- Abstract
- Der Beitrag analysiert die Entstehungsgeschichte von bibliothekarischen Discovery-Systemen in Wissenschaftlichen Bibliotheken, mit einem Fokus auf Bibliotheken in Deutschland. Hierfür dient der Hype-Zyklus als Rahmen, um vor allem auch auf die Erwartungen und Rezeption der Systeme in bibliothekarischen Kreisen einzugehen und diese zu diskutieren. Der Beitrag liefert außerdem einen Ausblick auf künftige Potenziale von Discovery-Systemen, auch im Kontext von forschungsnahen Dienstleistungen.

- 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.

- Abstract
- Faceted navigation is already a standard feature of contemporary Online Public Access Catalogs (OPACs). The article aims to indicate practices in this area and new affordances that faceted navigation provides. The content of 55 Polish university library websites and their OPACs using faceted navigation was analyzed. After selecting the subject facets, the source of the terms constituting their content was analyzed using the MARC 21 bibliographic record format structure. During the transfer of traditional KOS affordances to those of faceted navigation, the former knowledge organization (KO) structures were deconstructed, which may require the creation of a new kind of KOS.

- Abstract
- This article provides an overview of computer based catalogue systems designed for use by library clients, seeing present day 'discovery systems' on the same trajectory as the older 'online public access catalogues' (OPACs) which they are gradually replacing, both in technical development and their approach to client use scenarios. It traces the history of the OPAC/discovery system from its origins in the library automation of the 1960s through to the present and discusses the main technical standards which have formed its development. The article goes on to consider questions relating to the usability of electronic library catalogues and highlights semiotic and ethical issues inherent to their design. It concludes with reflections on the future of the OPAC/discovery system in an information universe apparently dominated by the internet search engine.

- Abstract
- Due to the advances in information retrieval in the past decades, search engines have become extremely efficient at acquiring useful sources in response to a user's query. However, for more prolonged and complex information seeking tasks, these search engines are not as well suited. During complex information seeking tasks, various stages may occur, which imply varying support needs for users. However, the implications of theoretical information seeking models for concrete search user interfaces (SUI) design are unclear, both at the level of the individual features and of the whole interface. Guidelines and design patterns for concrete SUIs, on the other hand, provide recommendations for feature design, but these are separated from their role in the information seeking process. This chapter addresses the question of how to design SUIs with enhanced support for the macro-level process, first by reviewing previous research. Subsequently, we outline a framework for complex task support, which explicitly connects the temporal development of complex tasks with different levels of support by SUI features. This is followed by a discussion of concrete system examples which include elements of the three dimensions of our framework in an exploratory search and sensemaking context. Moreover, we discuss the connection of navigation with the search-oriented framework. In our final discussion and conclusion, we provide recommendations for designing more holistic SUIs which potentially evolve along with a user's information seeking process.
