How to fully remove a field when cataloging
Koha frameworks shape MARC21 into workforms of information library staff can use to create records for their catalogue. The fields in these workforms can be edited in a variety of ways through the associated framework. This document will outline how to fully remove a field in a work form by using the ignore function.
It is important to note that removing a field from a workform using this method will mean information cannot be saved to the field. If a record is imported and has information in a field which is ignored in the framework it is being imported into, the information will be deleted.
For information about how to hide a field without fully removing it so information can still be saved in the hidden fields, or if you require more assistance with editing frameworks, please contact Interleaf Technology with a Changes to Framework form filled out.
Please note that the Default framework should never be edited.
Navigate to the MARC framework to be edited
Go to Koha administration > Catalog > MARC bibliographic framework
This will take you to a page with a table of the frameworks available on your site.
Custom frameworks can be created so the exact entries in this table can be different between different systems.
The framework with Default framework in the Description column and a blank field in the Code column is the Default framework. This Default framework should never be edited.
Edit the framework
Identify the framework from the table to be edited and click the Actions button to the right hand side of the line the framework is on. This will create a dropdown menu. Select MARC structure from this dropdown menu.
This will bring up a page with a table of the fields in the framework.
Across the top of the table there will be a search box, which can be used to limit the table to a specific field.
This example will use 245$b field, but the principles can be applied to whichever field you wish to edit. As the number being searched for is typed into the search box, the table of fields will narrow down to matching entries. Once the table has been reduced to the specific field to be edited, click the Actions button to the right hand side of the line the tag is on. This will create a dropdown menu. Select Edit subfields from this menu.
This will open a new page where the subfields that make up the tag appear. The subfields will be split into different tabs, based on the alphabetic and numeric representation.
Go to tab b, (or the tab of the subfield to be edited). This will show a form of information which controls the behaviour of the subfield.
Go to the Basic constraints section and go to the line Managed in tab.
Click the box to the right hand side and this will create a dropdown menu. Select Ignore from the dropdown menu.
Click Save changes at the bottom of the page.
The field will no longer appear on the workform.
