LCSH
The Library of Congress Subject Headings (LCSH) comprise a thesaurus (in the information science sense, a controlled vocabulary) of subject headings, maintained by the United States Library of Congress, for use in bibliographic records. LC Subject Headings are an integral part of bibliographic control, which is the function by which libraries collect, organize, and disseminate documents. It was first published in 1898, a year after the publication of Library of Congress Classification (1897). The last print edition was published in 2016. Access to the continuously revised vocabulary is now available via subscription and free services. Subject headings are normally applied to every item within a library's collection and facilitate a user's access to items in the catalog that pertain to similar subject matter, in order to save time finding items of related subject matter. Only searching for items by 'title' or other descriptive fields, such as 'author' or 'publisher', would take more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanford Berman

Bibliographic Control
In library and information science, cataloging ( US) or cataloguing ( UK) is the process of creating metadata representing information resources, such as books, sound recordings, moving images, etc. Cataloging provides information such as author's names, titles, and subject terms that describe resources, typically through the creation of bibliographic records. The records serve as surrogates for the stored information resources. Since the 1970s these metadata are in machine-readable form and are indexed by information retrieval tools, such as bibliographic databases or search engines. While typically the cataloging process results in the production of library catalogs, it also produces other types of discovery tools for documents and collections. Bibliographic control provides the philosophical basis of cataloging, defining the rules that sufficiently describes information resources, to enable users find and select the most appropriate resource. A cataloger is an individual re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Of Congress Classification
The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress in the United States, which can be used for shelving books in a library. LCC is mainly used by large research and academic libraries, while most public libraries and small academic libraries used the Dewey Decimal Classification system. The classification was developed by James Hanson (chief of the Catalog Department), with assistance from Charles Martel, in 1897, while they were working at the Library of Congress. It was designed specifically for the purposes and collection of the Library of Congress to replace the fixed location system developed by Thomas Jefferson. LCC has been criticized for lacking a sound theoretical basis; many of the classification decisions were driven by the practical needs of that library rather than epistemological considerations. Although it divides subjects into broad categories, it is essentially enumerative in nature. That is, it p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subject Heading
In information retrieval, an index term (also known as subject term, subject heading, descriptor, or keyword) is a term that captures the essence of the topic of a document. Index terms make up a controlled vocabulary for use in bibliographic records. They are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. They are used as keywords to retrieve documents in an information system, for instance, a catalog or a search engine. A popular form of keywords on the web are tags, which are directly visible and can be assigned by non-experts. Index terms can consist of a word, phrase, or alphanumerical term. They are created by analyzing the document either manually with subject indexing or automatically with automatic indexing or more sophisticated methods of keyword extraction. Index terms can either come from a controlled vocabulary or be freely assigned. Keywords are stored in a search index. Common words li ...

Illegal Aliens (Library Of Congress Subject Heading)
Illegal aliens is a topical subject term in the Library of Congress Subject Headings thesaurus, that is, a phrase assigned by librarians to describe the content of books and other documents in a library catalog. The subject heading became a topic of political interest in the United States in 2016, when a decision by the Library of Congress to revise the heading and replace it with the terms "''unauthorized immigration''" and "''noncitizens''" was opposed by congressional Republicans. Background The subject heading "''Aliens, Illegal''" was established by the Library of Congress in 1980 and revised to "''Illegal aliens''" in 1993. The subject heading incorporates references from non-preferred forms of the term including "''Aliens--Legal status, laws, etc.''"; "''Aliens, Illegal''"; "''Illegal aliens--Legal status, laws, etc.''"; "''Illegal immigrants''"; "''Illegal immigration''"; and "''Undocumented aliens''". It also references related terms such as "''Alien detention centers'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SKOS
Simple Knowledge Organization System (SKOS) is a W3C recommendation designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary. SKOS is part of the Semantic Web family of standards built upon RDF and RDFS, and its main objective is to enable easy publication and use of such vocabularies as linked data. History DESIRE II project (1997–2000) The most direct ancestor to SKOS was the RDF Thesaurus work undertaken in the second phase of the EU DESIRE project . Motivated by the need to improve the user interface and usability of multi-service browsing and searching, a basic RDF vocabulary for Thesauri was produced. As noted later in the SWAD-Europe workplan, the DESIRE work was adopted and further developed in the SOSIG and LIMBER projects. A version of the DESIRE/SOSIG implementation was described in W3C's QL'98 workshop, motivating early work on RDF rule and query languages: A ...

Thesaurus (information Retrieval)
In the context of information retrieval, a thesaurus (plural: "thesauri") is a form of controlled vocabulary that seeks to dictate semantic manifestations of metadata in the indexing of content objects. A thesaurus serves to minimise semantic ambiguity by ensuring uniformity and consistency in the storage and retrieval of the manifestations of content objects. ANSI/NISO Z39.19-2005 defines a content object as "any item that is to be described for inclusion in an information retrieval system, website, or other source of information". The thesaurus aids the assignment of preferred terms to convey semantic metadata associated with the content object. A thesaurus serves to guide both an indexer and a searcher in selecting the same preferred term or combination of preferred terms to represent a given subject. ISO 25964, the international standard for information retrieval thesauri, defines a thesaurus as a “controlled and structured vocabulary in which concepts are represented by terms ...

Center For Inquiry
The Center for Inquiry (CFI) is a US nonprofit organization that works to mitigate belief in pseudoscience and the paranormal, as well as to fight the influence of religion in government. History The Center for Inquiry was established in 1991 by atheist philosopher and author Paul Kurtz. It brought together two organizations: the Committee for the Scientific Investigation of Claims of the Paranormal (founded by Kurtz in 1976) and the Council for Secular Humanism (founded by Kurtz in 1980). In January 2016, CFI announced that it was merging with the Richard Dawkins Foundation for Reason and Science. In June 2009, Kurtz left CFI over a conflict with then-CEO Ronald A. Lindsay. Committee for Skeptical Inquiry Through the Committee for Skeptical Inquiry (CSI), and its journal, ''Skeptical Inquirer'' magazine, published by the Center for Inquiry, CSI examines evidential claims of the paranormal or supernormal, including psychics, ghosts, telepathy, clairvoyance, UFOs, and ...

Tim Spalding
LibraryThing is a social cataloging web application for storing and sharing book catalogs and various types of book metadata. It is used by authors, individuals, libraries, and publishers. Based in Portland, Maine, LibraryThing was developed by Tim Spalding and went live on August 29, 2005, on a freemium subscriber business model, because "it was important to have customers, not an 'audience' we sell to advertisers." They focused instead on making a series of products for academic libraries. Motivated by the cataloguing opportunities and financial challenges presented by the COVID-19 pandemic, the service went "free to all" on March 8, 2020, while maintaining a promise to never use advertising on registered users. As of February 2021, it has 2,600,000 users and over 155 million books catalogued, drawing data from Amazon and from thousands of libraries that use the Z39.50 cataloguing protocol. Features The primary feature of LibraryThing (LT) is the cataloging of books, mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyperlink
In computing, a hyperlink, or simply a link, is a digital reference to data that the user can follow or be guided by clicking or tapping. A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is known as anchor text. A software system that is used for viewing and creating hypertext is a ''hypertext system'', and to create a hyperlink is ''to hyperlink'' (or simply ''to link''). A user following hyperlinks is said to ''navigate'' or ''browse'' the hypertext. The document containing a hyperlink is known as its source document. For example, in an online reference work such as Wikipedia or Google, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanisms such as tables of contents, footnotes, bibliographies, indexes, letters, and glossaries. In some hypertext, hyperlinks can be bidirectional: they can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
