Pre-coordinate indexing creates subject headings by combining multiple concepts before indexing. Which option best describes this approach?

• A. Using only one concept per heading
• B. Combining after retrieval
• C. Combining concepts before indexing
• D. Ignoring relationships between formats

Answer: (C)

Pre-coordinate indexing creates a subject heading by fusing multiple concepts into one heading before indexing. This means the heading itself encodes the exact combination of ideas that describe the item’s subject, so a search using that composite heading retrieves the item directly and precisely. This approach is advantageous because it preserves the relationship among concepts in a single, standardized term, making retrieval more exact and consistent across the catalog. If you tried to represent the subject with just one concept, you’d risk missing important aspects of the item. If you combined concepts after retrieval, you’d be applying relationships at search time rather than having them embedded in the heading, which is less precise. The idea of ignoring relationships between formats isn’t about indexing and doesn’t describe how headings are formed. A practical sense of it is to think of a work that covers multiple related ideas—like a heading that explicitly links multiple concepts such as information storage and retrieval and digital libraries within one composite term. That single heading communicates the full subject and supports precise discovery.
