Abstract

Katalogisierung über den Rechner bedeutet immer auch, einen OPAC aufzubauen, der es erlaubt, nach unterschiedlichen Merkmalen - formal und sachlich - und mit deren Kombination zu recherchieren. Die Freiwortrecherche wird von den Benutzern gern verwendet, obwohl dabei die Recall Ration (Vollständigkeit) nicht ausgeschöpft wird. Die Nutzung von Schlagwörtern sollte deren Standardisierung in einer Normdatei voraussetzen, um den Subjektivismus der Katalogisierer auszuschalten. Schlagwortketten sind prinzipiell für einen OPAC überflüssig. Bei Verwendung einer hierarchischen, d.h. systematischen Klassifikation sollte deren Notation systemkohärent, flexibel und synthetisch (Facetten bzw. Schlüssel) sein. Mit Hilfe von Registern sind Schlagwörter und Systemnotationen vice versa zu verknüpfen. Wenn Sachkatalogisierung im Verbund erfolgt, bilden Terminologiekontrolle und Einheitsklassifikation als Grobsysteme wichtige Desiderate
