## 6.4 Duplicate references

If you import references from multiple databases into EndNote, you may find that you have some duplicate references in your library. You can detect these duplicate references in EndNote and deduplicate them.

1. Click on Library.
2. Select 'Find duplicates'
3. EndNote now shows the duplicate references and displays a pop-up window for the duplicates.
4. In the pop-up window, you can select the reference you want to keep by clicking 'Keep this record' above the reference. If you want to keep both references, click 'Skip' at the top right.
5. When there are no more duplicate references, the pop-up window will close.
