Subject Indexing

Principles of classificatory and verbal indexing

Classificatory indexing

The deep and consistent subject indexing is the special positive difference between bibliographies and library catalogues respective similar resources. In the case of the Jahresberichte für deutsche Geschichte all publications contents were indexed by usage of a special faceted classification. For subject indexing the facets Chronology und Main subject groups" are particularly important. The publications were indexed as well with subject headings.

The search options thus provided are explained in the help texts in the online service and also in the introductions to the printed volumes of the Jahresberichte.

Since the reference year 2004 the following faceted classification was in use. Information on classificatory indexing of older titles befor that year can be found in the section Concordance classification.

Facet: Chronology

Systematic indexing according to periods

The temporal allocation of the items corresponds to the fourteen time or epoch spans listed below. When necessary, two time notations were assigned.

K	German statehood until 1871
L	German Empire (1871-1918)
M	Entire Twentieth Century

P	Germany (1945-1990)
Q	Postwar era until 1949
R	Federal Republic of Germany
S	German Democratic Republic

Verbal Indexing

Application of subject headings according to library standards completes subject indexing. The subject heading system contains these categories: geographic terms, persons, topics, corporate bodies and forms. It was continually updated on the basis of the German National Library’s subject authority file (Schlagwortnormdatei der Deutschen Nationalbibliothek, SWD) as well as standard reference works.

Concordance classicication for "old" titles

The classification described above is in use since the reference year 2004. In order that publications, which are indexed by usage of earlier classifications, can be found as well as the current titles in JDG's web-database, the following concordance classification was developed.
