    Abstract
    We illustrate the principle of unified treatment of all authority data for any kind of entities, subjects/topics, places, events, persons, organizations, etc. through the design and implementation of an enriched authority database for organizations, maintained as an integral part of an authority database that also includes subject authority control / classification data, using the same structures for data and common modules for processing and display of data. Organization-related data are stored in information systems of many companies. We specifically examine the case of the World Bank Group (WBG) according to organization role: suppliers, partners, customers, competitors, authors, publishers, or subjects of documents, loan recipients, suppliers for WBG-funded projects and subunits of the organization itself. A central organization authority where each organization is identified by a URI, represented by several names and linked to other organizations through hierarchical and other relationships serves to link data from these disparate information systems. Designing the conceptual structure of a unified authority database requires integrating SKOS, the W3C Organization Ontology and other schemes into one comprehensive ontology. To populate the authority database with organizations, we import data from external sources (e.g., DBpedia and Library of Congress authorities) and internal sources (e.g., the lists of organizations from multiple WBG information systems).

    Abstract
    The paper introduces TinREAD (The Information Navigator for Readers), an integrated library system produced by IME Romania. The main feature of interest is the way TinREAD can handle a classification-based thesaurus in which verbal index terms are mapped to classification notations. It supports subject authority control interlinking the authority files (subject headings and UDC system). Authority files are used for indexing consistency. Although it is said that intellectual indexing is, unlike automated indexing, both subjective and inconsistent, TinREAD is using intellectual indexing as input (the UDC notations assigned to documents) for the automated indexing resulting from the implementation of a thesaurus structure based on UDC. Each UDC notation is represented by a UNIMARC subject heading record as authority data. One classification notation can be used to search simultaneously into more than one corresponding thesaurus. This way natural language terms are used in indexing and, at the same time, the link with the corresponding classification notation is kept. Additionally, the system can also manage multilingual data for the authority files. This, together with other characteristics of TinREAD are largely discussed and illustrated in the paper. Problems encountered and possible solutions to tackle them are shown.

    Abstract
    The German subject headings authority file - SWD - provides a terminologically controlled vocabulary, covering all fields of knowledge. The subject headings are determined by the German Rules for the Subject Catalogue. The authority file is produced and updated daily by participating libraries from around Germany, Austria and Switzerland. Over the last twenty years, it grew to an online-accessible database with about 550.000 headings. They are linked to other thesauri, also to French and English equivalents and with notations of the Dewey Decimal Classification. Thus, it allows multilingual access and searching in dispersed, heterogeneously indexed catalogues. The vocabulary is not only used for cataloguing library materials, but also web-resources and objects in archives and museums.

    Abstract
    The paper presents experiences and challenges encountered during the planning and creation of the Universal Decimal Classification (UDC) authority database in the National and University Library in Zagreb, Croatia. The project started in 2014 with the objective of facilitating classification data management, improving the indexing consistency at the institutional level and the machine readability of data for eventual sharing and re-use in the Web environment. The paper discusses the advantages and disadvantages of UDC, which is an analytico-synthetic classification scheme tending towards a more faceted structure, in regard to various aspects of authority control. This discussion represents the referential framework for the project. It determines the choice of elements to be included in the authority file, e.g. distinguishing between syntagmatic and paradigmatic combinations of subjects. It also determines the future lines of development, e.g. interlinking with the subject headings authority file in order to provide searching by verbal expressions.

    Abstract
    From the very beginnings of library automation, subject authority control has been considered an important bibliographic tool in the Czech National Library (CNL). Effective subject access cannot exist without standardised access points. Subject authorities are considered an indispensable reference tool in supporting the selection of subject access points and normalizing content indexing. Most importantly, they are heavily relied upon when it comes to customisation of links between bibliographic records and subject access points in order to create a user-friendly subject browsing and searching environment. Because of the fact that the Universal Decimal Classification (UDC) is widely used in Czech Libraries it has become a readily available language independent subject framework which can be complemented by a more user-friendly subject heading system. In this context, the subject authority control offers a means of enhancing subject headings' access points with terminology and the semantic links available in UDC. Furthermore classification is used to enrich relationships between authority records themselves. The author will discuss in more detail the different aspects and advantages of subject authorities in which a classification and a subject heading system complement one another and the way this is implemented in the CNL.

    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
    Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve search by increasing the number of access points, they are rarely an integral part of the information retrieval process, particularly end-users searches. A retrieval prototype, searchFAST, was developed to test the feasibility of using an authority file as an index to bibliographic records. searchFAST uses FAST (Faceted Application of Subject Terminology) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST methodology complements, rather than replaces, existing WorldCat.org access. The bibliographic file is searched indirectly; first the authority file is searched to identify appropriate subject headings, then the headings are used to retrieve the matching bibliographic records. The prototype demonstrates the effectiveness and practicality of using an authority file as an index. Searching the authority file leverages authority control work by increasing the number of access points while supporting a simple interface designed for end-users.

    Abstract
    This article presents a conceptual framework for library name authority control, including methods for disambiguating agents that share the same name and for collocating works of agents who use multiple names. It then discusses the identifier solutions tried or proposed in the library community for name authority control, analyzes the various identity management systems emerging outside of the library community, and envisions future trends in name authority control.

    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
    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 article shares a vision of the enterprise of cataloging and the role of catalogers and metadata librarians in the twenty-first century. The revolutionary opportunities now presented by Semantic Web technologies liberate catalogers from their historically analog-based static world, re-conceptualize it, and transform it into a world of high dimensionality and fluidity. By presenting illustrative examples of innovative metadata creation and manipulation, such as non-MARC name authority records, we seek to contribute to the libraries' mission with innovative projects that enable discovery, development, communication, learning, and creativity, and hold promise to exceed users' expectations.

    Abstract
    This article describes the project to build the initial International Standard Name Identifier (ISNI) database by deploying the techniques used to develop the Virtual International Authority File (VIAF). It focuses particularly on the work of the OCLC team in transforming the VIAF "resource file" model of matched data into a robust, operational, and authoritative file of uniquely assigned ISNIs as a base for an ongoing ISNI assignment system, and on the quality assurance validation of the database provided by the British Library and the Bibliothèque nationale de France. The need for future interaction between ongoing ISNI assignment and name authority control in libraries is also explored.

    Abstract
    Die Gemeinsame Normdatei (GND) ist seit April 2012 die Datei, die die im deutschsprachigen Bibliothekswesen verwendeten Normdaten enthält. Folglich muss auf Basis dieser Daten eine Repräsentation für die Darstellung als Linked Data im Semantic Web etabliert werden. Neben der eigentlichen Bereitstellung von GND-Daten im Semantic Web sollen die Daten mit bereits als Linked Data vorhandenen Datenbeständen (DBpedia, VIAF etc.) verknüpft und nach Möglichkeit kompatibel sein, wodurch die GND einem internationalen und spartenübergreifenden Publikum zugänglich gemacht wird. Dieses Dokument dient vor allem zur Beschreibung, wie die GND-Linked-Data-Repräsentation entstand und dem Weg zur Spezifikation einer eignen Ontologie. Hierfür werden nach einer kurzen Einführung in die GND die Grundprinzipien und wichtigsten Standards für die Veröffentlichung von Linked Data im Semantic Web vorgestellt, um darauf aufbauend existierende Vokabulare und Ontologien des Bibliothekswesens betrachten zu können. Anschließend folgt ein Exkurs in das generelle Vorgehen für die Bereitstellung von Linked Data, wobei die so oft zitierte Open World Assumption kritisch hinterfragt und damit verbundene Probleme insbesondere in Hinsicht Interoperabilität und Nachnutzbarkeit aufgedeckt werden. Um Probleme der Interoperabilität zu vermeiden, wird den Empfehlungen der Library Linked Data Incubator Group [LLD11] gefolgt.

    Abstract
    Bibliographic data is used to describe resources held in the collections of libraries, archives and museums. That data is mostly available on the Web today and mostly as linked data. Also on the Web are the controlled vocabulary systems of name authority files, like the Virtual International Authority File (VIAF), classification systems, and subject terms. These systems offer their own linked data to potentially help users find the information they want - whether at their local library or anywhere in the world that is willing to make their resources available. We have found it beneficial to merge authority data for names on a global level, as the entities are relatively clear. That is not true for subject concepts and terminology that have categorisation systems developed according to varying principles and schemes and are in multiple languages. Rather than requiring everyone in the world to use the same categorisation/classification system in the same language, we know that the Web offers us the opportunity to add descriptors assigned around the world using multiple systems from multiple perspectives to identify our resources. Those descriptors add value to refine searches, help users worldwide and share globally what each library does locally.

    Abstract
    The paper provides an illustration of the benefits of subject authority control improving multilingual subject access in NEBIS - Netzwerk von Bibliotheken und Informationsstellen in der Schweiz. This example of good practice focuses on some important aspects of classification and indexing. NEBIS subject authorities comprise a classification scheme and multilingual subject descriptor system. A bibliographic system supported by subject authority control empowers libraries as it enables them to expand and adjust vocabulary and link subjects to suit their specific audience. Most importantly it allows the management of different subject vocabularies in numerous languages. In addition, such an enriched subject index creates re-usable and shareable source of subject statements that has value in the wider context of information exchange. The illustrations and supporting arguments are based on indexing practice, subject authority control and use of classification in ETH-Bibliothek, which is the largest library within the NEBIS network.

    Abstract
    To investigate which authority data elements are recorded by libraries in the Chinese character cultural sphere (e.g., Japan, Mainland China, Hong Kong, Taiwan, South Korea, and Vietnam), data elements recorded by each library were examined and compared to authority data elements defined in the standard Resource Description and Access (RDA) design. Recommendations were then made to libraries within this cultural sphere to improve and internationally standardize their authority data. In addition, suggestions are provided to modify RDA in an effort to increase compatibility with authority data in the Chinese character cultural sphere.

    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
    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.
