The thematic thesaurus allows you a thematic access on the digitized titles on Archaeology and on Egyptology. The structure of the thesaurus is leaving ajar on the subject indexing vocabulary of the German Institute of Archaeology (DAI), completed with records on the Egyptian culture. The both icons beside the titles as the ‘Griffon’ of the DAI and the logo of the Heidelberg University Library show you the provenance of the digitized title.
