<font size="+1">Hello Marc<br>
<br>
I am not sure whether this will be relevant, but tag 001 may not be the
same for two MARC records describing the same book if they came from
different sources. If you are re-loading the same data this should not
be a problem, but if you are loading new records it might mean you get
duplicates as the 001 fields might not match. Here is the relevant
entry from the Library of Congress.

<br>
</font>001- Contains the control number assigned by the organization
creating, using, or distributing the record. For interchange purposes,
documentation of the structure of the control number and input
conventions should be provided to exchange partners by the organization
initiating the interchange. The MARC code identifying whose system
control number is present in field 001 is contained in field 003
(Control Number Identifier). An organization receiving a record <b>may
move the incoming control number</b> from field 001 (and the control
number identifier from field 003) to field 035 (System Control Number),
010 (Library of Congress Control Number), or 016 (National
Bibliographic Agency Control Number), as appropriate, <b>and place its
own system control number in field 001</b> (and its control number
identifier in field 003). <br>

<pre wrap="">Dear all,
I cannot figure out, how to set up a working matching rule for tag 001
Control Number or tag 999$d Biblioitem Number.
Please find my rules below - any suggestions how to correct the rules
would be appreciated.
Trying on Koha 3.01.00.032,
Best regards,
Marc
