- "... unter diesem Motto hat die Deutsche Bücherei Leipzig am 23. März 2004 auf dem Leipziger Kongress für Bibliothek und Information eine Vortragsreihe initiiert. Vorgestellt wurden Projekte, die sich im Spannungsfeld von Standardisierung und Heterogenität der Sacherschließung bewegen. Die Benutzer unserer Bibliotheken und Informationseinrichtungen stehen heute einer Fülle von Informationen gegenüber, die sie aus zahlreichen Katalogen und Fachdatenbanken abfragen können. Diese Recherche kann schnell zeitraubend werden, wenn der Benutzer mit verschiedenen Suchbegriffen und -logiken arbeiten muss, um zur gewünschten Ressource zu gelangen. Ein Schlagwort A kann in jedem der durchsuchten Systeme eine andere Bedeutung annehmen. Homogenität erreicht man klassisch zunächst durch Normierung und Standardisierung. Für die zwei traditionellen Verfahren der inhaltlichen Erschließung - der klassifikatorischen und der verbalen - haben sich in Deutschland verschiedene Standards durchgesetzt. Klassifikatorische Erschließung wird mit ganz unterschiedlichen Systemen betrieben. Verbreitet sind etwa die Regensburger Verbundklassifikation (RVK) oder die Basisklassifikation (BK). Von Spezial- und Facheinrichtungen werden entsprechende Fachklassifikationen eingesetzt. Weltweit am häufigsten angewandt ist die Dewey Decimal Classification (DDC), die seit 2003 ins Deutsche übertragen wird. Im Bereich der verbalen Sacherschließung haben sich, vor allem bei den wissenschaftlichen Universalbibliotheken, die Regeln für den Schlagwortkatalog (RSWK) durchgesetzt, durch die zugleich die Schlagwortnormdatei (SWD) kooperativ aufgebaut wurde. Daneben erschließen wiederum viele Spezial- und Facheinrichtungen mit selbst entwickelten Fachthesauri.

- Abstract
- This article addresses a crucial issue in the digital library environment: how to support effective interaction of users with heterogeneous and distributed information resources. In particular, this study compared usability, user preference, effectiveness, and searching behaviors in systems that implement interaction with multiple databases as if they were one (integrated interaction) in a experiment in the TREC environment. 28 volunteers were recruited from the graduate students of the School of Communication, Information & Library Studies at Rutgers University. Significantly more subjects preferred the common interface to the integrated interface, mainly because they could have more control over database selection. Subjects were also more satisfied with the results from the common interface, and performed better with the common interface than with the integrated interface. Overall, it appears that for this population, interacting with databases through a common interface is preferable on all grounds to interacting with databases through an integrated interface. These results suggest that: (1) the general assumption of the information retrieval (IR) literature that an integrated interaction is best needs to be revisited; (2) it is important to allow for more user control in the distributed environment; (3) for digital library purposes, it is important to characterize different databases to support user choice for integration; and (4) certain users prefer control over database selection while still opting for results to be merged
