- Abstract
- A study group representing four European national libraries (the Swiss National Library, Die Deutsche Bibliothek, the Bibliothèque nationale de France and The British Library) recently conducted a study on the possibility of establishing multilingual thesaural links between the headings in the LCSH authority file and the authority files of the German indexing system SWD/RSWK and the French indexing system RAMEAU. The study demonstrated a high level of correspondence in main headings, but also revealed a number of issues requiring further investigation. The study group's findings led to recommendations on the scope for the development of a prototype system for linking the three Subject Heading Languages (SHLs) in the databases of the four institutions

- - Retrievalmöglichkeiten - Ein Test der Retrievalmöglichkeiten von Zeitangaben in den Online-Katalogen der LoC, BnF und DDB zeigte, dass für ein optimales Suchergebnis viele Recherche-Schritte und Regelwerkskenntnisse notwendig sind, eine aus Nutzersicht unbefriedigende Bilanz. Zum Beispiel muss für Suchanfragen nach Jahreszahlen der Zeitraum genauso angegeben werden, wie es bei der Indexierung geschah, oder eine Suche mit Epochenbegriffen und zeitimmanenten Schlagwörtern erfordert die genaue Kenntnis der Ansetzungsregeln für solche Deskriptoren. Die angebotenen Schlagwortketten sind eine Suchhilfe, erlauben aber keine Sortierung nach der Zeitenabfolge. Der größte Mangel ist, dass alle Zeitcodierungen nur als Zeichen, nicht als Zahlen, erkennbar sind, sodass bei der Suche nur ein Zeichenabgleich erfolgt und keine Sortierung nach Zahlen möglich ist. Jutta Frommeyer stellt die Retrievalmöglichkeiten der drei genannten Bibliothekskataloge verschiedenen anderen Datenbanken gegenüber, die eine Suche nach Zeitangaben anbieten. Die Suchmöglichkeiten bei den Allgemeinenzyklopädien (»Encyclopedia Britannica«, »Brockhaus-Enzyklopädie«, »Encarta«) sind vielfältig und elaboriert. Zeitimmanente Begriffe sind chronologisch angeordnet und auch grafisch durch Zeitschienen dargestellt, von denen aus auf ein Jahr oder einen Zeitbegriff gesprungen werden kann. Die Datenbank »Historical abstracts« bietet den Zeitraum, der in einem Dokument behandelt wird, über eine spezielle Codierung an. Die »Jahresberichte für deutsche Geschichte« bieten für das Zeitretrieval eine Tabelle mit 14 verschiedenen Möglichkeiten; die weitere Differenzierung der Suchanfrage erfolgt hier durch andere Sacherschließungselemente wie eine ausgefeilte Klassifikation und eine Schlagwortliste. - Modell zum optimalen Zeitretrieval - Aufgrund ihrer Untersuchungen entwickelt die Autorin ein theoretisches Modell für ein optimales Zeitretrieval in allgemeinbibliografischen Datenbanken mit den drei Elementen Zeitcode, Chronikcode und Chroniknormdatei. Damit die Zeitcodierungen als Zahlen und nicht als Zeichen erkennbar sind, müssen sie in einem besonderen numerischen Feld (Zeitcode) abgelegt werden; mit der Möglichkeit, nach Zeiträumen zu suchen (Größer-, Kleiner- und Gleichoperatoren). Die Zeitspannen von Zeitbegriffen werden als Chronikcode in der gleichen Datenstruktur wie der Zeitcode bei den Normdatensätzen ergänzt. Für bestimmte Zeitbegriffe ist eine Normierung notwendig (z. B. Mittelalter). Bei kulturkreisabhängigen Zeitbegriffen kann die zeitliche Codierung verschieden aussehen. Die Chroniknormdatei soll die chronologische Relation der zeitimmanenten Begriffe darstellen und bei umfassenden Zeitspannen große Trefferzahlen vermeiden. Da zeitimmanente Begriffe über alle Sachgebiete streuen, muss für das Retrieval eine sachliche Einschränkung gegeben sein. Jutta Frommeyer schlägt dafür eine international angewandte Klassifikation vor. Die Autorin stellt ein Retrievalmodell dar, um das Zusammenwirken von Zeitcode,Chronikcode und Chroniknormdatei zu demonstrieren. Dabei hat sie sich an der heutigen Menü-Oberfläche für OPACs orientiert und ein neues Suchfeld »Zeitabschnitt« mit verschiedenen Unterteilungen eingeführt. Ihre Beispiele sind nachvollziehbar und verdeutlichen ihren Vorschlag. Die Umsetzung eines solchen Modells hat Auswirkungen auf die vorhandenen Datenstrukturen; auch wird eine Annäherung der Regeln für die Schlagwortvergabe nach RSWK, Rameau und LCSH notwendig sein, wenn so eine Suche international angeboten werden soll.
- Zum Schluss - Das Buch liest sich gut und ist übersichtlich gegliedert mit zehn Kapiteln und einem Anhang für verschiedene, den Zeitaspekt betreffende Hilfstabellen der vorgestellten Sacherschließungssysteme. Wo möglich und angebracht, insbesondere bei der Darstellung der Retrievalmöglichkeiten der untersuchten elektronischen Informationsmittel, werden zur Veranschaulichung Abbildungen eingesetzt. Allerdings sind der Qualität Grenzen gesetzt, weil im Schwarz-Druck ein ursprünglich farbiges Benutzer-Interface manchmal fast seine ganze Aussagekraft verliert. Hier wäre es wahrscheinlich besser gewesen, die benötigten Abbildungen vorher über ein Grafik-Programm in eine richtige Schwarz-Weiß-Abbildung umgesetzt zu haben. Das Literaturverzeichnis ist umfangreich und sehr übersichtlich gestaltet. Das Buch bietet denjenigen, die sich mit Sacherschließung oder OPAC-Entwicklung beschäftigen, wichtige Anregungen. Die Notwendigkeit von Sacherschließung gerade im Zeitalter der Globalisierung und des Internets bedeutet, dass bei der Weiterentwicklung von nationalen Regelwerken die internationalen Bedürfnisse berücksichtigt werden müssen. Es bleibt zu hoffen, dass die Ideen von Frau Frommeyer aufgegriffen, die deutsche Sprachgrenze überwunden und bei den Regelwerksdiskussionen und Formatentwicklungen international berücksichtigt werden."

- 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").
