Abstract

Auf dem Hintergrund der aktuellen OPAC-Entwicklung in Deutschland werden im ersten Teil einzelne Aspekte des OPAC-Designs kommentiert. Es wird u.a. auch auf Möglichkeiten einer Standardisierung der Schnittstelle Retrieval-Software / Benutzeroberfläche eingegangen. Die derzeit dominierenden Online-Kataloge sind für eine Massenbenutzung nur bedingt geeignet, da sie in hohem Maße fehlerintolerant sind, eine Analyse nach Suchfeldern verlangen und mit grundsätzlichen Mängeln der Boole'schen Suchlogik behaftet sind. Im zweiten Teil werden werden Alternativen diskutiert, zum einen in Form eines alphabetisch sortierten Online-Katalogs, zum anderen in Form intelligenter bibliographischer Auskunftssysteme, die Ähnlichkeitssuchen bzw. sog. 'Closest-Match-Suchen' gestatten. Hierzu werden verschiedene Konzepte und Vorschläge vorgestellt
