A plugin that does one thing only: Detect and Manage duplicate items in .

Main Features

• Duplicates Detection
  • Detects if newly imported items are duplicates of existing ones in the Zotero library.
  • You can choose which version of duplicate items to use as the master item and merge them.
  • The actions you can take:
    1. Keep New: Set the new item as the master item and merge the duplicates.
    2. Keep Old: Set the existing item as the master item and merge the duplicates.
    3. Keep All: Keep both the new item and the existing item.
    4. Merge Manually: Go to the Duplicate Items Panel and merge the duplicate item manually.
• Auto-Bulk Merge
  • Merges all duplicate items in the library automatically.
  • Introduced in Version 2.0.0.
• Non-duplicates Management
  • Allows marking items as "Non-duplicates" if mistakenly identified as duplicates by Zotero.
  • Introduced in Version 3.0.0.
• Show Duplicate Statistics
  • Append the duplicate count on the label of Duplicate Items pane.
  • Introduced in Version 2.3.0.

If you find this project helpful, please consider giving it a star ⭐. It would be a great encouragement for me!

[!IMPORTANT]

Zoplicate does NOT delete the duplicate items arbitrarily.

Instead, it extracts the useful information from the duplicate items and merges them into the retained item.

It makes some improvements based on the official detection and merging methods of Zotero.
