Hi Katrin and Caroline, below is closely related to bug 35115 but still applies
here.
There are 2 scenarios that I'm seeing:
1) the eholding title was imported from a list of biblios (biblio existed
before the eholding title, may have a lot of MARC info)
2) the eholding title is created and added to a package, this prompts a biblio
to be created from the eholding title info, the only MARC the biblio has at
this point comes from the data in the eholding title, not a lot of MARC info)

The current problem is that when a eholding title is saved, it'll update the
MARC of its currently linked biblio (currently is doing this badly, overwriting
the linked biblio's MARC), regardless if the biblio originated from a list or
if it was created from the eholding title.

Possible solution:
1) have all the MARC mappings in place to create the biblio when the eholding
is manually created with as much MARC data as possible
2) dont do any changes to the biblio when eholdings title are created from a
"import from biblio list"
3) dont do any changes to the biblio when eholdings title is updated (this
means that post edits to the eholdings title are not reflected to the linked
biblio)

Another possible solution would be to prevent the edit of a eholding title if
it has a linked biblio, and update the eholding title only when the biblio is
updated from the MARC framework UI, but this also has issues because not all
fields have mapping (see bug 32782), i.e. some eholding title fields would not
be editable this way.
