== MARC21 Rules ==
You catalogue serials (magazines, journals, etc) and also some select articles contained within them. You wish for borrowers to be able to navigate from the serial record down to the article records within, and back again. 
To achieve this, the following MARC21 rules have been outlined by the LOC.
Parent Record	Child Record

=== For Parents Record (Serial) ===
You must define the record type in the Leader as follows:
==== LDR - Leader ====
For a 'Serial Issue', the Bibliographic level bit (position 7) should be set as follows for Parent to Child links to display;
* s = 'Serial'
==== 001 - Control Number ====
When combined with Control Number Identifier must be unique.
==== 003 - Control Number Identifier ====
Used to identify the institution the record was catalogued in. In a union catalogue, this is used in combination with Control Number to make a unique identifier for the record.
==== 774 - Constituent Unit Entry ====
It is no longer recommended to create these as it can lead to unmanageably large MARC records for the parent serials.
=== For Child Records (Articles) ===
You must define the record type in the Leader and you must define a 773 field as described below for linked to work:
Note: If UseControlNumber is enabled and EasyAnalytics is disabled, then these records can be added from the parent New menu using New child record
==== LDR - Leader ====
For an 'Analytic record', the Bibliographic level bit (position 7) should be set as follows for Parent to Child links to display;
* a = 'Monographic component part'
* b = 'Serial component part'
==== 773 - Host Item Entry ====
For Child to Parent links to work as expected, the first indicator must be set to literal `0` and the `w` subfield must contain the control number of the parent record.
Optionally, you can also fill out the `t` and `g` subfields.
== Koha Practical Requirements ==

With UseControlNumber set to Use koha will use the host serial records 001 - Control Number to link article records back to their container serials. 
Koha does NOT yet support the combined Control Number + Control Number Identifier to build links, and thus the 003 does not have to be populated, and the child 773_w subfield should contain ONLY the parent Control Number and not the combination
Koha will IGNORE any 774's set in the parent record, and so you should follow the guidance above and not populate them. Koha will however build a search based upon the parent control number to find linked articles from the parent to the children.
All other rules should be followed as described by the LOC above.
