Find and Remove Duplicates
As you add more and more references to your EndNote Library, from a variety of databases, it is likely that you will get duplicate records for the same item.
To avoid anomalies in your citations and references once you start adding them to your Word document, you need to ensure that you only have one record for each item.

You can also set which fields to match (the less fields selected the more possible duplicates it will find) by setting preferences. Note that the criteria used by EndNote to identify duplicate records won’t always catch all of them. You will still need to look through your Library and delete any records you don’t want. It is probably easiest to do this if you sort your Library by ‘Author’ or ‘Title’. Click on the column header to do this.
