Abstract

Wissenschaftliche Informationen im Internet gewinnen zunehmend an Bedeutung. Um sie als zuverlässige Ressourcen für die wissenschaftliche Arbeit zu erschließen, müssen sie auf ihre Qualität geprüft werden - eine Aufgabe, die vermehrt von wissenschaftlichen Bibliotheken über ihre Internetdienste wie Subject Gateways, Digitale oder Virtuelle Bibliotheken wahrgenommen wird. Der vorliegende Artikel bietet eine medientheoretische Diskussion zum wissenschaftlichen Informationsraum im Internet und den medienbedingten Auswirkungen auf die Inhalte sowie einen Überblick zur Entwicklung von Evaluationsansätzen für Internetressourcen. Die theoretischen Abhandlungen werden durch einen umfangreichen Serviceteil ergänzt, der detailliert Qualitätskriterien und den Evaluierungsprozess in einer Weise aufzeigt, welche die Anpassung an (fach-)spezifische Anforderungen ermöglicht.
