Canadian Subject Headings
Canadian Subject Headings (CSH) is a list of subject headings in the English language, using controlled vocabulary, to access and express the topic content of documents on Canada and Canadian topics. Library and Archives Canada publishes and maintains CSH on the Web. Prior to the merger of the National Library of Canada and the National Archives of Canada, the National Library of Canada published a print version of CSH. Université Laval also publishes Répertoire_de_vedettes-matière_de_l'Université_Laval, Répertoire de vedettes-matière (RVM), a list intended to provide access to Canadian subject headings in the French language.

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 ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Répertoire De Vedettes-matière De L'Université Laval
The Répertoire de vedettes-matière de l'Université Laval (RVM) is a controlled vocabulary made up of four mostly bilingual thesauruses. It is designed for document indexers, organizations that want to describe the content of their documents or of their products and services, as well as anyone who wants to clarify vocabulary in English and French as part of their work or research. RVM was created and is updated by the Répertoire de vedettes-matière section of the Université Laval Library in Québec City, and it contains over 300,000 authority records. It is used by over 200 public and private libraries and documentation centres in Québec, across Canada and some other countries, mostly in Europe.

Faceted Application Of Subject Terminology
Faceted Application of Subject Terminology (FAST) is a general use controlled vocabulary based on the Library of Congress Subject Headings (LCSH). FAST is developed as a part of WorldCat by OCLC, Inc., with the goal of making subject cataloging less costly and easier to implement in online contexts. FAST headings separate topical data from non-topical data, such as information about a document's form, chronological coverage, or geographical coverage. Unlike LCSH headings, which are pre-coordinated (multiple terms are linked together by the cataloger in a specific order, e.g. "United States -- History"), FAST headings are post-coordinated (terms are singly assigned, so the user can mix and match, e.g. "United States" and "History"). Use OCLC has been developing FAST since 1998, and originally intended the system to describe Web resources in simple metadata schemata, particularly Dublin Core. FAST separates headings into eight distinct facets: topical, geographic, personal name, corp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Of Congress Subject Headings
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] |
Subject Headings Authority File
The or SWD (translated as ''Subject Headings Authority File'') is a controlled vocabulary index term system used primarily for subject indexing in library catalogs. The SWD is managed by the German National Library (DNB) in cooperation with various library networks. The inclusion of keywords in the SWD is defined by (RSWK) (English: Rules for the keyword catalogue). Similar authority systems in other languages include the Library of Congress Subject Headings (LCSH) and the (). Since April 2012 the SWD is part of the (GND) (English: Integrated Authority File). Scope The SWD has about 600,000 descriptors and 700,000 non-descriptors (synonyms and quasi-synonyms) as well as synonymous descriptor chains with references to a descriptor. Its growth rate is about 5.5% per year. About three-quarters of the descriptors refer to individual concepts (language identifier, person, entity, title, ethnography etc.) and a quarter are abstract concepts.

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.
