    Abstract
    Zitationen spielen eine wichtige Rolle im wissenschaftlichen Diskurs, in der Recherchepraxis sowie im Bereich der Bibliometrie. In jüngster Zeit gibt es zunehmend Initiativen, die Zitationen als Open Data zur freien Nachnutzung verfügbar machen. Der Beitrag beschreibt den Stand der Entwicklung dieser Initiativen und zeigt, dass in nächster Zeit eine kritische Masse von Daten entstehen könnte, aus denen sich gerade für Bibliotheken neue Perspektiven ergeben. Als konkrete Möglichkeit zur Partizipation für Bibliotheken wird das DFG-Projekt Linked Open Citation Database (LOC-DB) vorgestellt.
