[Koha] Zebra not updating biblios automatically in koha 3.8

[tajoli at cilea.it]

Hi to all,

>> the system control number (035 $a).  Are these kept unique by koha?

in fact, reading the bib marc21 standard, http://www.loc.gov/marc/bibliographic/bd001.html
I think to understand that the value in 001 must to be unique in your instance of Koha.
If you have an official LoC code of your library, with 001 + 003 you have a code unique at world level.

In fact the value of 003 is always the same for all bib records of your Koha instance.

The defintion of 001 in Unimarc is more clear "This field contains characters uniquely associated with the record, i.e. the control number for the record of the agency preparing the record.".
There is not equivalent of 003 in Unimarc.

In fact during input in Koha is possible to create a duplicate or a empty value in 001.
