Periods in manual numbers are used when a manual is volumized due to its size.

• A. The manual is volumized due to size
• B. The manual has multiple authors
• C. The manual is decommissioned
• D. The manual is classified

Answer: (A)

Periods in manual numbering indicate the document has been split into volumes because it is too large to fit in a single manual. When a manual is volumed, each sub-volume gets its own number with a period to show it’s part of a larger set. This numbering helps you navigate to the right section across multiple volumes and keeps a clear, consistent reference system. The other scenarios—having multiple authors, being decommissioned, or being classified—don’t inherently require or explain this period in the numbering, so they don’t account for why the periods appear.
