- Abstract
- This article gives an overview of the design and organisation of DutchESS, a Dutch information subject gateway created as a national collaborative effort of the National Library and a number of academic libraries. The combined centralised and distributed model of DutchESS is discussed, as well as its selection policy, its metadata format, classification scheme and retrieval options. Also some options for future collaboration on an international level are explored

- Abstract
- Although researchers have theorized the critical importance of classification in the organization of information, the classification approach seems to have given way to the alphabetical subject approach in retrieval tools widely used in libraries, and research an how users utilize classification or classification-like arrangements in information seeking has been scant. To better understand whether searchers consider classificatory structures a viable alternative to information retrieval, this article reports an a study of how 24 library and information science students used Yahoo! directories, a popular search service resembling classification, in completing an assigned simple task. Several issues emerged from the students' reporting of their search process and a comparison between hierarchical navigation and keyword searching: citation order of facets, precision vs. recall, and other factors influencing searchers' successes and preferences. The latter included search expertise, knowledge of the discipline, and time required to complete the search. Without a definitive conclusion, we suggest a number of directoons for further research.

- Abstract
- Historische Rezensionen online (HR O) ist eine auf geschichtswissenschaftliche Rezensionen fokussierte Suchmaschine. Sie berücksichtigt ausschließlich fachwissenschaftliche Besprechungen, die im Web veröffentlicht wurden und ohne Zugangsbeschränkungen im Volltext zur Verfügung stehen. Eingebunden in das Portal des DFG-geförderten Kooperationsprojektes Clio-online sind über eine einfache Suchmaske gegenwärtig mehr als 35.000 Rezensionen zu über 30.000 Publikationen im Volltext recherchierbar. Statt unter hohem Aufwand Daten zu erstellen oder manuell zu katalogisieren, werden bei HRO bereits vorhandene Texte und bibliografische Daten voll automatisiert gesammelt, verknüpft und in einem zentralen Suchindex aufbereitet. Die Spezialisierung auf eine Textsorte und die Anreicherung der Rezensionstexte mit den in der Verbunddatenbank des GBV bereits erfassten bibliografischen Informationen erlauben zudem zielgerichtete Anfragen nach bestimmten Autoren oder eingeschränkt auf einzelne Themenbereiche, ein Mehrwert für die Nutzerinnen und Nutzer von HRO gegenüber kommerziellen Suchmaschinen.

- Abstract
- The current subject gateways have evolved over time when the discipline of Internet resource discovery was in its infancy. This is reflected by the lack of well-established, light-weight, deployable, easy-to-use, standards for metadata and information retrieval. We provide an introduction to the architecture, standards and software solutions in use by subject gateways, and to the issues that must be addressed to support future subject gateways

- Abstract
- Suchmaschinen stellen eine wichtige Möglichkeit dar, um neue Informationen oder Webseiten im Internet zu finden. Das Online-Marketing wurde dadurch verstärkt auf das Suchmaschinen-Marketing ausgerichtet, bei dem vor allem darauf geachtet wird, dass man in Suchmaschinen gut sichtbar ist. Bei der effizienten Planung von Marketing-Aktionen ist es deshalb wichtig, nicht nur profunde Kenntnisse über die Funktionsweise von Suchmaschinen zu haben, sondern auch das Suchverhalten von Suchmaschinennutzern zu untersuchen und die Ergebnisse geeignet umzusetzen. In diesem Beitrag wird auf die Erforschung des Suchverhaltens im Web und auf die Interaktion von Menschen mit Suchmaschinen ab 1997 eingegangen. In erster Linie werden verschiedene Erhebungsmethoden erklärt und Analysen vorgestellt. Es wird auch diskutiert, wie die Ergebnisse umgesetzt werden können, um die Auffindbarkeit von Webseiten zu verbessern.

- Abstract
- Children are increasingly using the Web. Cognitive theory tells us that directory structures are especially suited for information retrieval by children; however, empirical results show that they prefer keyword searching. One of the reasons for these findings could be that the directory structures and terminology are created by grown-ups. Using a card-sorting method and an enveloping system, we simulated the structure of a directory. Our goal was to try to understand what browsable, hierarchical subject categories children create when suggested terms are supplied and they are free to add or delete terms. Twelve groups of four children each (fourth and fifth graders) participated in our exploratory study. The initial terminology presented to the children was based on names of categories used in popular directories, in the sections on Arts, Television, Music, Cinema, and Celebrities. The children were allowed to introduce additional cards and change the terms appearing on the 61 cards. Findings show that the different groups reached reasonable consensus; the majority of the category names used by existing directories were acceptable by them and only a small minority of the terms caused confusion. Our recommendation is to include children in the design process of directories, not only in designing the interface but also in designing the content structure as well.

- Abstract
- Google will in diesen Tagen im Rahmen eines Zehn-Jahres-Projektes mit dem Scannen von 15 Millionen Büchern von der Oxford University, Harvard University, Stanford University, der University of Michigan und der New York Public Library beginnen. Die Bücher, bei denen alle Copyrights erloschen sind, werden vollständig online gebracht. Aus den anderen Büchern sollen Auszüge offeriert werden. Password-Partner David Worlock (London) kommentierte den Sprung von Google in die gedruckte Welt: "More than anything, the acceleration of Google's engagement with the analog, printed world represents a decisive moment in the evolution of information publishing- toward providing "solutions" rather than the passive information assets that Google may be an the way to providing as a content utility. As its strategy unfolds, and its competitors respond, muck of the still substantially offline world of publishers, booksellers, and institutional collections, will see a year of changed assumptions and dissolving boundaries."

- Abstract
- Im Rahmen eines berufspraktischen Studiensemesters bei der T-Online AG (Darmstadt) wurden Suchmaschinen und Portale mit integrierter Suchfunktion hinsichtlich Funktionalität und Usability untersucht. Ausgehend von der von Fauldrath und Kunisch bereits 2005 durchgeführten Untersuchung wurde erneut geprüft, welche Standards sich bei den Suchdienstanbietern etabliert haben und welche Trends erkennbar sind. Der bei der zurückliegenden Evaluation verwendete Kriterienkatalog wurde um einige Kriterien erweitert und als Bewertungsschablone der vorliegenden Evaluation eingesetzt. Besonders wichtig für den Nutzwert eines Suchdienstes ist die Relevanz der Treffer. Der bisher weit verbreitete Weg, entsprechende Spezialsuchen anzubieten, verkompliziert die Benutzung der Suchmaschine erheblich, weshalb auch aufgezeigt wird, welche Strategien die Suchdienste zur besseren Antizipierung des Nutzer-Informationsbedürfnisses bereitstellen. Die somit erzielte verbesserte Einbindung eigener Dienste und Inhalte stellt einen enormen Gewinn dar, da sowohl Nutzer als auch Anbieter gleichermaßen davon profitieren.
