If a series is added, deleted, or changed in a later iteration:
Change the series area to reflect the current iteration.

LCRI 21.30L: Integrating Resource in One or More Series
LC practice: Also provide an 8XX series added entry for any traced series included in a note. (Series not present on the latest iteration will be given in the note area instead of in the series area — cf. AACR2 12.6B2 and 12.7B14.2b.)
