- 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
- 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
- This paper is the second in a series in D-Lib Magazine and describes a workflow management system being developed by the Digital Knowledge Center (DKC) at the Milton S. Eisenhower Library (MSEL) of The Johns Hopkins University. Based on experience from digitizing the Lester S. Levy Collection of Sheet Music, it was apparent that large-scale digitization efforts require a significant amount of human labor that is both time-consuming and costly. Consequently, this workflow management system aims to reduce the amount of human labor and time for large-scale digitization projects. The mission of this second phase of the project ("Levy II") can be summarized as follows: * Reduce costs for large collection ingestion by creating a suite of open-source processes, tools, and interfaces for workflow management * Increase access capabilities by providing a suite of research tools * Demonstrate utility of tools and processes with a subset of the online Levy Collection The cornerstones of the workflow management system include optical music recognition (OMR) software and an automated name authority control system (ANAC). The OMR software generates a logical representation of the score for sound generation, music searching, and musicological research. The ANAC disambiguates names, associating each name with an individual (e.g., the composer Septimus Winner also published under the pseudonyms Alice Hawthorne and Apsley Street, among others). Complementing the workflow tools, a suite of research tools focuses upon enhanced searching capabilities through the development and application of a fast, disk-based search engine for lyrics and music and the incorporation of an XML structure for metadata. The first paper (Choudhury et al. 2001) described the OMR software and musical components of Levy II. This paper focuses on the metadata and intellectual access components that include automated name authority control and the aforementioned search engine.

- Abstract
- Neither the standards nor the software underlying institutional repositories anticipated performing name authority control on widely disparate metadata from highly unreliable sources. Without it, though, both machines and humans are stymied in their efforts to access and aggregate information by author. Many organizations are awakening to the problems and possibilities of name authority control, but without better coordination, their efforts will only confuse matters further. Local heuristics-based name-disambiguation software may help those repository managers who can implement it. For the time being, however, most repository managers can only control their own name lists as best they can after deposit while they advocate for better systems and services.

- Abstract
- Normalization rules are essential for interoperability between bibliographic systems. In the process of working with Name Authority Cooperative Program (NACO) authority files to match records with Functional Requirements for Bibliographic Records (FRBR) and developing the Faceted Application of Subject Terminology (FAST) subject heading schema, the authors found inconsistencies in independently created NACO normalization implementations. Investigating these, the authors found ambiguities in the NACO standard that need resolution, and came to conclusions on how the procedure could be simplified with little impact on matching headings. To encourage others to test their software for compliance with the current rules, the authors have established a Web site that has test files and interactive services showing their current implementation.

- 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
- 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
- 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
- Um das Leben und Werk historischer Personen und historische Ereignisse verstehen zu können, benötigen Wissenschaftler als primäre Quelle historische Dokumente. Das Entdecken und Auffinden dieser Dokumente in Archiven ist seit jeher eine aufwändige Aufgabe. In vielen Fällen ist sie mit einer großen Portion Glück verbunden, die richtige Archivalie im Bestand ausfindig zu machen. Mit Katalogen und anderen Findmitteln helfen Archive Forschern bereits beim Aufspüren dieser Quellen. Um Material zu einer bestimmten Person auffindbar zu machen, werden in der Regel biographische Normdaten bereitgehalten, die als Einstiegspunkt in eine Suche dienen. Der Begriff "Normdaten" kann unter zwei Aspekten verstanden werden: 1. Vergabe und Verwendung einer eindeutigen Kennung für eine Person, um sie in verschiedenen Systemen zu finden und 2. als eine normierte Schreibweise, um biographische Daten zu einer Person so aufzuschreiben, dass die Daten interoperabel, also auch außerhalb des ursprünglichen Systems (nach-)genutzt werden können.

- 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.
