Sharing References With Zotero Groups
Zotero's "Groups" feature allows you to share references with other Zotero users online. This is a great way to work collaboratively on research projects.
To join an existing Zotero group library:
Personal and group libraries are entirely separate, and changes made to items in one library do not affect the other. You can drag items back and forth across libraries to copy items.
NOTE: Create a new shared group from the Create a New Group page of the Zotero website. Groups may be public (searchable, and anyone can join) or private (users can only join if invited).
