Paul, Have you been able to isolate instances when the old version of the 1xx was added as a new 4xx? I haven't been able to isolate this type of record in our normal weekly bib processing (I haven't looked real hard, though). When we get our first authority notification run later this month, I'll be looking for this type of record. In Sirsi's Unicorn, when a 1xx changes Unicorn adds a temporary 4xx that contains the old form of the 1xx. This is used to support automatic updating to the new form. III, however, has no similar feature. If there is no 4xx with the old form, the heading will not be changed to the new form. Unfortunately, with death dates being added to personal name headings and records being transferred from the subject file to the name file (or vice versa), many records with changed 1xx fields do not contain a 4xx with the previous form.

Hi Bob
Thanks for the reply.
I do wait to the next day, yes, and in fact I've tried all sorts of permutations like overlaying one day, suppressing the next, unsuppressing the next, then looking at the bibs that day after that, but there's never a change.
What I generally do in fact is to overlay a batch, then eyeball the HTML reports sent by Backstage at the same time as the files. Most of the changes don't affect the 1XX -- 95 percent of them are changes like adding new 4XX or 670, quite a lot in fact are just cases where the authorized heading used to end with a full stop (sorry, period) and now DLC have revised it by taking out the full stop. So most of those things are not going to impinge on bib headings at all. But if the 1XX itself has been amended in a significant way, I do a manual global update (if you see what I mean) to the bib records because I know AACP is not going to do the change for me.
Cheers
