EconBiz - a suject portal for economics and business studies - supports you in retrieving economic literature. It offers a literature search across important German and international databases, including the holdings of ZBW, and provides access to information services of libraries. EconBiz - die Virtuelle Fachbibliothek Wirtschaftswissenschaften - unterstützt Sie bei der Recherche wirtschaftswissenschaftlicher Fachinformationen. Sie können in Internetquellen, in Online-Katalogen und Volltexten recherchieren und auf Informationsdienstleistungen von Bibliotheken zugreifen. Enthält neben aktueller Literatur viele Publikationen , die für Wirtschaftshistoriker interessant sind (1500 ff).

EconStor is the Open Access server of the German National Library of Economics, Leibniz Information Centre for Economics. EconStor provides a basis for the free publication of academic literature in economics.

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.

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.
