Abstract
Elektronische Zeitschriften bilden den Hauptanteil des Gesamtangebots an elektronischen Publikationen im Internet. Die elektronische Form bietet viele Vorteile. Elektronisches Titelmaterial kann leicht erfasst, in Datenbanken gesammelt und nach allen möglichen Kriterien durchsucht werden. Die Hyperlinktechnik erlaubt außerdem, Verbindungen zu anderen Datenbanken und zu den Volltexten herzustellen. Die Verzeichnisse elektronischer Zeitschriften zählen zu den wichtigsten und vor allem frei zugänglichen wissenschaftlichen Internetquellen. Sie werden von Verlagen, wissenschaftlichen Gesellschaften, verlagsübergreifenden Agenturen und Bibliotheken zur Einsicht angeboten. Sehr umfangreich sind die Verzeichnisse der grossen Verlage Elsevier, Springer und Wiley, noch umfassender die Master Journal List von Thomson-Reuters und die Journal List von EBSCO. Das umfassendste Verzeichnis überhaupt enthält die Elekronische Zeitschriftenbibliothek Regensburg (EZB), die einen Gesamtbestand von ca. 55000 Titeln verwaltet. In welcher Weise soll eine solche Zeitschriftendatenbank durchsucht werden? Zunächst wohl nach den in den Zeitschriftentiteln enthaltenen Wörtern, was am ehesten einer gezielten Suche nach einem bestimmten Titel entspricht. Eine nichtgezielte Suche nach noch unbekannten Titeln würde dagegen meist ins Leere gehen. So entsteht das Bedürfnis das Titelmaterial sachlich zu erschliessen. Das geschieht bei der EZB durch eine Aufteilung nach grösseren Fachgebieten. Bei Thomson-Reuters durch eine Aufteilung der Fachgebiete in engere Themengruppen. Noch stärker sind die von ExLibris mittels SFX herausgegebenen, in den USA und weltweit sehr verbreiteten Anzeigesysteme thematisch aufgegliedert.
