- Abstract
- Gibt es objektive Kriterien für die Bestellung und Abbestellung wissenschaftlicher Zeitschriften? Wie lange sollte eine Bibliothek Periodikabestände benutzernah aufstellen? Kann ein Verlag -außer via Verkaufszahlen - auf Kriterien des Erfolgs seiner Zeitschriften zurückgreifen? Hat ein Autor eine Entscheidungsgrundlage, welcher Zeitschrift er seinen Artikel anbietet? Ist die Forschungsaktivität eines Instituts oder eines Wissenschaftlers über den Impact derjenigen Zeitschriftentitel zu evaluieren, die die Forschungsergebnisse drucken? Können die 'Journal Citation Reports (JCR) "des "Institute for Scientific Information" bei der Klärung solcher Fragen helfen? Sind die JCR ein nützliches oder gar ein notwendiges Hilfsmittel für Bibliotheken, für Verlage, für Wissenschaftsmanager und für wissenschaftliche Autoren? Die 'Journal Citation Reports" geben im Jahresrhythmus informetrische Kennzahlen wie die Zitationsrate, den Impact Factor, den Immediacy Index, die Halbwertszeit für eine Auswahl wissenschaftlicher Zeitschriften an. Zusätzlich berichten sie darüber, weiche Zeitschriften weiche anderen Zeitschriften zitieren bzw. von diesen zitiert werden, so dass "Soziogramme" wissenschaftlicher Zeitschriftenkommunikation entstehen. Wir wollen am Beispiel des aktuellen Jahrgangs ( 1999) die JCR detailliert beschreiben, die Auswahlkriterien der Zeitschriften beleuchten, die verwendeten informetrischen Kennwerte - vor allem den Impact Factor - kritisch hinterfragen, um danach die Einsatzgebiete bei Bibliotheken, in der Wissenschaftsevaluation, bei Verlagen und bei Autoren zu diskutieren. Das Fazit sei vorweggenommen: Die JCR sind ein nicht umgehbares Hilfsmittel für die fokussierten Anwendungsbereiche. Sie sind mitnichten frei von Problemen. Wir schließen daher mit einigen Verbesserungsvorschlägen
