I do think it is related to this being a f/g heading.

Date: Tue, 9 Oct 2012 17:16:26 -0400 From: Nancy Kandoian <[log in to unmask]> To: [log in to unmask] Greetings -- Can someone please tell me, has there been some recent change in subject headings such that it is deemed more appropriate to use this topical heading for Sanborn fire insurance maps: Fire risk assessment $z [State] $z [City] $v Maps rather than this heading: Fire insurance $z [State] $z [City] $v Maps ? It recently came to our attention that some records in OCLC have been changed to reflect this. Perhaps the change is related to the introduction of the use of the genre/form heading "Fire insurance maps" on Sanborn maps? The few records with this change that I looked at were most recently replaced about a year ago. A little embarrassed that it took me so long to notice -- Nancy Kandoian NYPL Map Div.
