    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

    Abstract
    An exploratory research study on OPACs was done within the framework of the French PARINFO program by four different teams: ENSSIB-CERSI, City Univ. of London, Médiathèque of the Cité des Sciences et de l'industrie and a firm GSI-ERLI. During the month of June 1992, 650 individual searches on four terminals were collected. The sessions were automatically recorded, accompanied by two online questionnaires, a pre-search and a post-search questionnaire. Some questions were asked orally by an interviewer and the answers noted. The article analyses the researches perceived by user as difficult or impossible. Some examples of the difficulties are given
