Can I check for duplicate references in EndNote 21?

Answer

If you have imported a large number of references, you may have duplicates. These can be removed using the de-duplication tool in EndNote 21.

  1. Open the group you would like to check, or select ‘All references’ to check your full library.
  2. Select ‘Library’ from the menu, and click ‘Find Duplicates’.
  3. You will then be able to compare references to decide which to keep. When you choose to keep a reference, the other will be sent to ‘Trash’.
  4. You can also choose to ‘Skip’ or ‘Cancel’, which will place your references in a temporary ‘Duplicate References’ group (which will be deleted when you close the EndNote application).
