- 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.
- 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."

- Rez. in: Knowledge organization 34(2007) no.1, S.58-60 (P. Buizza): "This Nuovo soggettario is the first sign of subject indexing renewal in Italy. Italian subject indexing has been based until now on Soggettario per i cataloghi delle biblioteche italiane (Firenze, 1956), a list of preferred terms and see references, with suitable hierarchical subdivisions and cross references, derived from the subject catalogue of the National Library in Florence (BNCF). New headings later used in Bibliografia nazionale italiana (BNI) were added without references, nor indeed with any real maintenance. Systematic instructions on how to combine the terms are lacking: the indexer using this instrument is obliged to infer the order of terms absent from the lists by consulting analogous entries. Italian libraries are suffering from the limits of this subject catalogue: vocabulary is inadequate, obsolete and inconsistent, the syndetic structure incomplete and inaccurate, and the syntax ill-defined, poorly explained and unable to reflect complex subjects. In the nineties, the Subject Indexing Research Group (Gruppo di ricerca sull'indicizzazione per soggetto, GRIS) of the AIB (Italian Library Association) developed the indexing theory and some principles of PRECIS and drew up guidelines based on consistent principles for vocabulary, semantic relationships and subject string construction, the latter according to role syntax (Guida 1997). In overhauling the Soggettario, the National Library in Florence aimed at a comprehensive indexing system. (A report on the method and evolution of the work has been published in Knowledge Organization (Lucarelli 2005), while the feasibility study is available in Italian (Per un nuovo Soggettario 2002). Any usable terms from the old Soggettario will be transferred to the new system, while taking into consideration international norms and interlinguistic compatibility, as well as applications outside the immediate library context. The terms will be accessible via a suitable OPAC operating on the most advanced software.
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.
Now BNI is beginning to use the new language, pointing the way for the adoption of Nuovo soggettario in Italian libraries: a difficult challenge whose success is not assured. To name only one issue: including all fields of study requires particular care in treating terms with different specialized meanings; cooperation of other libraries and institutions is foreseen. At the same time, efforts are being made to assure the system's interoperability outside the library world. It is clear that a great commitment is required. "Too complex a system!" say the naysayers. "Only at the beginning," the proponents reply. The new system goes against the mainstream, compared with the imitation of the easy way offered by search engines - but we know that they must enrich their devices to improve quality, just repeating the work on semantic and syntactic relationships that leads formal expressions to the meanings they are intended to communicate - and also compared with research to create automated devices supporting human work, for the need to simplify cataloguing. Here AI is not involved, but automation is widely used to facilitate and to support the conscious work of indexers guided by rules as clear as possible. The advantage of Nuovo soggettario is its combination of a thesaurus (a much-appreciated tool used across the world) with the equally widespread technique of subject-string construction, which is to say: the rational and predictable combination of the terms used. The appearance of this original, unparalleled working model may well be a great occasion in the international development of indexing, as, on one hand, the Nuovo soggettario uses a recognized tool (the thesaurus) and, on the other, by permitting both pre-coordination and post-coordination, it attempts to overcome the fragmentation of increasingly complex and specialized subjects into isolated, single-term descriptors. This is a serious proposition that merits consideration from both theoretical and practical points of view - and outside Italy, too."

- Rez. in: KO 35(2008) no.1, S.55-58 (M.P. Satija): "The Sears List, first published in 1923, has survived times of destabilizing changes while keeping reasonable continuity with the past. Dr. Joseph Miller, at the helm since 1992 and the longest-serving editor in the eighty-four years of the List's existence, first edited the 15th edition of the Sears (1994). Over the years, the Sears has achieved more than it had hoped for: ever-increasing use the world over. In fact, the turbulent progress of media and information theories has forced the Sears to keep up with the changing times. Knowledge organization is a shifting sand in the electronic era. Vast and varied changes generate not only new information, but also new terms and phrases. It is trite to say that the electronic media have transformed the way in which we access information and knowledge. The new edition of the Sears has absorbed these changes to reflect the times. The 19th edition, released in May 2007, has about 440 new headings, to bring the new total to over 8000 headings, which keeps the growth rate at five percent. Newly-added headings generally fall into one of two categories: a) headings for the new and current subjects and b) headings previously missed. A few more have been modified. New editions are produced regularly to: - incorporate terms for new subjects, - restructure the form of old headings to suit the changing information needs and informationseeking behaviour of the users, - add new terms to old subject headings to reflect current usage, - delete the obsolete subjects, - forge new relations between subjects and their terms. Two major areas of new additions are in the fields of Islam, as might be expected, and the graphic novel- the latter has thirty headings perhaps drawn from the WilsonWeb Database on Graphic Novels Core Collection. ... The lapses are minor and could be forgiven; they in no way detract from this continuously-expanding and well-established tool for subject-cataloguing in small and medium libraries. The handy List and its lucid introduction make Sears an excellent and convenient tool for teaching subject headings' use and principles, as well as methods of vocabulary control. With its glossy and flowery cover, clear typeface and high production standards, the new edition is particularly welcome."
