How to use Zotero to remove duplicates from literature?

Using Zotero's built-in functionality is the standard method to effectively identify and remove duplicate reference entries within your library. This process leverages metadata comparison and is feasible for libraries of various sizes. The automated detection relies on comparing bibliographic fields such as titles, authors, publication years, DOIs, and ISBNs. It is crucial to perform regular metadata retrieval beforehand to enhance matching accuracy. Users must carefully verify identified duplicates before merging, as automatic matching isn't infallible. The deduplication scope is limited to items within the same Zotero library; searching across group libraries concurrently requires checking each individually. Always confirm the final, merged record retains all necessary attachment links and notes. To implement, navigate to your library view. Access the deduplication tool via the `Library` menu and select `Find Duplicates`. Zotero will display potential duplicates grouped together for review. Manually inspect each group, select the entries you wish to merge into a single master record, and click `Merge X Items`. Repeat the process by clicking `Next Duplicate` until all groups are processed. This workflow significantly cleanses your library, improves data accuracy, and streamlines literature management, saving substantial research time.
