Abstract

Reports a survey of all academic members of the Association of Research Libraries in the 4th quarter of 1997 which examined how academic libraries incorporate electronic information sources into their reference activities and the effects on libraries services. There was a response rate of 68 per cent, Compares results surveys carried out in 1991 and 1994. The survey covered: numbers of computers access options (intermediary, end user online, CD-ROM locally loaded databases or those accessible through the library catalogue and the Internet. There is a trend away from print resources, particularly indexing and abstracting materials, and away from CD-ROM LANs and local loading of databases towards remote online resources

Abstract

Das allerdings zu höchst unterschiedlichen Preisen. So kassiert Talking.net 1,94 Mark pro Minute Auskunftszeit über das Festnetz, während Clarity für Handy-Dienste 3,63 Mark verlangt. Angesichts von gegenwärtig vier Milliarden Internet-Seiten mit einem Zuwachs von sieben Millionen Seiten pro Tag, so die Schätzung des Internet-Forschungsinstituts Cyveillance, sind Orientierungsprobleme im Netz vorprogrammiert. Suchmaschinen werfen auf Schlagworteingabe oft eine Unzahl von Verweisen aus - und lassen den Suchenden ratlos. - Exotische Fragen - Das stellten auch die Marktforscher Fittkau & Maaß bei einer Online-Umfrage fest: 57 Prozent der Internetsurfer finden es schwierig, Informationen aufzuspüren, 36 Prozent haben Probleme, vorhandene Seiten im World Wide Web zu finden und über ein Fünftel konnte nicht einmal bereits besuchte Websites wiederfinden. Dabei hat die Info-Sintflut erst begonnen. Die School of Information und Management Systems der University of California in Berkeley hat herausgefunden, dass allein 1999 1,5 Exabyte (1,5 Millionen Terabyte) neuer Daten erzeugt wurden - das sind 1.500.000.000.000.000 Bücher im Umfang von rund 300 Seiten. Derzeit taxieren die Autoren Hal Varian und Peter Lyman das Volumen aller weltweit verfügbaren Informationen auf zwölf Exabyte (= zwölf Millionen Terabyte), bis 2003 werden noch mehr Informationen erzeugt werden. Das bedeutet: In etwas mehr als zwei Jahren entstehen mehr Informationen als in den letzten 300 000 Jahren zusammen. Angesichts solcher Zahlen dürften Auskunftsdiensten goldene Zeiten bevorstehen. Vor allem wenn komplizierte Fragen zum Geschäftskonzept gehören, wie es bei der Talking.net AG der Fall ist. Der Service ist erreichbar unter der Nummer 11821 und nennt sich ausdrücklich "Alles-Auskunft".
