Set Preferences
Before you import any search results in EndNote, we suggest you to preset your preferences to maximize the Find Duplicates feature in EndNote. Follow the steps below:
- Go to Edit, then click Preferences.
(For Mac: Click on EndNote X9 next to the Apple icon on the top-right corner, then select Preferences.
In Endnote 21, a short cut 
to the Preference setting is easily located at the end of the display bar)
- Select "Duplicates". Uncheck "Author" and "Reference Type". Find duplicates based on Year and Title only will help you find more records that are likely duplicates.
- Select "Display Fields". Reorder your display fields to show Record Number, Author, Year, Pages, Title and Name of Database. These fields help you quickly scan for additional duplicates.
