- Abstract
- Im Jahr 1898 begann die Library of Congress mit der Arbeit an einem Schlagwortkatalog - die Geburtsstunde der 'Library of Congress subject headings' (LCSH). Heute stellen die LCSH das zentrale Werkzeug zur verbalen inhaltlichen Erschließung in der gesamten angloamerikanischen Welt dar. Auch die Kritik an diesem Erschließungssystem hat eine lange Geschichte: Sie lässt sich bis in die Mitte des vergangenen Jahrhunderts zurückverfolgen und betraf im Lauf der Zeit recht unterschiedliche Aspekte. Neu an der Debatte der letzten Jahre ist, dass die Struktur der LCSH ganz grundsätzlich in Frage gestellt wird. Eine Projektgruppe der Bibliothek der University of California etwa urteilte 2005: "LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control." In einer für die Library of Congress erstellten Expertise mit dem Titel 'On the record' von 2008 heißt es: "LCSH suffers (...) from a structure that is cumbersome from both administrative and automation points of view". Es wird empfohlen, die LCSH in ein flexibleres Werkzeug zu verwandeln: "Transform LCSH into a tool that provides a more flexible means to create and modify subject authority data." Dies beinhaltet zum einen ein "de-coupling of subject strings", also eine 'Entkoppelung' der fest zusammengefügten (präkombinierten) Eintragungen, und zum anderen die Möglichkeit, das LCSH-Vokabular für "faceted browsing and discovery" nutzbar zu machen . Besonders drastische Worte wurden 2006 im sogenannten 'Calhoun Report' gefunden - einem Papier, das mit seinen radikalen Thesen in der amerikanischen Bibliothekswelt viel Aufsehen erregte: Man müsse die Library of Congress dazu bringen, die LCSH zu 'zerschlagen' ("urge LC to dismantle LCSH") - ja, sie gar zu 'eliminieren' ("eliminate LCSH").
