Abstract
Elsevier Science hat die eigens für wissenschaftliche Inhalte entwickelte Suchmaschine Scirus nach Abschluss des weltweiten Betatestes gestartet (www.scirus.com). Wissenschaftler haben gegenüber den allgemeinen Suchmaschinen Vorbehalte, weil die Nicht-Berücksichtigung wissenschaftlicher Spezifika "unglaublich beeinträchtigen kann" (Prof. Dr. Franz Guenther, Universität München). Scirus hat bislang 60 Millionen wissenschaftsbezogene Seiten im Internet und die Elsevier Science-Quellen Science Direct, BioMedNet und ChemWeb erfasst und kann auch Seiten im Format PDF oder Postscript lesen. Der Anbieter befindet sich derzeit in Abschlussverhandlungen mit anderen Fachverlagen, um deren Datenbanken in die Suche über Scirus einbeziehen zu können. Science ist auch als Websuchfunktion über ScienceDirect erhältlich; www.sciencedirect.com. Technisch realisiert wurde die Suchmaschine durch den Einsatz von FastSearch, die auch von Reed Elsevier, Dell, Ericsson, Lycos und TIBCO Software eingesetzt wird. Elsevier Science sieht sich als der weltweit größte Anbieter von wissenschaftlichen, technischen und medizinischen Informationen. Den Abonnenten von Science Direct wird derzeit der VolltextZugang zu etwa 1.200 Zeitschriften geboten
