Library Sciences QUESTION #1510
Question 1
The principle of 'literary warrant' in subject heading construction means that:
  • Headings are assigned only to fiction works
  • New subject headings are created only when actual documents on a topic exist in the literature✔️
  • Headings must be in the language of the cataloguer
  • All headings must be approved by the Library of Congress
Correct Answer Explanation
Literary warrant is the principle that a subject heading or classification number should only be established when there is actual published literature on the topic to justify it. It grounds controlled vocabulary in existing documented knowledge.
