Germanische Altertumskunde Online ( Germanic Antiquity Studies Online ) - just like the Reallexikon that has merged with it - is accompanied by supplementary volumes. This series comprises both monographs and edited volumes on specific topics from the fields of archaeology, history, and literary studies. It thus expands the database with the inclusion of aspects that require comprehensive analysis. More than 100 volumes have now appeared, from Germanenproblemen in heutiger Sicht ( The Problems of Germanic Peoples from a Contemporary Perspective ) to Germanische Altertumskunde im Wandel ( Germanic Antiquity Studies in Flux ).
