New heading *
*
When a new heading is being created that would use an existing “AACR2 compatible” *
heading in its 1XX field, establish the new heading using a reformulated AACR2 heading; upgrade *
the heading on the name authority record coded “AACR2 compatible” and upgrade any additional *
name authority records that have used the reformulated “AACR2 compatible” heading. *
