What term describes standardized terms used to describe the content of library materials, aiding organized searching?

• A. Keywords
• B. Subject headings
• C. Descriptors
• D. Tags

Answer: (B)

Describing library materials with standardized terms to support organized searching relies on a controlled vocabulary that assigns a specific, consistent label to each item’s topic. This is what subject headings do in catalog records: they are standardized terms chosen from authorities (like the Library of Congress Subject Headings) to represent what a work is about. Because these terms are shared across catalogs and indexers, a search for a topic retrieves all relevant materials, even if different items use different words in their descriptions. The standardized nature and the hierarchical and cross-referencing features of subject headings help users find exactly what they need without missing related topics. A few related ideas help clarify why this choice is best. Keywords are useful for discovery but are free-text and vary from item to item, so they don’t provide the same consistency or recall across the catalog. Tags are user-generated labels and can be highly inconsistent and informal, which undermines systematic searching. Descriptors might be used in indexing, but the established, widely adopted term for describing content in library catalogs is subject headings.
