How do I clean these up if I choose to?
- First identify which duplicate has less references by clicking on "Show records using this authority".
Make a slight change to the value in the authority you would like to remove.

- Select all the records that are returned and add them to a new label. This will allow you to find them in the next step.
- Go back to the authority you identified in step one and delete that authority.
- Exit the authority and open the label you created in step two. Select all the items in that label and do a group edit. Add the authority value back to the records and save.
