Abstract

Controlled vocabularies are a foundational concept in library science and provide a framework for consistency in cataloging practices. Subject headings provide valuable access points to library resources during search and discovery for patrons. Many librarians will be familiar with the more widely used controlled vocabularies, like those maintained by national libraries or major professional organizations. More recently, there has been an increasing shift toward specialized vocabularies maintained by independent entities intended for much narrower use. While there is valid criticism of the nature or content of controlled vocabularies, they will likely continue to be an important feature in information organization.

摘要

受控词汇表是图书馆学中的基础概念，为编目实践中的一致性提供了框架。在顾客搜索和发现期间，主题标题为图书馆资源提供了宝贵的访问点。许多图书馆员会熟悉更广泛使用的受控词汇，例如由国家图书馆或主要专业组织维护的词汇。近来，由独立实体维护的专门词汇已经越来越多地打算用于更狭窄的用途。尽管对受控词汇的性质或内容存在有效的批评，但它们可能仍将继续成为信息组织中的重要特征。
