Authority records are a way of controlling fields in your MARC records. Using authority records will provide you with control over subject headings, personal names and places.
To add a new authority record, choose the authority type from the 'New Authority' button.
The form that appears will allow you to enter all of the necessary details regarding your authority record.
To expand collapsed values simply click on the title and the subfields will appear. To duplicate a field or subfield just click the plus sign (+) to the right of the label. To use field helper plugins simply click the ellipsis (...) to the right of the field.
When linking authorities to other headings, you can use the authority finder plugin by clicking the ellipsis (...) to the right of the field.
From there you can search your authority file for the authority to link. If you can't find the authority to link, you can click the 'Create new' button and add the necessary authority for the link. This plugin also allows for you to choose the link relationship between the authorities.
From the authorities page you can search for existing terms and the bibliographic records they are attached to.
From the results you will see the authority record, how many bibliographic records it is attached to, and a delete link (if there are no bibliographic records attached).
Clicking on the Details link to the right of the authority record summary will open the full record and the option to edit the record.
If the authority has See Alsos in it you will see those broken out on the search results, clicking the linked headings will run a search for that heading instead.
Authorities can be edited by clicking on the authority summary from the search results and then clicking the 'Edit' button above the record.
Once you've made the necessary edits, simply click 'Save' and if you have the dontmerge system preference set to 'Do' the next time the merge_authorities.pl cronjob runs it will update all of the bib records that use that authority.
To delete an authority record you first must make sure it's not linked to any bibliographic records. If it is not used by any bibliographic records a 'Delete' link will appear to the right of the record on the search results and as a button that appears after clicking on the summary of the authority record.
