You are mistaken. Both the old AAP and the new AAP are for an Expression, not the Work. The AAP for the Work is Lonergan, Bernard J. F. $t Works, which does not currently have an authority record.
I am curious about a “Works” name-title authority record.
The NACO authority with heading
Lonergan, Bernard J. F. $t Works. $f 1988
was recently changed to
Lonergan, Bernard J. F. $t Works (Lonergan Research Institute)
I don’t believe this is legitimate RDA usage, is it?
My understanding is that there is only one “Works” work for each author, possibly with multiple expressions. The parenthetical qualifier here is at the work level, and thus distinguishes this “work” from other “works” that constitute the complete works of Lonergan. (Getting through these multiple senses of “work” is a lot of work.) That does not seem to be correct.
