- Abstract
- We aim to trace the scenario of the use of controlled vocabularies as tools of research and work in the scope of representation and retrieval of information in institutions that have archival collections, in order to highlight the need for greater emphasis on the subject of representation of archival information in the academic field, increasing the visibility for the study and analysis of the collections in question and their contents, relevant to the information society. We investigate the current scenario of the use of controlled vocabularies in the archival collections of Rio de Janeiro, the theoretical-methodological changes arising from the impacts of information technologies on analysis, representation, such as classification and indexing, content retrieval, information needs in the contemporary world. The representation of information is associated with classification and retrieval of information to the organization of knowledge in information science. There is a gap in the archival area regarding the expression representation of information from the description of the nineteenth century. As for the theoretical-methodological aspect, there was a theoretical survey of the representation of information in publications in the interdisciplinary areas; as to the op-erational methodology, questionnaires were applied to information agencies on the use of controlled vocabularies, in relation to the treatment of information in archival collections. We conclude by demonstrating the importance of adopting the concept of information representation in archives, using controlled vocabularies associated with new information technologies and informational ecology, consolidating the area as a scientific and interdisciplinary field for information science.

- Abstract
- More and more users index everything on their own in the web 2.0. There are services for links, videos, pictures, books, encyclopaedic articles and scientific articles. All these services are library independent. But must that really be? Can't libraries help with their experience and tools to make user indexing better? On the experience of a project from German language Wikipedia together with the German person authority files (Personen Namen Datei - PND) located at German National Library (Deutsche Nationalbibliothek) I would like to show what is possible. How users can and will use the authority files, if we let them. We will take a look how the project worked and what we can learn for future projects. Conclusions - Authority files can have a role in the web 2.0 - there must be an open interface/ service for retrieval - everything that is indexed on the net with authority files can be easy integrated in a federated search - O'Reilly: You have to found ways that your data get more important that more it will be used

- Abstract
- Authority control is a standard practice in the library community that provides consistent, unique, and unambiguous reference to entities such as persons, places, concepts, etc. The ideal way of referring to authority records through unique identifiers is in line with the current linked data principle. When presenting a bibliographic record, the linked authority records are expanded with the authoritative information. This way, any update in the authority records will not affect the indexing of the bibliographic records. The structural information in the authority files can also be leveraged to expand the user's query to retrieve bibliographic records associated with all the variations, narrower terms or related terms. However, in many digital libraries, especially largescale aggregations such as WorldCat and Europeana, name strings are often used instead of authority record identifiers. This is also partly due to the lack of global authority records that are valid across countries and cultural heritage domains. But even when there are global authority systems, they are not applied at scale. For example, in WorldCat, only 15% of the records have DDC and 3% have UDC codes; less than 40% of the records have one or more topical terms catalogued in the 650 MARC field, many of which are too general (such as "sports" or "literature") to be useful for retrieving bibliographic records. Therefore, when a user query is based on a Dewey code, the results usually have high precision but the recall is much lower than it should be; and, a search on a general topical term returns millions of hits without being even complete. All these practices make it difficult to leverage the key benefits of authority files. This is also true for authority files that have been transformed into linked data and enriched with mapping information. There are practical reasons for using name strings instead of identifiers. One is the indexing and query response. The future infrastructure design should take the performance into account while embracing the benefit of linking instead of copying, without introducing extra complexity to users. Notwithstanding all the restrictions, we argue that largescale aggregations also bring new opportunities for better exploiting the benefits of authority records. It is possible to use machine learning techniques to automatically link bibliographic records to authority records based on the manual input of cataloguers. Text mining and visualization techniques can offer a contextual view of authority records, which in return can be used to retrieve missing or mis-catalogued records. In this talk, we will describe such opportunities in more detail.

- Abstract
- The development of the National Authority File of Geographic Names has been carried out by the Russian State Library (RSL) since 2003 in the framework of the Federal program called "Russian culture (2001-2005)". The file will be a part of the complex of the authority files for the network of Russian libraries (LIBNET). Its aim is to provide usage of standardized Russian geographic names in the library practice (cataloguing of the documents and information retrieval), established officially on the federal level. The Russian National Authority File for Geographical Names is identified by the code "rugeo" in the MARC 21 format for use in subfield $2 for subject/index term sources.

- Abstract
- A variety of information communities have developed metadata schemes to meet the needs of their own users. The ability of libraries to incorporate and use multiple metadata schemes in current library systems will depend on the compatibility of imported data with existing catalog data. Authority control will play an important role in metadata interoperability. In this article, I discuss factors for successful authority control in current library catalogs, which include operation in a well-defined and bounded universe, application of principles and standard practices to access point creation, reference to authoritative lists, and bibliographic record creation by highly trained individuals. Metadata characteristics and environmental models are examined and the likelihood of successful authority control is explored for a variety of metadata environments.

- Abstract
- Defines authority control and vocabulary control and their place and utility in modern cataloguing. Discusses authority records and authority files and the use and purposes of each. Describes the creation of authority records and the sources from which authority data is collected. Discusses "metadata" schemes and their manifold and manifest inadequacies; points out the relationship of the Dublin Core to the MARC family of standards and the fact that both are framework standards-the first simplistic and naïve, the second complex and nuanced. Defines precision and recall as desiderata in indexing and retrieval schemes and relates them to authority control in catalogues. Discusses the problems involved in cataloguing electronic documents and resources and proposes an international program under the Universal Bibliographic Control (UBC) umbrella, using an international code of descriptive cataloguing, and based on an international name authority file. Calls for urgent action on these proposals.

- Abstract
- Catalogers have become interdependent in their pursuit to provide bibliographic control and access. This interdependency has brought with it the need for greater agreement in applying common cataloging policies and rules. The expanded application of AACR2 (Anglo-American Cataloguing Rules) is fostering greater uniformity in the provision of bibliographic description and access. The rules have been translated into numerous languages and used in European, Middle Eastern, and Latin American countries. Cataloging committees and individual libraries in Europe and South Africa have expressed strong interest in adopting, adapting, or aligning with AACR2. PCC (Program for Cooperative Cataloguing) is one of the most successful cooperative cataloging efforts and has a considerable international component, which encourages the use of AACR, LCSH (Library of Congress Subject Headings), and MARC. AACR2 is successful on an international level because it is based in internationally developed standards, including ISBDs and the Paris Principles. ISBDs (International Standard Bibliographic Description) and the Functional Requirements for Bibliographic Records are examples of the contributions that IFLA (International Federation of Library Associations and Institutions) has made to the internationalization of cataloging. IFLA sponsored the international conference that resulted in the Paris Principles as well as subsequent projects to craft international policy in relation to uniform headings for persons, corporate bodies, and titles.

- Abstract
- The Library of Congress Subject Headings schema (LCSH) is the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, 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. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST (Faceted Application of Subject Terminology) headings is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains compatibility with LCSH--any valid Library of Congress subject heading can be converted to FAST headings.

- Abstract
- A classification scheme represents a powerful indexing and retrieval tool. Obsolete terminology and misalignment between widely used systems is key impediment to better use of classification. This paper looks into the issues caused by delay in the revision of UDC class of medical sciences and possible solutions. Following a short description of the Universal Decimal Classification (UDC) and of the National Library of Medicine (NLM) Classification, the author analyses the notations and captions included in 61 class of the UDC Summary. All the classes, subclasses and special auxiliary subdivisions are covered in order to find compatible notations between both schemes, out-of-date vocabulary and out-of-date subdivisions of UDC. As a result of this study and in light of the most recent developments in medical sciences, one subdivision is questioned and several vocabulary expressions included in the caption fields are proposed to be changed or updated.

- Abstract
- This paper compares one hundred corporate names listed in the National Authority File (LC NAF) on OCLC with the corporate names listed on official corporate web pages collected between October 1st and November 30th, 2001 in order to understand and evaluate their differences. Twenty five percent of corporate names found in the National Authority File are different from the form of corporate names found on official corporate web pages in this study. This creates a concern that users may not be finding everything issued by corporate bodies in library catalogs. Which form of corporate names should catalogers use as the authorized headings?

- Abstract
- Explicit authority control of works is essentially non-existent. Our catalogs are built on a principle of controlling headings, and primarily headings for names of authors. Our syndetic structure creates a spider's web of networked relationships among forms of headings, but it ends there, despite the potential richness of depth among bibliographic entities. Effective authority control of works could yield richness in the catalog that would enhance retrieval capabilities. Works are considered to constitute the intellectual content of informative artifacts that may be collected and ordered for retrieval. In a 1992 study the author examined a random sample of works drawn from the catalog of the Georgetown University Library. For each progenitor work, an instantiation network (also referred to as a bibliographic family) was constituted. A detailed analysis of the linkages that would be required for authority control of these networks is reviewed here. A new study is also presented, in which Library of Congress authority records for the works in this sample are sought and analyzed. Results demonstrate a near total lack of control, with only 5.6% of works for which authority records were found. From a sample of 410 works, of which nearly half have instantiation networks, only 23 works could be said to have implicit authority control. However, many instantiation networks are made up of successive derivations that can be implicitly linked through collocation. The difficult work of explicitly linking instantiations comes with title changes, translations, and containing relations. The empirical evidence in the present study suggests that explicit control of expressions will provide the best control over instantiation networks because it is instantiations such as translations, abridgments, and adaptations that require explicit linking.

- Abstract
- The costs of authority control are high and the information provided in authority files is often duplicated in separate bibliographic files. Librarians need to examine the compatibility of traditional methods of authority control with the advanced capabilities of current computer systems. This study investigates the actual use of the Library of Congress Name Authority File (LCNAF) by catalogers in an RLIN member library. Results show that some aspects of authority control could be expedited by changes in cataloging practice and search software.

- Abstract
- The project of the renewal of the Subject Headings for Italian Library Catalogues (Soggettario), financed by the National Central Library in Florence, proposes a pre-coordinated language, both analytic and synthetic, complying with international rules on vocabulary control and structure, based on category analysis of semantic relationships. It envisages a strict distinction between semantic relationships and syntactic ones, and bases its citation order of subject strings on the analysis model for logical relationships. Thanks to its features, the new Soggettario agrees both with the logic of Guidelines for Subject Authority and Reference Entries and of UNIMARC. Authorities, and with FRBR (Functional Requirements for Bibliographic Records). The rigorous structure of the thesaurus will facilitate the transfer of controlled terminology to lists or authority files and archives. The Italian National Bibliography (BNI) will have to play a leading role on the control of coherence of semantic access points. It will validate the strings created by other libraries and control their coherence according to the syntax rules envisaged in the new method.

- Abstract
- This paper discusses the basics of creating name authority records for Arabic personal names in accordance with Resource Description and Access instructions and Program for Cooperative Cataloging guidelines. A background into the use of romanization for non-Latin scripts in bibliographic and authority records is provided to establish the context. Issues with romanization that are particular to Arabic are addressed. Separate sections on modern and classical names provide an overview of the major challenges, and strategies to enhance discovery are outlined. The paper concludes with an examination of the possible benefits of identity management and other changes in the authority control landscape for names in non-Latin script.

- Abstract
- Before speaking about authority control in a multilingual environment, it is necessary to describe briefly the context in which this control is carried out. The electronic catalogue of the Russian State Library (RSL) contains more than 3 million records. Cataloguing with the use of the Aleph software and ??RC 21 has been carried out for this database since 2003. Other bibliographic records included in the electronic catalogue are received as a result of converting (1) bibliographic records from card catalogues, and (2) the bibliographic records created by RSL and other organizations with the use of other software and other formats. Up to 2003 the electronic catalogue included only records in Russian and in European languages. In 2003 we started cataloguing books and serials in the languages of the peoples of the Russian Federation and former union republics of the USSR. This year we are preparing for the description of documents in oriental languages. This "motley world" demands ordering and normalization of access points. Until 2003, two authority files were maintained in the RSL: the foreign and international organizations file and a file of "authors of special categories." Authority records were created in a format based on USMARC. In 2003 the authority control group was reorganized and its function widened. Now we are supposed to carry out the authority control of headings (controlled access points) in new bibliographic records by formation of authority records for these categories: - Names of persons, creators or objects of the work translated to Russian from other languages when in the document there is an original form of the name - Names of persons in which the forms of the names on the document differ from the form established for the system of catalogues at RSL - Such names of persons, as "authors of special categories" - Names of corporate bodies, Russian, foreign or international (creators or objects of the work), occurring in the system for the first time - Names of the corporate bodies, Russian, foreign or international reflected in authority records (machine-readable and traditional) if the form of the name on the document differs from the form established for the system of catalogues at RSL - The uniform titles of the Bible and its parts, anonymous classical works

- Abstract
- «Current proposals for the future of the Web describe the use of ontologies for making the Web more intelligent for machine and automatic processing. The Virtual International Authority File (VIAF) could be one of the basic building blocks to a »semantic web« when combined with other controlled vocabularies and authority files from such sources as abstracting and indexing services, archives, museums, publishers, etc. Libraries now have an opportunity to make a great contribution to this future and should help make this vision a reality.« This article gives a status report on the VIAF, a cooperative project of the Library of Congress, the Bibliotheque nationale de France, OCLC and the German National Library.

- Abstract
- Libraries are bridges between information and the library user in the context of information retrieval. Library users want to access information resources according to their topic. Therefore, it is important to create subject entries in bibliographic records. If subject added entries and their redirects are done correctly, it will make it easier for users to access the information they are looking for. In this article the collaborative studies and projects made in Turkey are being discussed.

- Abstract
- This paper examines the current state of authority control development in Spanish university repositories. As a decade has now gone by since the initiation of the first projects for institutional repositories in Spain, it would seem a suitable time to draw attention to authority control, an element of the first rank in evaluating the consistency and integrity of systems for recovering bibliographic information. The work is focused on examining the implementation of authorities in twenty-six Spanish university repositories, taking into account the information provided by the standardization experts working in them. The study considers the responses of the coordinators for these digital collections using a set of analytic criteria set out in the study. The handling of authorities in the group of university repositories studied may be described as uneven. Greater interest may be observed in controlling author entries, with laxer solutions for authority control of subjects. It suggests the need to establish effective policies for the management of authorities by means of cooperative efforts permitting the building up of corpora of entries for authorities that would aid the processes of cataloguing, metadata creation, and information retrieval in systems based on syntactic and semantic interoperability in which manual intervention should be minimal.

- Abstract
- Describes the experience of data conversion and migration at the libraries of the Home Office (HO) and the Dept. of the Environment (DoE), UK. Both HO and DoE libraries had changed from Anglo-American code cataloguing to AACR2 cataloguing in the mid-1970s. Both libraries were selective in identifying records for conversion initially to BLAISE-LOCAS. Conversion to integrated library systems from BLAISE-LOCAS MARC tapes produced problems in both libraries with location/holdings fields which were largely resolved at HO, but not resolved at DoE. HO experienced problems converting to a system with fixed field lengths. HO converted subject keywords to form a rudimentary, non-standard thesaurus which required the addition of Broader Term and Narrower Term to meet the challenge of computerized searching. DoE converted a non-thesaurus subject index to an authority file, but continued to maintain the index on a stand-alone DataEase application for use by cataloguers. Neither library converted acquisitions data
