When you wish to change a single subfield in an authority then use Authority Change or the Cataloguing module. However, when you wish to make a change across subfields in more than one authority then use Global Change.

In the following topics you’ll see how you can use Global Change to insert a new subfield in multiple authorities. You'll also see how to delete the variant forms of an authority, and attach the works that were attached to the variant forms to the authorised form.

We’ll also work through an example showing how the same change could be made using Edit Heading and Global Change.
