12.3B1. Numeric and/or alphabetic, chronological, or other designation Area. Numeric and/or alphabetic designation [Footnote] [New]
Premier Issues:
When the first issue bears wording implying "first," such as "premier issue," in addition to numbering, prefer to give the numbering because words such as these are not likely to continue as numeric designations on subsequent issues. If words such as "premier issue" have been recorded because there was no number or date on the first issue, supply numbering once it appears on subsequent issues according to 12.3D1.
Sources:
If all elements of the numeric designation do not appear on the same source, use judgment when deciding whether to piece then together or whether to omit part of the numbering. Take into consideration numbing found on later issues, when available. If in doubt, do not piece together.
Date Serves as Volume Number:
A date may serve as a volume number preceded or followed by internal numbering that repeats each year. Treat both as the numeric designation and record the number following the date.
