Moving Sources to a New Collection
Removing Sources from a Collection
Deleting a Source
Eliminating Duplicates
For instruction on adding sources to your Zotero Library, consult the Adding Sources section of this guide.
With the Find Duplicates, Zotero compares sources based on these fields: Author, Year, Title, and Reference Type. Differences within records may omit duplicate items. You can check your library for duplicates at any time.
Instead of merging duplicates, you can also delete specific sources as needed.
