12.3G. Successive designations
Rule 12.3G should be applied only after the cataloger has decided that "a serial (record)" not "serials (records)" is to be created based on the following guidelines:
Two Records:
Create separate records when a serial’s enumeration repeats the exact numeric designation and the publisher does not link the old and new systems with a designation such as "new series" or "second series."
One Record:
Create a single record with appropriate notes when any of the following changes occur in the numeric and/or chronological designations:
1. The numeric designation begins again with number "1" but has a different designating term.
2. A serial begins with a chronological designation and changes to a numeric designation, beginning with "1," or the reverse - begins with numeric and changes to chronological. (Note: there is at any time only one uniquely identifying designation system.)
3. A serial begins again with the number "1" and the publisher links the old and new systems with the term "new series" or similar wording.
4. A serial begins with only a chronological designation and then changes to a numeric designation that accounts for the previously published chronological issues.
Changes in Designation Systems:
Do not consider a serial to have adopted a new designation system if it begins by having both a numeric and a chronological designation and drops one of the designations, or, if a serial begins with either a chronological or numeric designation and the other designation (numeric or chronological) is added later. Explain such changes in notes (see 12.7B8 ).
