Since the serial record represents the entire run of the serial, and the series numbering is likely to change with each issue, normally omit series numbering (AACR2 12.6B1). The numbering may be given when all or part of the number remains constant with every issue, or when the serial consists of only one issue or a limited span of issues with consecutive numbers (LCRI 12.6B1). Note that when given, numbering is recorded in the series statement in the form in which it appears on the piece and it is recorded in the tracing in the form in which it appears in the authority record (field 642; e.g., use of "no." etc.).
