Following the completion of the Reallexikon der Germanischen Altertumskunde, containing nearly 5,000 entries on the archaeology, history and philology of North and Central Europe from the first millennium BC to the first millennium AD, two volumes of indices to this remarkable work are presented here. Apart from indices of authors and key words, as well as selected terms, there is also a systematic index arranged by subject and historical context, thus facilitating access via simple and complex key words and their thematic relationships within the lexicon.
