- Abstract
- Die Langzeitverfügbarkeit digitaler Medien stellt insbesondere Nationalbibliotheken vor neue Herausforderungen. Ausgehend von dieser Problematik werden Lösungsmöglichkeiten zur Gewährleistung der Langzeitverfügbarkeit für Online-Dissertationen im Rahmen des Projektes CARMEN-AP4 und des Wirkungskreises der Koordinierungsstelle "DissOnline" diskutiert sowie deren Ergebnisse und Perspektiven vorgestellt.
