Im Laufe des Jahres 2015 wird das bisherige deutsche Katalogisierungsregelwerk, die "Regeln für die alphabetische Katalogisierung" (RAK), durch einen neuen, internationalen Standard abgelöst: "Resource Description and Access" (RDA). Das am 27. März 2015 im Verlag De Gruyter erschienene Lehrbuch Basiswissen RDA von Heidrun Wiesenmüller und Silke Horny führt in das neue Regelwerk ein. Die Begleitwebsite ergänzt das Lehrbuch durch Aktualisierungen und zusätzliche Materialien und bietet außerdem in einem Blog Neuigkeiten und Informationen rund um das Thema RDA. 2. Aufl. 2017.

Abstract

Experiences with retrieval in OPACs suggest that there are major problems for the users of such systems, such as choosing the 'correct' subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Such problems relate to two facts: (1) that in the early OPACs subject access has not been considered seriously enough and (2) that the complexity of the topic has not been really recognized. Using a typology of users' questions it is demonstrated which requirements musts be met by a successful online subject access. Improvements of subject access tools are primarily aimed at, pinpointing the interplay between the different subcomponents of any subject facility: a) the features of the indexing languages used; b) the indexing principles used; c) the design and structuring of the database; and d) the possibilities of the technical retrieval facility, the search mode, and query languages. The contribution summarizes the manifold interactions between the four subcomponents listed. Any successful retrieval will heavily depend on the design of these components considering their interactions.
