Abstract
Im Mittelpunkt dieses Kapitels steht die praktische Informationssuche (Information Retrival, Online Retrieval, Online Recherche) in den qualitativ hochwertigen und gut strukturierten Online-Datenbanken (Informations-Datenbanken). Die hohe Qualität ihrer Informationsinhalte wird durch eine entsprechende fachliche Auswahl und Bearbeitung der Informationen schergestellt. Die detaillierte Strukturierung der gespeicherten Datenbank-Inhalte in Felder (z.B. Namen, Umsatz, Beschäftigte, Jahr) ist eine wichtige Voraussetzung für die Beantwortung komlexer und sehr spezifischer Fragestellungen professioneller Nutzer. Diese-kostenpflichtigen-traditionellen Online-Datenbanken behaupten sich weiterhin wegen der genannten Vorteile gegenüber den in der Regel kostenlosen Informationsangeboten des "chaotischen" Internets (siehe Kap. C 3 Metainformationsdienste im Internet). Da alle Online-Datenbanken über eine entsprechende Web-Oberfläche von den Nutzern erreicht werden können, wurden damit die Recherchedurchführung erleichtert und neue Nutzergruppen erschlossen. Die Benutzung dieser Online-Datenbanken wird nachfolgend an Hand praktischer Recherchebeispiele erläutert, über die theoretischen Grundlagen des Information Retrievals informieren die Kap. B 7 - B 9. Die Internet-Suchmaschinen werden in Kap. C 3 behandelt.
