The phrase 'motion pictures' as a subject heading illustrates which library practice?

• A. Subject indexing
• B. Author indexing
• C. Title indexing
• D. Publisher indexing

Answer: (A)

Topic-based access through a subject heading is demonstrated when a resource is tagged with a descriptive topic. Using "motion pictures" as a subject heading shows we’re describing the item's content by its subject, which is the essence of subject indexing. This lets users find the item when searching by topic, regardless of who created it, what the title is, or who published it. In contrast, author indexing would attach the creator’s name, title indexing would use the work’s exact title, and publisher indexing would label items by who published them.
