Authorities in Koha
Koha has a number of ways of managing Authority Records. Here are a few options.
How Can I Identify Unused Authorities?
If you'd like to do some authorities clean-up and want to start with identifying authorities with no bibliographic records attached to them, there's a plugin for that: the Unused Authorities Report plugin.
Once it is installed under Administration > Manage plugins, you can run the plugin.
You will have options for whether to output the results to your screen or a .csv file, and you can search specific authority types. Displaying results to the screen will provide a direct link back to the authority record, though the csv output will provide enough information to search for the records via the Authorities module if you want to make an initial sweep and come back to investigate later. The plugin recommends searching no more than 5000 records at a time, so it may be quite an undertaking for a large consortium with a lot of authorities. However, it is a good housekeeping starting point, especially before utilizing a third-party service for authority clean-up.
Automatically Link Authority Records
Libraries can link authorities while cataloging. A button in the Basic Editor will link the authorities in the record with existing authorities in the database.
To use this feature, the library will need to set the system preference, AutoCreateAuthorities, to "don't generate". The ability to automatically link authorities using a button is currently only available in the Basic Editor and not in the Advanced Editor.
Once the linking has occurred, Koha will create an informational box to indicate which authorities linked to existing authorities and which did not. This information box makes it easy to know what authorities need to be created.
Within the authority record, Koha will highlight the authorities with a green color, meaning it found a match, or a red color, meaning no match was found.
No other interaction needs to happen - the user can then save the record.
Adding a See Also to an Authority Record
Here is a short tutorial on adding a 'See Also' to an authority record.
See Also
Koha gives libraries the ability to modify their authority records to include 'See Also' links. These 'See Also' links can be new authority records, existing authority records, or authority records added via z39.50.
To add a 'See Also' to an authority record, you will search for your authority record in the Authorities module. Once you have found the authority record, click on the Actions button and choose Edit. This will bring you into the full authority record. The 5 tab is where the 'See Also' options live.
An example of what an authority record looks like with 'See Also' included can be seen in this screenshot:
Adding MARC fields to authority search
The system preference, AdditionalFieldsInZ3950AuthSearch, gives libraries the ability to add more fields to the z39.50 authority search. This is similar to the system preference, AdditionalFieldsInZ3950ResultSearch, which allows libraries to add more MARC fields in the bibliographic search using z39.50.
Within this system preference, libraries can add a MARC field and subfield to display when a search is performed and the results of that search will include this additional field.
Authority Notes
In the authority search, 6xx Notes are clickable and a pop-up window will display all the notes found in the authority record.

- From the results, there is a Note link that once clicked will reveal the 6xx notes.
Preview of Authority Record in MARC View
Koha has a link from within the authority record to show a MARC preview.
Customizable Authority Fields
In Koha 22.05, two new system preferences are introduced to allow libraries to customize the values in fields found in the authority record.
- GenerateAuthorityField667
- GenerateAuthorityField670
Previously, when Koha created a machine-generated authority record, default text was included in the fields 667 and 670. Now, Koha will allow libraries to edit this text to fit the library's workflow.
Each of these system preferences has a text box with the default text included, which can be added to or edited.
