    "Unsere Sitzung fand diesmal am 13. 9. 2005 in Bozen im Rahmen der ODOK statt. Es waren daher auch viele interessierte Südtiroler und italienische Sacherschließungskollegen/-innen zu Gast. Eine der beiden Konferenzsprachen war Englisch, und so konnten wir Mehrsprachigkeit, das Thema unserer Sitzung und der beiden Gastvorträge, gleich selbst praktizieren. Patrice LANDRY, der Leiter der Sacherschließung an derSLB in Bern, der seit kurzem den Vorsitz der IFLA-Sektion "Classification and Indexing" und der Arbeitsgruppe "Guidelines for subject access for national bibliographic agencies" übernommen hatte, referierte über den jüngsten Stand des Projekts MACS (Multilingual Access to Subjects) und ließ uns am Nachmittag in seinem Workshop hinter die Kulissen der bereits mit echten Titeldaten operierenden Suchoberfläche blicken. Er zeigte die verschiedenen Recherche- und Editier-Funktionen im Management Linking System und brachte Beispiele für die kooperative Bearbeitung an einigen Datensätzen der bisher bereits miteinander verzahnten Normdateien SWD, LCSH und RAMEAU. Schließlich eröffnete er Ausblicke auf die künftige Einbindung weiterer Sprachen, etwa des Italienischen durch den Soggetario und auf die Anreicherung der Daten, etwa mit DDC-Notationen durch die Nähe zum DDB-Projekt "CrissCross". Federica PARADISI, die in der Sacherschließungsabteilung der BNC in Florenz sowohl für die italienische Übersetzung der DDC und deren Anwendung in ganz Italien als auch für die Überarbeitung des seit 1956 existierenden italienischen Wortschatzes für die verbale Erschließung und für dessen Aufbereitung zu einer modernen, bald auch elektronischen Normdatei zuständig ist und an der Erstellung der italienischen Nationalbibliografie mitwirkt, hat zuletzt gemeinsam mit Anna Lucarelli den Prototyp des "Nuovo Soggetario" erarbeitet und stellte dieses umfangreiche Projekt vor. Der von ihr skizzierte Zeitplan gibt Anlass zur Hoffnung, dass MACS für die Auffindung beschlagworteter Literatur in Bibliothekskatalogen schon in einem Jahr um einen sprachlichen Zugang reicher sein könnte. Beide Gastreferenten/-innen standen dem Auditorium im Anschluss an die Präsentationen für Fragen zur Verfügung, und die neuen fachlichen Kontakte vertieften sich in den Pausengesprächen noch mehr. Vor der Führung durch die Dewey-Ausstellung im Lichthof der UB Bozen demonstrierte Margit SANDNER zum Abschluss dieses multilingualen Sacherschließungsnachmittags mit einigen Beispielen in deutscherSprache die Suchfunktionen in den beiden Webversionen von DDC Deutsch MelvilSearch (für OPACs) und MelvilClass (für das Klassifizieren) und kündigte an, dass ab Oktober bis Jahresende kostenlose Testaccounts vergeben werden. Wer daran interessiert ist, diese deutschsprachigen Webtools bereits auszuprobieren, wendet sich am besten direkt an Herrn Dr. Lars Svensson in Der Deutschen Bibliothek in Frankfurt: svensson@dbf.ddb.de. Die ab Jänner 2006 gültigen Lizenzbedingungen für "Melvil" entnehmen Sie bitte: http//www.ddc-deutsch.de/licence-melvil.html Noch zwei aktuelle Hinweise: - Informationstag der Arbeitsstelle für Standardisierung (DDB) über aktuelle Tendenzen in Sachen Regelwerke f. Formal- und Sacherschließung, Formate, Normdateien und Datentausch am 15. November in Wien. - Aufsatz über die Zukunft der SWD von Esther Scheven (BD 2005, H. 6, S. 748-773), in dem u. a. auch auf unsere seinerzeitige KofSE-Studie: Schlagwort "Benutzerforschung" ... (VÖB-Mitt. 1997, H. 3-4, S. 28-49) rekurriert wird."

    Abstract
    This classified critical bibliography continues the work initiated by Monika Kirtland and Pauline Cochrane, and furthered by Steven Blake Shubert. Kirtland and Cochrane published a bibliography surveying the literature critical of LCSH from 1944-1979 titled "Critical Views of LCSH - Library of Congress Subject Headings, A Bibliographic and Bibliometric Essay." Shubert analyzed another decade of literature in his article titled "Critical Views of LCSH-Ten Years Later: A Bibliographic Essay." This current bibliography compiles the next twelve years of critical literature from 1990-2001. Persistent concerns of the past fifty-seven years include inadequate syndetic structure, currency or bias of the headings, and lack of specificity in the subject heading list. New developments and research are in the areas of subdivisions, mapping, indexer inconsistency, and post-coordination. LCSH must become more flexible and easier to use in order to increase its scalability and interoperability as an online subject searching tool.

    Rez. in: KO 38(2011) no.4, S.360-361 (M.P. Satija): "The 20th edition of the celebrated Sears List (1sted.1923) published in June 2010 sets a new cycle of three year revision. Earlier it was three and a half years to synchronize with the publication of the new edition of the Abridged Dewey revised after every seven years. In the days of constantly updated WebDewey, it is no more a constraint. For the first time Sears List has been released simultaneously in online database format accessible to licensed subscribers. Responding to the environmental changes the basic edition is the online one whose content is designed in MARC authority. Print edition is now a derivative of the MARC data. The editors keep tabs on the changing information seeking behavior of users and how OPACs are accessed; yet the editors or the publishers never discuss the mechanisms of designing a new edition. The new edition features more than 300 new subject headings suggested by librarians from different types of libraries, vendors of bibliographic records, indexers and subject specialists at the H.W. Wilson Company. Every new edition incorporates advances in vocabulary control, changing approaches of library users for subject access and even in the worldwide use of the English language. Each edition of the Sears List strengthens and continues the policies and consolidates the reforms that began with the 15th edition (1994). It is indeed an era of innovations in Sears. The latest knowledge from information science and information seeking behavior has been deployed to modernize the internal structure and grammar of the Sears List. Continuing adaptation constitutes the key to its success and popularity in the shifting sands of the information-seeking behavior of users. But the List is still a living manifestation of the principles of subject cataloguing put forth by C.A. Cutter (1837-1903).
    . . . To summarize, as usual the List continues to provide complete guidance for the subject cataloguers for the maintenance of catalogues, for addition of new headings, and revision of the old ones. Its Introduction is clear and well illustrated, so much so that not only it is an illustrated operational manual to the Sears but also a concise textbook to teach principles and theory of the subject headings. Due to its affordable price and portability it is used to teach basics of subject headings in first year of Knowledge Organization courses. It also acts as an excellent and easy index to the DDC (Weihs 2004). The new edition should be welcome both for subject cataloguers and for teachers of subject cataloguing work."

    Abstract
    As an Italian chapter of ISKO has recently been reorganized, I was kindly invited to Write a short report an current KO activities in our country. So, in the following, I will briefly illustrate the local situation of the various kinds of knowledge organization systems, as well as related developments and activities. I am grateful to Paola Capitani, Emanuela Casson, Michele Santoro, and Lorena Zuccolo for providing useful information to be included here.

    "Subject headings Many Italian libraries create subject headings for their catalogues, using as a reference guide the "Soggettario per i catalogui delle biblioteche italiane." This is basically a list of subject terms created by the Biblioteca nazionale centrale di Firenze (BNCF), first published in 1956 and later updated with various lists of new subject headings. Though the Soggettario is still the main available reference, librarians are generally aware that it is outdated in both vocabulary and structure, especially as it does not provide explicit principles and rules to create and combine subject headings. A research group, called the Gruppo di ricerca sull'indicizzazione per soggetto (GRIS), was founded in 1990. It was devoted to improving the principles and consistency of subject indexing. Its members have performed in depth investigations of the structure of subject headings, starting with the principles of facet analysis used in PRECIS and including original developments. Results of their work are coded into the Guida all'indicizzazione per soggetto, published in 1996 and available also online <http:// wwwaib.it/aib/commiss/gris/gulda.htm>. The GRIS guide does not concern vocabulary, but morphological and syntactical rules for choosing and combining terms according to a sound citation order, based an a "role scheme." Unfortunately, GRIS principles have been applied only in a small number of libraries, mainly in Tuscany, rohere most GRIS members are located. A new project is now attempting to blend the traditional authority of the Soggettario with the more advanced principles of GRIS. A working group has been formed with people from BNCF, GRIS, and others, to study the feasibility of a renewal of the Soggettario. The group produced a report book in 2002, specifying the desirable features of the new system, and is at present searching for grants to implement it.
    Terminology and thesauri BNCF is also involved in a working group collecting information an online terminological resources <http://wwwindire.it/websemantico>. The group is headed by Paola Capitani, and has organized several roundtables an terminology in special domains, such as economy, fashion, law, and education. Thesauri are generally poorly known and used in Italy, although there are significant exceptions: among faceted systems we can mention the "Thesauro italiano di sociologia," published in 1999, and the "Thesaurus regionale toscano," as well as specialized an social sciences including a general outline, available both in print (1996) and online <http:// www regione.toscana.it/ius/ns-thesaurus/>. Classification systems The Dewey Decimal Classification (DDC) is by far the most widespread classification scheme in Italian libraries. A working group, coordinated by Luigi Crocetti, regularly translates the new editions of DDC manuals, and gives refresher courses an it for librarians. BNCF makes DDC numbers for bibliographical records both of its own catalogue, and of the national bibliography (= Bibliografia nazionale italiana: BNI), which is available for other libraries in a CD-ROM edition. A very large number of public libraries use DDC for their shelfmarks, so that users are accustomed to it. This situation is different from other European countries, e.g., Spain where UDC is widespread."

    Although the rules for descriptive cataloging have been recodified twice in the past twenty years, there never has been any kind of comprehensive theoretical code for subject headings, despite some suggestions for a code over the years. This essay explains the need for a code, provides historical background, and presents some broad proposals as to the philosophy, structure, and form of the code and what the code should cover. Included is the relation between the proposed code and the Library of Congress' 1984 Subject Cataloging Manual.

    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

    Abstract
    The system is available both in print and online versions. Names a few new subject headings in areas like science, technology, engineering and medicine (STEM). In this edition, there are a total of 1,600 new headings making it a total of 12,000+ preferred headings meant for subject access in small and medium sized libraries. This unprecedented increase of about 1,600 headings is mostly due the complete incorporation of the Canadian Sears last published independently in 2006. Also critically examines inconsistencies in a few headings. Concludes to say the new edition in resplendent, hard binding maintains its stellar reputation of a handy list of general subject headings both for applications and a teaching resource.

    Abstract
    Library of Congress Subject Headings (LCSH), a system originally designed as a tool for subject access to the Library's own collection in the late nineteenth century, has become, in the course of the last century, the main subject retrieval tool in library catalogs throughout the United States and in many other countries. It is one of the largest non-specialized controlled vocabularies in the world. As LCSH enters a new century, it faces an information environment that has undergone vast changes from what had prevailed when LCSH began, or, indeed, from its state in the early days of the online age. In order to continue its mission and to be useful in spheres outside library catalogs as well, LCSH must adapt to the multifarious environment. One possible approach is to adopt a series of scalable and flexible syntax and application rules to meet the needs of different user communities

    Abstract
    The Nuovo soggettario, the official Italian subject indexing system edited by the National Central Library of Florence, is made up of interactive components, the core of which is a general thesaurus and some rules of a conventional syntax for subject string construction. The Nuovo soggettario Thesaurus is in compliance with ISO 25964: 2011-2013, IFLA LRM, and FAIR principle (findability, accessibility, interoperability, and reusability). Its open data are available in the Zthes, MARC21, and in SKOS formats and allow for interoperability with l library, archive, and museum databases. The Thesaurus's macrostructure is organized into four fundamental macro-categories, thirteen categories, and facets. The facets allow for the orderly development of hierarchies, thereby limiting polyhierarchies and promoting the grouping of homogenous concepts. This paper addresses the main features and peculiarities which have characterized the consistent development of this categorical structure and its effects on the syntactic sphere in a predominantly pre-coordinated usage context.

    Abstract
    Evaluative and comparative studies of catalog data have tended to focus on methods that are labor intensive, demand expertise, and can examine only a limited number of records. This study explores an alternative approach to gathering and analyzing catalog data, focusing on the currency and consistency of controlled headings. The resulting data provide insight into libraries' use of changed headings and their success in maintaining currency and consistency, and the systems needed to support the current pace of heading changes.

    Abstract
    Structured abstracts are abstracts which include subheadings such as: background, aims, participants methods and results. These are rapidly replacing traditional abstracts in medical periodicals, but the number and detail of the subheadings used varies, and there is a range of different typographic settings. Reviews a number of studies designed to investigate readers' preferences for different typographic settings and layout. Over 400 readers took part in the study: students; postgraduates; research workers and academics in the social sciences. The most preferred version emerged from the last of 3 studies and 2 additional studies were then carried out to determine preferences for the overall position and layout of this most preferred version on a A4 page. The most preferred version for the setting of the subheadings are printed in bold capital letters

    Abstract
    Form subdivisions have always been an important part of the Library of Congress Subject Headings. However, when the MARC format was developed, no separate subfield code to identify form subdivisions was defined. Form and topical subdivisions were both included within a general subdivision category. In 1995, the USMARC Advisory Group approved a proposal defining subfield v for form subdivisions, and in 1999 the Library of Congress (LC) began identifying form subdivisions with the new code. However, there are millions of older bibliographic records lacking the explicit form subdivision coding. Identifying form subdivisions retrospectively is not a simple task. An algorithmic method was developed to identify form subdivisions coded as general subdivisions. The algorithm was used to identify 2,563 unique form subdivisions or combinations of form subdivisions in OCLC's WorldCat. The algorithm proved to be highly accurate with an error rate estimated to be less than 0.1%. The observed usage of the form subdivisions was highly skewed with the 100 most used form subdivisions or combinations of subdivisions accounting for 90% of the assignments.

    Abstract
    Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

    Abstract
    Purpose - This paper aims to discuss some long-standing issues of the development of a subject heading language as pre- or postcoordinated. Design/methodology/approach - In a review of literature on pre- and postcoordination and user behaviour, 20 criteria originally discussed by Svenonius are considered. Findings - The advantages and disadvantages of pre- and postcoordinated systems are on a very similar level. Most subject heading languages developed recently are precoordinated. They all require investments in highly skilled intellectual work, and are therefore expensive and difficult to maintain. Postcoordinated systems seem to have more advantages for information providers, but less for users. However, most of these disadvantages could be overcome by known information retrieval models and techniques. Research limitations/implications - The criteria originally discussed by Svenonius are difficult to evaluate in an exact manner. Some of them are also irrelevant because of changes in information retrieval systems. Practical implications - It was found that the decision on whether to use a pre- or postcoordinated system cannot be taken independent of consideration of the subject authority file and the functions of an information retrieval system, which should support users on one hand and information providers and indexers on the other. Originality/value - This literature review brings together some findings that have not been considered together previously.

    Abstract
    The Nuovo Soggettario is a subject indexing system edited by the Biblioteca Nazionale Centrale di Firenze. It was presented to librarians from across Italy on 8 February 2007 in Florence as a new edition of the Soggettario (1956), and it has become the official Italian subject indexing tool. This system is made up of two individual and interactive components: the general thesaurus, accessible on the web since 2007 and the rules of a conventional syntax for the construction of subject strings. The Nuovo soggettario thesaurus has grown significantly in terms of terminology and connections with other knowledge organization tools (e.g., encyclopedias, dictionaries, resources of archives and museums, and other information data sets), offering the users the possibility to browse through documents, books, objects, photographs, etc. The conversion of the Nuovo soggettario thesaurus into formats suitable for the semantic web and linked data world improves its function as an interlinking hub for direct searching and for organizing content by different professional communities. Thanks to structured data and the SKOS format, the Nuovo soggettario thesaurus is published on the Data Hub platform, thus giving broad visibility to the BNCF and its precious patrimony.

    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.
    An entry is structured so as to present all the essential elements of the indexing system. For each term are given: category, facet, related terms, Dewey interdisciplinary class number and, if necessary; definition or scope notes. Sources used are referenced (an appendix in the book lists those used in the current work). Historical notes indicate whenever a change of term has occurred, thus smoothing the transition from the old lists. In chapter 5, the longest one, detailed instructions with practical examples show how to create entries and how to relate terms; upper relationships must always be complete, right up to the top term, whereas hierarchies of related terms not yet fully developed may remain unfinished. Subject string construction consists in a double operation: analysis and synthesis. The former is the analysis of logical functions performed by single concepts in the definition of the subject (e.g., transitive actions, object, agent, etc.) or in syntactic relationships (transitive relationships and belonging relationship), so that each term for those concepts is assigned its role (e.g., key concept, transitive element, agent, instrument, etc.) in the subject string, where the core is distinct from the complementary roles (e.g., place, time, form, etc.). Synthesis is based on a scheme of nuclear and complementary roles, and citation order follows agreed-upon principles of one-to-one relationships and logical dependence. There is no standard citation order based on facets, in a categorial logic, but a flexible one, although thorough. For example, it is possible for a time term (subdivision) to precede an action term, when the former is related to the latter as the object of action: "Arazzi - Sec. 16.-17. - Restauro" [Tapestry - 16th-17th century - Restoration] (p. 126). So, even with more complex subjects, it is possible to produce perfectly readable strings covering the whole of the subject matter without splitting it into two incomplete and complementary headings. To this end, some unusual connectives are adopted, giving the strings a more discursive style.
    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.
    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."
