    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
    Bekanntlich führen Suchmaschinen wie Google &Co. beider Auflistung der Suchergebnisse ein "Ranking" nach "Relevanz" durch, d.h. die Dokumente werden in absteigender Reihenfolge entsprechend ihrer Erfüllung von Relevanzkriterien ausgeben. In Online-Katalogen (OPACs) ist derlei noch nicht allgemein übliche Praxis, doch bietet etwa das im Österreichischen Bibliothekenverbund eingesetzte System Aleph 500 tatsächlich eine solche Ranking-Option an (die im Verbundkatalog auch implementiert ist). Bislang liegen allerdings kaum Informationen zur Funktionsweise dieses Features, insbesondere auch im Hinblick auf eine Hilfestellung für Benutzer, vor. Daher möchten wir mit diesem Beitrag versuchen, den in unserem Verbund bestehenden Informationsstand zum Thema "Relevance Ranking" zu erweitern. Sowohl die Verwendung einer Ranking-Option in OPACs generell als auch die sich unter Aleph 500 konkret bietenden Möglichkeiten sollen im folgenden näher betrachtet werden.

    Abstract
    Die DBV-Rechtskommission hält es für urheberrechtlich fragwürdig, wenn eine Bibliothek ihren OPAC mit Coverabbildungen anreichert. Wenn eine Bibliothek die Coverabbildung eines Buches in ihren im Internet frei zugänglichen OPAC einfügt, dann macht sie damit ein fremdes Werk "öffentlich zugänglich" (§ 19a UrhG), da das Cover als eigenständiges Werk urheberrechtlich geschützt ist. Das Recht der öffentlichen Zugänglichmachung gemäß § 19a UrhG steht dem Autor/Urheber zu. Deshalb müsste die Bibliothek die Genehmigung des Rechtsinhabers einholen, bevor sie sein Werk im Internet zugänglich macht. Bei der Vielzahl der Rechtsinhaber ist dies aber praktisch kaum zu bewältigen. Manche Bibliothek nutzt deshalb die Webseiten von Online-Buchhändlern. Die DBV-Rechtskommission bezweifelt, dass Amazon oder andere Anbieter Nutzungsrechte an Coverabbildungen auf Dritte, d.h. Bibliotheken, rechtswirksam übertragen können und dürfen. Deshalb rät die Kommission derzeit noch allen Bibliotheken, keine Bilder in ihren OPAC zu integrieren.
