John Marr is right.  We are being instructed to use a 700 field that *totally duplicates* the 100/240 or 100/245, when there are multiple expressions of the same work in the manifestation.  If we are told elsewhere that 100/24X constitutes the AAP when there's only one expression of the work (for the *vast* majority of the resources cataloged), why in the world doesn't it constitute the AAP for one of the expressions if another expression happens to be included?

This is not RDA confusion; RDA doesn't tell us to use 100 fields, it tells us to use an authorized access point for the work/expression (saying nothing about whatever specific container we're using for the data).  This is MARC confusion.  Or rather, this is PCC confusion/inconsistency about the function of MARC tags.

Proudly wearing the sensible shoes since 1978!
