To find duplicates,click on “Duplicate Items” under 'My Library.' This will display the items Zotero thinks are duplicates in the center pane. You will be prompted to choose the version of the item to use as the master and then you can click "Merge."

Zotero currently uses the title, DOI, and ISBN fields to determine duplicates.

Go to for detailed instructions.
