory size, noun-genitive order, passive constructions, and "hand"/"arm" polysemy), each of which is the responsibility of a single author (or team of authors). Each map shows between 120 and 1370 languages, each language being represented by a symbol, and different symbols showing different values of the feature.

The World Loanword Database, edited by Martin Haspelmath and Uri Tadmor, is a scientific publication by the Max Planck Institute for Evolutionary Anthropology. It provides vocabularies (mini-dictionaries of about 1000-2000 entries) of 41 languages from around the world, with comprehensive information about the loanword status of each word. It allows users to find loanwords, source words and donor languages in each of the 41 languages, but also makes it easy to compare loanwords across languages. Each vocabulary was contributed by an expert on the language and its history. An accompanying book has been published by De Gruyter Mouton (Loanwords in the World's Languages: A Comparative Handbook, edited by Martin Haspelmath & Uri Tadmor). The World Loanword Database consists of vocabularies contributed by 41 different authors or author teams.
