To share Zotero libraries with a group:
Using the groups in Zotero requires the free Zotero account on www.zotero.org. After creating the account, use the menu in the Zotero cloud account and click on “Groups.” You can then “Create a New Group.”
Choose a name for your group. We suggest making the membership private, so that only people you invite can work with your shared library.
If you want everyone to be able to contribute citations to the Shared Library, make sure you select the option Library Editing: Any group members.
When you are looking at Zotero Groups, click the link "Manage Members."
You can send invitations by clicking the link "Send More Invitations."
Then enter their email addresses by separating each with a comma.
Each user you invite will receive an email named "Zotero Group Invitation," with a Zotero link to accept or decline the invitation.
In this same area ("Members Settings") you can update roles of members, giving them different permissions for managing the group's library.
After creating a group, you can then create a shared folder and add citations to the shared folder.
If you go to the Zotero software on your computer, you will now see an area under your Zotero library called "Group Libraries."
TIP: If you don't see the group library in your Zotero software, click the "sync" icon to force an update!
Each group will have its own folder. Within that group folder will be folders for citation, just like standard Zotero.
When you wish to add citations to this new folder, simply highlight it so citations will be added to it as you search in databases. Or you may drag and drop from an existing Zotero folder into this group folder.
You will need to sync for the items gathered into standard Zotero to appear in the cloud account of Zotero, including the groups area.
