If you find duplicate publication records, you can merge them using the work space rather than deleting a record.
Follow these steps below.
Click the check box next to each record, then check the green work space icon for each record.
This will move the duplicates to the Work space so that you can merge them.
In the top header bar, you will find the Work space icon with the number of records available to merge.
Then select the duplicate records, then click "Join" the records. This will merge the records.
Go to My publications and click on the title of the publication you just merged to open.
Then open the data sources tab to view all records for this publication.
Click the star next to the record you want to display in your profile.
