The Subject Catalogue of the "Römisch-Germanische Kommission" (Departement for Pre- and Protohistory of Europe in Frankfurt, DAI) 1992-2010
The library of the Departement for Pre- and Protohistory of Europe in Frankfurt started with the thematic collection of all new acquisitions in March 1992. A system was developed which especially classifies the aspects of the cultures, the landscapes, the dating and the type of artefacts, works of art and buildings.
Not only the monographic new acquisitions are classified in this way, but also and in particular the so-called non-independent or secondary literature, i.e. all journal articles and contributions to collected editions. A selection of around 14,000 subject headings and key-words is thus currently available for detailed literature research, and the number of key-words is constantly growing.
The database is containing about 600,000 subject headings; 180,000 citations of 67,000 authors; only 44,000 are monographs.
