Kubikat, the Library's online catalogue, is a union catalogue created in 1996 and based on the art libraries of the Kunsthistorisches Institut in Florenz, the Zentralinstitut für Kunstgeschichte in Munich and the Bibliotheca Hertziana, Max-Planck-Institut für Kunstgeschichte in Rome.
It covers the complete library holdings of the Kunsthistorisches Institut in Florenz and permits both title searches and, for acquisitions since 1996, subject searches for monographs, essays, reviews and, more recently, electronic publications. Kubikat also contains catalogue records for all printed and electronic periodicals and journals available in the library, in addition to several thousand auction catalogues.
In 2009 the Deutsches Forum für Kunstgeschichte Paris also became a member of kubikat. That same year kubikat migrated to the Bibliotheksverbund Bayern. Its holdings can now be searched via Gateway Bayern and via the Karlsruhe Virtual Catalog. In August 2014 the entire kubikat database was also uploaded to OCLC's WorldCat and is now searchable through the Art Discovery Group Catalogue.
Kubikat currently contains well over 1.7 million records, of which more than 900,000 are for articles from journals, conference proceedings, festschriften and exhibition catalogues, as well as online periodicals, from which articles are catalogued in kubikat and indexed by subject.
Within the framework of the development of next-generation catalogues, kubikat has for many years been part of the international initiative to build up an art-focused search environment for discipline-specific resources.
Launched in 2014, the Art Discovery Group Catalogue is based on the records of participating art libraries (currently more than 80 libraries from 12 countries on four continents) and is supported by the operational infrastructure and database architecture of WorldCat. The number of participating libraries continues to grow and the integration of selected resources is ongoing.
