Pre-coordinate indexing is a method in which multiple concepts are combined by the indexer to form subject headings assigned to documents dealing with complex subjects. Which term describes this indexing method?

• A. Post-coordinate
• B. Pre-coordinate
• C. Faceted
• D. Retrospective

Answer: (B)

Pre-coordinate indexing is when the indexer creates a single, composite subject heading that encodes several concepts about the document. This means the heading itself already combines the different topics, so users can find the item by that one heading without needing to search for and fuse multiple terms separately. That’s why this option is the best fit for the description: the indexer is forming a unified heading that represents a complex subject. In contrast, post-coordinate indexing would involve attaching multiple separate terms to the record and letting the user or search system combine them during retrieval. Retrospective indexing refers to indexing materials after they’re in hand, not the method of creating the heading itself. Faceted indexing uses multiple independent facets to describe an item, which is related but describes a broader system of organizing terms rather than forming a single composite heading.
