[Koha] OCLC enhanced content & 856 tag

[Cab Vinton]

Thanks, Galen.

That does seem to be the trick. I tried deleting the $x, $3 subfields
for a number of other records & that also worked fine.

It's interesting, however, that not all records actually have a string
input for the "key". The 856's for cover art, for example, don't
require it ...

Thanks again,
