In a duplex-numeric system, how are records filed?

• A. Filed consecutively by first number then second number, etc.
• B. Filed by alphabetical order
• C. Filed only by second number
• D. Filed by date of filing

Answer: (A)

In a duplex-numeric filing system, records are organized by a multi-part number where the first part takes precedence and sets the broad group, and any subsequent parts refine the order within that group. You first consider the primary number, grouping all records with that number together, then sort within that group by the second number, and so on if more parts exist. This creates a stable, hierarchical order that makes retrieval efficient and scalable. For example, all records starting with 101- come before those starting with 102-, and within 101-, 101-01 comes before 101-02, which comes before 101-10, and so on. This differs from alphabetical filing, which would sort by names or titles; or from filing only by the second number, which would ignore the main grouping; or filing by date, which orders by when records were created rather than by their numeric code.
