International Standard Authority Data Number
The International Standard Authority Data Number (ISADN) was a registry proposed by the International Federation of Library Associations and Institutions (IFLA) to provide and maintain unique identifiers for entities described in authority data. Having such a unique number would have the benefits of being language-independent and system-independent. Francoise Bourdon was a major proponent of such a standard, proposing a structure for the ISADN and recommending that the number uniquely identify authority records, rather than their subjects. A 1989 article by Delsey described the work on the IFLA Working Group on an International Authority System, spending a good portion of time on conceptualizing an international standard number "that will facilitate the linkage of variant authorities for the same identity." Their discussion was very complex in its discussion of which agencies would actually assign such numbers. For example, a national library might be tasked with assigning iden ...

International Federation Of Library Associations And Institutions
The International Federation of Library Associations and Institutions (IFLA) is the leading international body representing the interests of people who rely on libraries and information professionals. An independent, non-governmental, not-for-profit organization, IFLA was founded in Scotland in 1927 and maintains headquarters at the National Library of the Netherlands in The Hague. IFLA sponsors the annual IFLA World Library and Information Congress, promoting universal and equitable access to information, ideas, and works of imagination for social, educational, cultural, democratic, and economic empowerment. IFLA also produces several publications, including IFLA Journal. IFLA closely partners with UNESCO, resulting in several jointly produced manifestos. IFLA is also a founding member of Blue Shield, which works to protect the world's cultural heritage when threatened by wars and natural disaster. History IFLA was founded in Edinburgh, Scotland, on 30 September 1927, when li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unique Identifiers
A unique identifier (UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. The concept was formalized early in the development of computer science and information systems. In general, it was associated with an atomic data type. In relational databases, certain attributes of an entity that serve as unique identifiers are called primary keys. In mathematics, set theory uses the concept of '' element indices'' as unique identifiers. Classification There are some main types of unique identifiers, each corresponding to a different generation strategy: # serial numbers, assigned incrementally or sequentially, by a central authority or accepted reference. # random numbers, selected from a number space much larger than the maximum (or expected) number of objects to be identified. Although not really unique, some identifiers of this type may be appropriate for identifying objects in many practical applications ...

Authority Control
In information science, authority control is a process that organizes information, for example in library catalogs, by using a single, distinct spelling of a name (heading) or a numeric identifier for each topic. The word ''authority'' in ''authority control'' derives from the idea that the names of people, places, things, and concepts are ''authorized,'' i.e., they are established in one particular form. Note: root words for both ''author'' and ''authority'' are words such as ''auctor'' or ''autor'' and ''autorite'' from the 13th century. These one-of-a-kind headings or identifiers are applied consistently throughout catalogs which make use of the respective authority file, and are applied for other methods of organizing data such as linkages and cross references. Each controlled entry is described in an authority ''record'' in terms of its scope and usage, and this organization helps the library staff maintain the catalog and make it user-friendly for researchers. Catalogers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbara Tillett
Barbara Ann Barnett Tillett (born 1946) is a librarian and library scholar known for her work on authority control and bibliographic data modeling. Library of Congress Tillett began working at the Library of Congress in 1994. As director of the Library's Integrated Library System (ILS) Program from August 1997 through July 2001, Tillett undertook the massive task of leading the selection and implementation of the Library of Congress' first Integrated Library System. A library press release referred to the project as the "largest single information technology project in the Library's history." Tillett served as chief of the Library's Cataloging Policy & Support Office, which sometimes put her into conflict with Sanford Berman's subject heading activism. Tillett retired from the Library of Congress on November 30, 2012. Cataloging theory Tillett has been particularly well known for her development and explanation of the FRBR model. Tillett served as a consultant to the IFLA St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual International Authority File
The Virtual International Authority File (VIAF) is an international authority file. It is a joint project of several national libraries and operated by the OCLC, Online Computer Library Center (OCLC). History Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities. This would present all the benefits of a common file without requiring a large investment of time and expense in the process. The VIAF concept was introduced at the 2003 World Library and Information Congress, hosted by the International Federation of Library Associations and Institutions, International Federation of Library Associations. The project was initiated by the US Library of Congress (LC), the German National Library (DNB) and the OCLC on 6 August 2003. The Bibliothèque nationale de France (BnF) joined the project on 5 October 2007. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Cataloging And Classification
A library is a collection of materials, books or media that are accessible for use and not just for display purposes. A library provides physical (hard copies) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVD, CD and cassette as well as access to information, music or other content held on bibliographic databases. A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government; an institution such as a school or museum; a corporation; or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources.
