The guide Nuovo soggettario was presented on February 8' 2007 at a one-day seminar in the Palazzo Vecchio, Florence, in front of some 500 spellbound people. The Nuovo soggettario comes in two parts: the guide in book-form and an accompanying CD-ROM, by way of which a prototype of the thesaurus may be accessed on the Internet. In the former, rules are stated; the latter contains a pdf version of the guide and the first installment of the controlled vocabulary, which is to be further enriched and refined. Syntactic instructions (general application guidelines, as well as special annotations of particular terms) and the compiled subject strings file have yet to be added. The essentials of the new system are: 1) an analytic-synthetic approach, 2) use of terms (units of controlled vocabulary) and subject strings (which represent subjects by combining terms in linear order to form syntactic relationships), instead of main headings and subdivisions, 3) specificity of terms and strings, with a view to the co-extension of subject string and subject matter and 4) a clear distinction between semantic and syntactic relationships, with full control of them both. Basic features of the vocabulary include the uniformity and univocality of terms and thesaural management of a priori (semantic) relationships. Starting from its definition, each term can be categorially analyzed: four macro-categories are represented (agents, action, things, time), for which there are subcategories called facets (e.g., for actions: activities, disciplines, processes), which in turn have sub-facets. Morphological instructions conform to national and international standards, including BS 8723, ANSI/ NISO Z39.19 and the IFLA draft of Guidelines for multilingual thesauri, even for syntactic factorization. Different kinds of semantic relationships are represented thoroughly, and particular attention is paid to poly-hierarchies, which are used only in moderation: both top terms must actually be relevant. Node labels are used to specify the principle of division applied. Instance relationships are also used.
Thesaurus software is based on AgroVoc (http:// www.fao.org/aims/ag_intro.htm) provided by the FAO, but in modified form. Many searching options and contextualization within the full hierarchies are possible, so that the choice of morphology and syntax of terms and strings is made easier by the complete overview of semantic relationships. New controlled terms will be available soon, thanks to the work in progress - there are now 13,000 terms, of which 40 percent are non-preferred. In three months, free Internet access by CD-ROM will cease and a subscription will be needed. The digital version of old Soggettario and the corresponding unstructured lists of headings adopted in 1956-1985 are accessible together with the thesaurus, so that the whole vocabulary, old and new, will be at the fingertips of the indexer, who is forced to work with both tools during this transition period. In the future, it will be possible to integrate the thesaurus into library OPACs. The two parts form a very consistent and detailed resource. The guide is filled with examples; the accurate, clearly-expressed and consistent instructions are further enhanced by good use of fonts and type size, facilitating reading. The thesaurus is simple and quick to use, very rich, albeit only a prototype; see, for instance, a list of DDC numbers and related terms with their category and facet, and then entries, hierarchies and so on, and the capacity of the structure to show organized knowledge. The excellent outcome of a demanding experimentation, the intended guide welcomes in a new era of subject indexing in Italy and is highly recommended. The new method has been designed to be easily teachable to new and experimented indexers.

Rez. in: ZfBB 50(2003) H.5, S.295-297 (E. Scheven):"In ihrem Buch »Zeitbegriffe und Zeitcodierungen in allgemeinbibliographischen Datenbanken« entwickelt die Autorin ein theoretisches Modell für ein Zeitretrieval in allgemeinbibliografischen Datenbanken. Dafür untersucht sie die Verwendung von Zeitbegriffen (Epochenbezeichnungen, historiografischen Begriffen) und Zeitcodierungen (Jahreszahlen, Datumsangaben) bei der Indexierung von Dokumenten in allgemeinbibliografischen Datenbanken und deren Retrievalmöglichkeiten. Durch Globalisierung und Internet ist der Zugang zu den Katalogen unterschiedlichster lnstitutionen weit überdie Landesgrenzen hinaus möglich geworden. Dadurch ist der Zwang zur Standardisierung der bibliothekarischen Regeln weltweit verschärft, um Daten-Interoperabilität zu gewährleisten. Hauptziel der Sacherschließung muss immer die optimale Befriedigung der Benutzerbedürfnisse sein. - Kompetente Einführung - Nach einer kurzen geschichtlichen Darstellung der Zeitrechnung an sich und der bibliothekarischen Regelentwicklung wendet sich die Autorin den wichtigsten Sacherschließungswerkzeugen der westlichen WeIt zu, zum einen den beiden internationalen Universalklassifikationen, DDC und UDK, und zum anderen den drei Schlagwortsystemen LCSH, Rameau und SWD,wobei sieden Schwerpunkt auf die verbalen Sacherschließungssysteme legt. LCSH, Rameau und SWD mit RSWK werden kompetent und ausführlich in 164 von 316 Seiten mit ihrer Entwicklungsgeschichte und ihren Unterschieden dargestellt. Jutta Frommeyer ist hier eine gute vergleichende Einführung in die großen verbalen Sacherschließungssysteme gelungen und zwar nicht nur für Anfänger, sondern auch für praxis-erfahrene Sacherschließer. Die Darstellung von Zeitaspekten nach LCSH kann nach sechs verschiedenen Varianten erfolgen. Es gibt keine allgemeinen subdivisions für Zeitangaben. Rameau stimmt in seiner Struktur mit den LCSH überein, weicht aber bei der Indexierung bezüglich der subdivisions von den LCSH ab. Rameau hat eine allgemein zu verwendende Liste (subdivision) mit ca. 40 Unterteilungen für den Zeitaspekt. Nach RSWK wird der Zeitaspekt durch so genannte Zeitschlagwörter wiedergegeben, die wie auch bestimmte Formalschlagwörter durch Jahreszahlen erweitert werden können. Der im Dokument behandelte Zeitabschnitt wird für die Beschlagwortung herangezogen. Vorgegebene Zeituntergliederungen für bestimmte Themenbereiche wie bei LCSH und Rameau gibt es bei RSWK nicht. Zwischen den Schlagwortsystemen gibt es unterschiedliche Indexierungsregeln, wann ein Zeitschlagwort benutzt werden soll oder nicht.
