    Abstract
    Beschäftigt man sich mit Inhaltserschließung, so sind zunächst zwei Dimensionen zu unterscheiden - die Wissensorganisationssysteme selbst (z. B. Normdateien, Thesauri, Schlagwortsprachen, Klassifikationen und Ontologien) und die Metadaten für Dokumente, die mit diesen Wissensorganisationssystemen erschlossen sind. Beides steht in einer Wechselwirkung zueinander: Die Wissensorganisationssysteme sind die Werkzeuge für die Erschließungsarbeit und bilden die Grundlage für die Erstellung konkreter Erschließungsmetadaten. Die praktische Anwendung der Wissensorganisationssysteme in der Erschließung wiederum ist die Basis für deren Pflege und Weiterentwicklung. Zugleich haben Wissensorganisationssysteme auch einen Eigenwert unabhängig von den Erschließungsmetadaten für einzelne Dokumente, indem sie bestimmte Bereiche von Welt- oder Fachwissen modellartig abbilden. Will man nun Aussagen über die Qualität von inhaltlicher Erschließung treffen, so genügt es nicht, den Input - also die Wissensorganisationssysteme und die damit generierten Metadaten - zu betrachten. Man muss auch den Output betrachten, also das, was die Recherchewerkzeuge daraus machen und was folglich bei den Nutzer:innen konkret ankommt. Im vorliegenden Beitrag werden Überlegungen zur Qualität von Recherchewerkzeugen in diesem Bereich angestellt - gewissermaßen als Fortsetzung und Vertiefung der dazu im Thesenpapier des Expertenteams RDA-Anwendungsprofil für die verbale Inhaltserschließung (ET RAVI) gegebenen Hinweise. Im Zentrum steht die verbale Erschließung nach den Regeln für die Schlagwortkatalogisierung (RSWK), wie sie sich in Bibliothekskatalogen manifestiert - gleich, ob es sich dabei um herkömmliche Kataloge oder um Resource-Discovery-Systeme (RDS) handelt.
