Zotero's Groups feature allows you to share references with other Zotero users online. It's a great way to work on collaborative research projects.

First, set up Zotero sync and synchronize your library.
- To create a shared library, click the Create Groups button near the top left of your Zotero window (small blue/green button with two “people” icons, second from the left).
- To join an existing Zotero library, search for it at zotero.org/groups or be invited by the group’s owner.
- You must log in to the zotero.org website to create or join a group.
You now have two sections in your Zotero collections pane: My Library and Group Libraries.
- Personal and group libraries are entirely separate.
- Changes made to items in one library do not affect the other.
- You can drag items back and forth to libraries to copy items.
Search for existing public groups or create a new group. Groups may be public (searchable, and anyone can join) or private (users can only join if invited).
