Save certain subfields from being overwritten via F3 and PTC
When linking names, subjects etc. from authority files in various BIB fields, some cataloguing conventions require giving additional information in certain cases.
One example for such a requirement, stemming from the German speaking countries, is to add the time and place of an auction when linking to the genre/form term “auction catalogs” in BIB field 655 (see attached screenshot). This additional information is, of course, specific for each BIB record and must not be overwritten or deleted, if at a later point in time either PTC processes said BIB record or a colleague invokes the F3 functionality.
Since different subfields might be used for various types of additional information, based on the field number and the cataloguing tradition and/or authority file linked to, it would be sensible to allow to define specific subfields to be exempt based on the field number, but also the authority file in use ($2).

Just adding my voice to all previous comments stressing this is particulary problematic in relation to field 830 with $v being overwritten

Field 830 $v should not be overwritten to prevent errors

Field 830 $v very useful

We would be happy, if especially in field 830 the subfield $v would not be overwritten. That causes correction time and even errors the way it is actually.

Especially in field 830, it would be a great help if the subfield $v were not overwritten.

Another example for such a requirement is $v in field 830_0. The volume number is specific for each BIB record and it would avoid correction time or even errors if the subfield was not overwritten by copying field 830 with F3.

Protects data from accidental manipulation and enables higher quality. This eliminates time-consuming troubleshooting and correction work.

What does "PTC" mean?
