Abstract

OPACs (Online Public Access Catalogues) sind heute meist der einzige Zugang zu den Beständen einer Bibliothek, doch zeigt die Praxis, dass viele Nutzer Probleme bei der Bedienung elektronischer Kataloge haben. Ein guter OPAC muss deshalb über ein durchdachtes Online-Hilfesystem verfügen. Die Arbeit leistet eine Bestandsaufnahme und kritische Diskussion der an deutschen Universitäts-OPACs implementierten Online-Hilfesysteme. Außer den verschiedenen Formen von Hilfetexten werden dabei auch Hilfen wie Rechtschreibkorrektur, Suchergebnisfilter und Recommender miteinbezogen. Grundlagen der Analyse sind zum einen eine funktionsbezogene Klassifikation der Hilfen, zum anderen die Einführung der Begriffe Effektivität und Effizienz, die als Parameter zur Bestimmung des Nutzens eines Hilfesystems dienen. Als Ergebnis der Untersuchung stellt die Autorin Prinzipien eines effizienten Hilfesystems vor. Das Buch richtet sich an Leser aus den Bereichen Bibliotheks- und Informationswesen sowie Mensch-Maschine-Kommunikation.

Abstract

'Information science in theory and practice' berichtet über die wissenschaftlichen Erkenntnisse auf dem Feld des Informationsaustausches. Dabei werden die menschlichen und sozialen Aspekte ausführlicher behandelt als die rein technischen. Diskutiert werden die Fragen nach dem Verhalten der Menschen als Erzeuger, Empfänger und Nutzer von Informationen, der Organisiation und Funktionsweise von Informationssystemen, dem quantitativen Studium von informativen Mitteilungen, der semantischen Organisation von Mitteilungen und Kanälen mit dem Ziel der Identifizierbarmachung für Empfänger und Quelle und den Problemen bei der Informationsspeicherung, der Analyse und der Wiederauffindung. Die überarbeitete Auflage enthält außerdem aktuelle Verweise, einen neuen Anhang mit Informationen über die Forschung auf dem Gebiet der 'intelligent search interfaces' und einen neuen, detaillierten Index
