Zotero users can create collaborative or interest . Shared group libraries make it possible to collaboratively manage research sources and materials, both online and through the Zotero client. Zotero.org can be the hub of all your project group's research, communication and organization. This video from RMTBC Library provides a step by step in creating groups in Zotero
There are two ways to create Zotero groups:
If you have enabled data syncing and are a member of a group with an enabled library, the group library will appear in Zotero for Firefox or Zotero Standalone in the left column. Items can be dragged into it from My Library and viewed or edited by other group members, if their permissions allow it. To create a subcollection, right-click on a group library and select New Subcollection. Note that group libraries are wholly separate from My Library. Any items dragged into them are separate copies and changes to the items will not be reflected in your own copy of the item until you drag it back into My Library. This example shows a group library for a group project in APSC200 and the group owner can add other members to create a space to manage the resources found by every group member
Every group also has its own web page. For public groups, this page acts as a public portal for the group’s collaborative work. For private groups, the page offers a way for group members to interact with the group’s collections from anywhere.
