According to LCRI 12.0B1, the chief source for a series is a series title page or the chief source of the analytic when there is no series title page. If the series does not appear in either place, follow the order of preference given in the RI for assigning a title page substitute.

If the series consists of a main series and subseries, apply AACR2 12.1B4 and LCRI 1.6H and consider any source on which both appear together to be the chief source from which the series title is taken.
