The Research Data Centre (FDZ) of the German Federal Employment Agency (BA) at the Institute for Employment Research (IAB) is intended mainly to facilitate access to BA and IAB micro data for non-commercial empirical research using standardised and transparent access rules. The FDZ mediates between data producers and external users, and also controls for compliance with data protection regulations.

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.

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

The Library and Information Service (BIS) is the joint library for the Max-Planck-Institute for Meteorology (MPI-M) and five institutes of the Center for Earth System Science and Sustainability.
