When the DOI of an item already exists in Zotero

edited August 11, 2024
When I add an item from the web page whose DOI already exists in Zotero, can I add it again without creating a new item, but add the original item to the currently selected collection?
If there is no DOI number, it is better to add it directly and let the user handle it manually.
  • The Zoplicate plugin gives you those options. When it detects a likely duplicate it shows a simple interface where you can choose between all possible options:
    Keep New: Set the new item as the master item and merge the duplicates.
    Keep Old: Set the existing item as the master item and merge the duplicates.
    Keep All: Keep both the new item and the existing item.
    Merge Manually: Go to the Duplicate Items Panel and merge the duplicate item manually.
