If you have imported references on the same subject from more than one online resource, you may find that you have some duplicate references in your library. It is important to remove duplicates if you intend to use EndNote with Word to cite references, to avoid errors in your bibliography.
EndNote will search the currently selected references for duplicates. To search the whole EndNote Library, click on the All References folder
- Go to the References menu and select Find Duplicates.
- Compare duplicate references to decide which to keep. The display automatically highlights any differences it has detected between the references, if any. You can copy and paste information between references if necessary.
- If you select Keep this record the other record will be sent to Trash.
- If you want to keep both records, or decide later, click on Skip to go to the next duplicate.
- If you decide to Skip or Cancel, References are held in a temporary Duplicate References group. This group is discarded when you close your library. Duplicate reference are highlighted. To delete all the automatically detected duplicates, click on one of the highlighted references, hold down the left mouse button and drag across to the Trash folder. All of the highlighted references will be transferred to the Trash folder.
- Make sure to organise your centre pane where your references are displayed so that you can see all the useful fields clearly to help you judge whether a reference is a true duplicate. It can also be useful to set your output style to Annotated so that the reference preview includes the abstract.
- To catch any outstanding duplicates it can be helpful to manually look through your library after sorting your references by the Title field. A second check where references are organised by Page number is helpful as a final check.
