Zotero lets you share references using a feature called "Groups." Groups are a good way to share references with a class, work closely with research collaborators, and keep track of conversations happening in your field.
First, set up Zotero sync and synchronize your library.
You now have two sections in your Zotero collections pan: My Library and Group Libraries.
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 between libraries to copy items.
Groups may be public (searchable and anyone can join) or private (users can only join if invited).Refer to the full Zotero documentation for details on permissions and adding members to a Group.
