The Cognitive Linguistics Bibliography (CogBib) is an electronic database that covers a wide range of subjects within the broader field of cognitive linguistics. The most important function of CogBib is to make scholars both in and outside of the field of cognitive linguistics aware of the diverse research output available on a range of given topics.

Criminal Justice Abstracts contains of in-depth abstracts of current books, book chapters, journal articles, government reports, and dissertations published worldwide. The database also offers extensive coverage of new books from scholarly and commercial publishers and valuable reports from public and private agencies in many nations. Prepared in co-operation with the Don M. Gottfredson Library of Criminal Justice at Rutgers University Law Library, Criminal Justice Abstracts covers a wide range of topics in criminal justice, including crime trends, crime prevention and deterrence, juvenile delinquency, juvenile justice, police, courts, punishment and sentencing.

The Cross-National Time-Series database provides internationally-comparative economic variables, including government expenditure, population, territorial size, per capita GDP, trade, infrastructure, conflict events, elections, legislative process, political measures and international status indicators. Data for 200 countries is provided from 1815 onwards. Area Data, Computer Usage Data, Domestic Conflict Event Data, Economic Data, Electoral Data, Energy Data, Highway Vehicle Data, Identification Data, Industrial and Labor Force Data, Industrial Production Data, International Status Indicators Data, Legislative Process Data, Mail Data Media Data, Military Data, National Government Revenue and Expenditure Data, Phone Data, Physician Data, Political Data, Population Data, Railroad Data, School Enrollment Data, Telegraph Data, Trade Data, Urbanization Data.

Enhanced Electronic Grammars (EEG) features comprehensive descriptions of languages from around the world. Through this unique online resource, full grammars are made available together in an interlinked and semantically-annotated format, allowing granular access to the grammatical data and enabling cross-language research of several grammars at the same time. In addition to cross-linguistic queries, each grammar can also be read and researched individually.

FRANCIS indexes multilingual information and provides in-depth coverage of humanities and social sciences.

GeoReM is a Max Planck Institute database for reference materials of geological and environmental interest, such as rock powders, synthetic and natural glasses as well as mineral, isotopic, biological, river water and seawater reference materials. It contains published analytical data and compilation values (major and trace element concentrations and mass fractions, radiogenic and stable isotope ratios). GeoReM covers all important metadata about the analytical values such as uncertainty, analytical method and laboratory. Sample information and references are also included. GeoReM contains almost 3,400 reference materials, about 46,200 analyses from almost 10,000 papers, and preferred analytical values (State: November 2017).

The database GEOROC is maintained by the Geoscience Centre at Göttingen University. The database is a comprehensive collection of published analyses of volcanic rocks and mantle xenoliths. It contains major and trace element concentrations, radiogenic and nonradiogenic isotope ratios as well as analytical ages for whole rocks, glasses, minerals and inclusions. Samples come from 11 different geological settings. Metadata include, among others, geographic location with latitude and longitude, rock class and rock type, alteration grade, analytical method, laboratory, reference materials and references.

GeoScienceWorld (GSW) is a nonprofit collaborative and comprehensive resource for research and communications in the earth sciences, which is built on a core database of peer-reviewed journals and is integrated with the GeoRef index. The platforms offers a single point of access to more than 40 full text scholarly journals from leading geoscientific organizations, plus specialized searching capabilities and links to millions of relevant resources hosted elsewhere on the Web. Though access to current volumes is no longer licensed, perpetual access rights have been granted to the content published until August 2018.

Bei GovData handelt es sich um ein Metadatenportal, über das Bund, Länder und Kommunen ihre Daten zugänglich machen. Zentraler Bestandteil von GovData ist ein Metadatenkatalog. Über die darin enthaltenen standardisierten Metadaten (einheitliche strukturierte Beschreibungen) sind die Daten einfach auffindbar und zugänglich. Die Daten selbst werden weiterhin von den Datenbereitstellern dezentral vorgehalten und gepflegt.

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. The cooperation with some university institutes regarding the library exists since the foundation of the MPI-M in 1975.
