In this topic we'll see an example of changing the tag number for an authority.

In this example, the subject heading “Swedish language materials” has been mistakenly catalogued as a geographic term in a 651 field rather than a topical term in a 650 field. This has therefore created a 151 authority rather than a 150.

 

To change the tag number:

1. Click the Heading hyperlink to display the MARC record, and then click Edit Heading to display the Authority Change page.
2. Select “150 - Topical Term” from the Tag drop-down list.

3. Before you update the database you can click Test Update to see what the effects of the change will be.
4. Click Update Record to make the change.
