Title: WorldCat ausgebaut

Abstract: Mit 84 Millionen bibliografischen Einträgen und mehr als einer Milliarde Besitznachweisen aus ca. 10.000 Institutionen ist der WorldCat das größte Nachweisinstrument für Bibliotheksbestände weltweit. Der Sucheinstieg über WorldCat.org (www.worldcat.org) bietet eine einfache Stichwortsuche in der gesamten Datenbank von WorldCat und nicht nur in den Teilmengen, die über Open WorldCat (http://www.oclc.org/worldcat/open/default.htm) frei genutzt werden können. Inzwischen sind rund 7,9 Millionen Einträge der Deutschen Nationalbibliothek aus den Jahren 1913 bis 2007 im WorldCat des OCLC (Online Computer Library Center) nachgewiesen Monatlich kommen allein aus der DNB mehr als 15.000 Titeldatensätze dazu. Neben der DNB ist derzeit als weitere deutsche Bibliothek die Staats- und Universitätsbibliothek Göttingen im WorldCat vertreten. Die Bayerische Staatsbibliothek sowie die Verbünde GBV und BSZ haben Vereinbarungen für die Datenlieferung getroffen. Seit März 2007 sind auch Nachweise für Aufsätze in die WorldCat.org-Suche einbezogen. Es handelt sich um die vier Datenbanken GPO, ArticleFirst, Medline und ERIC. WorldCat.org bietet damit mehr Titel als der WorldCat selbst, da diese Kurznachweise im WorldCat nicht recherchierbar sind. Bei den zwei großen deutschen Bibliotheken, die bisher im WorldCat präsent sind, SUB Göttingen und DNB, führen bei Besitzmeldung zur entsprechenden Zeitschrift die Bibliotheks-Links im WorldCat.org direkt in deren Kataloge oder auch in die ZDB.
