To remove duplicate references in Endnote:
1. In the Groups panel in the left column, click on a particular group, or click on "All References" to display all the references in your library.
2. From the menu bar, select References > Find Duplicates
3. If you have duplicate references in your library, the Find Duplicates dialog box will appear. For each set of duplicates, you have the following options:
- Click Keep This Record to save the preferred reference and discard the other in the trash.
- Click Skip to leave both references in the library. The references will be placed in a temporary Duplicate References group for later review.
- Click Cancel to see the entire list of potential duplicate articles at once.
