subject heading scheme


Web NDL Authorities is a service by the National Diet Library (NDL), Japan, to access authority data created and maintained by the NDL. Name headings or Subject headings are assigned to the bibliographic data to distinguish different people with the same name or to identify people who use pseudonyms, nonstandard spellings, transliterated names, or other variants. To control these headings, authority data is organized to indicate alternative headings, synonyms, and the basis of choice for the headings.

OLAC Video Game Vocabulary

"Video games are extremely popular materials held by both public libraries and academic libraries. There is a compelling need for a robust genre vocabulary for cataloging video games that will aid users in identifying video game titles by genre. (...) The OLAC video game genre vocabulary includes sixty-six genre terms, each with a scope note to help librarians choose the correct term when cataloging video games. The vocabulary is fully cross-referenced and includes authoritative sources to corroborate the usage of the genre term as applied to video games.

IPTC NewsCodes

The International Press Telecommunication Council (IPTC) creates and maintains sets of concepts – called a controlled vocabulary or a taxonomy – to be assigned as metadata values to news objects like text, photographs, graphics, audio and video files and streams. This allows for a consistent coding of news metadata across news providers and over the course of time.

Wessex Annotated Subject Heading Index

"This annotated index to the Wessex Classification Scheme was produced primarily for cataloguers within the SWIMS Network (formerly SWRLIN) Cataloguing Co-operative. The Classification Scheme has been adopted by other library networks in the UK and is widely used. Each indexing term in the annotated index refers to a suggested classification number or numbers within the Wessex Scheme. The index, however, should never be used as a classification tool on its own.
