Sie haben Querverweise in den Bib-Einträgen.
Aus der Dokumentation:
Wenn die Anzahl der untergeordneten Einträge, die auf einen bestimmten übergeordneten Eintrag verweisen, einen bestimmten Schwellenwert erreicht, wird der übergeordnete Eintrag automatisch zur Bibliographie hinzugefügt, auch wenn er nicht explizit zitiert wurde. Der Schwellenwert kann mit der
mincrossrefsPaketoption ... festgelegt werden.
