In several places under LC-PCC PS 6.27.1.9, the instructions direct us to use the AAP form of corporate body name when applying these as parenthetical qualifiers to Work access points.  One example gives “130  $a Occasional publication (Popular Archaeology (Firm)).”  Should the same approach be taken when qualifying Expressions in the same manner?  It makes sense to do so, though I’ve found no PS that explicitly states this.  Of course, the name in the 381 field would usually take the full AAP form.
