Within the Institute itself, library users have access to databases licensed by the Institute or the MPG (Max Planck Society) and to those available freely on the internet, this via the DBIS database information system operated by the University Library of Regensburg.
Library users also have access to academic full text journals via the EZB (Electronic Periodicals Library) within the Institute. These include the range of periodicals licensed by the Institute, almost all the titles included in the Max Planck Society's licensing subscription and those journals which are freely available on the internet itself.
In addition to electronic journals, the library provides full-text access to a constantly growing collection of e-books. These are offered by the MPG as well as German national licenses and can be consulted on all PC workstations within the KHI's intranet. Search within the collection can be conducted via the e-book catalog of the Max Planck Society.
DLC – developed by the library in cooperation with the Max Planck Digital Library (MPDL) and other Max Planck Institutes – is a platform for the publication of digitized documents, predominantly held by the participating libraries. Since 2013, the KHI has been able to provide digitized books from its own rare book section, which are in part enriched with related structural data, free of charge in this portal. Titles are grouped according to subject fields. The advanced search function allows retrieval using single or combined terms such as the title, contents, full text where applicable and, moreover, codicological metadata (description of the volume with information about condition, marginal glosses, handwritten ex-libris remarks, ex-libris, etc.). The digital collection of the KHI will be added to continuously.
As a central specialist portal, the virtual specialist library of art history, or arthistoricum.net, provides access to a diverse range of information on the subject of art history. This information includes catalogues, databases, full text collections, internet resources, thematic portals, reviews and much more. The portal’s modular design is conducive to mutual maintenance and continual service upgrades.
The eRessource Navigator is an academic information portal operated by the Max Planck Society, which provides access to all Max Planck Institute library catalogues in addition to external catalogues, licensed reference databases, reference works, e-print servers, etc., through a common user interface.
