- 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
- 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.

- Abstract
- Over the last ten years, the Servizio Bibliotecario Nazionale (SBN) has become the largest Italian network of bibliographic services. The creation of the SBN Index database and its growth through shared cataloging were the focus of attention during the early phase, and for years, discussion was limited to questions of author cataloging and bibliographic description. Subject cataloging was excluded from the cooperative activity of the member libraries. In 1990 the Working Group on Subject Headings and Classes was established to examine this situation. First, a partial solution was found, to permit the launch of the network itself. This was followed, several years later, by the development of the SBN OPAC and the creation of the file of subject headings and classes in the SBN Index. From an operational perspective, the choice was made to forego managing the subject headings file in accordance with shared cataloging principles, with mixed results. In order for the subject file to have broader coverage and to further encourage cooperative subject cataloging, the SBN Index Development Program, in which the Istituto Centrale per il Catalogo Unico delle Biblioteche Italiane (ICCU) has been engaged for about two years, aims at enriching services of the database and opening up new and diversified types of usage. Almost simultaneously the Biblioteca Nazionale Centrale di Firenze (BNCF) initiated a feasibility study on the revision of the Soggettario delle biblioteche italiane (List of Subject Headings in Italian Libraries) for the catalogs of Italian libraries. Both the BNCF and the ICCU share the goal of building a new, consistent vocabulary for documentation of subject matter.

- Abstract
- Moving to a fully faceted syntax would resolve three problems facing Library of Congress Subject Headings (LCSH): 1. Inconsistent syntax rules; 2. Inability to create headings that are coextensive with the topic of a work; and 3. Lack of effective displays for long lists of subdivisions under a single subject heading in OPACs and similar electronic displays. The authors advocate a fully faceted syntax using the facets of a modern faceted library classification (The Bliss Bibliographic Classification, 2d ed.). They demonstrate how this might be accomplished so as to integrate the new syntax with existing headings.

- In 1986 Libraries Unlimited published Cochrane's book, Improving LCSH for Use in Online Catalogs; Exercises for Self-Help with a Selection of Background Readings. This was preceded in 1981 by an ERIC publication (ED 208 900) by Cochrane, with Monika Kirtland Bibliographic and Bibliometric Essay which documented critical views of LCSH and an analysis of vocabulary control in LCSH (parts of which were published in Cataloging & Classification Quarterly' 1(2/3) (1982), 71-94). Three features of LCSH will be re-examined to check on progress since the time of these earlier publications: notes, structure of relationships between headings in the list, and links between Library of Congress classification numbers and LCSH or other vocabularies

- Abstract
- Authority control of Spanish-language subject headings is described, with a special focus on Mexico. Efforts currently underway in Colombia, Chile, Spain and Mexico, although they share the same language, are somewhat lacking in standardization and cooperation among countries. In the absence of a national authority for bibliographic control in Mexico, a group of university libraries has initiated a cooperative project to build in the near future a national file of Spanish subject headings for the Social Sciences. The project, based upon the experience and rich collections of El Colegio de Mexico, has attracted support from the U.S. Library of Congress and is being partially financed by the U.S.-Mexican Fund for Culture (sponsored by the Rockefeller and Bancomer Foundations). The paper mentions some of the difficulties found in translating LCSH, which is the main resource for the project. These difficulties can include semantics, syndetic structure, or pragmatic problems; most have been solved by supplementing the LCSH with Spanish-language subject heading lists or thesauri

- "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."
