Setup User Permissions

From your libraries dashboard, click on the gear icon on the left hand side of the screen.

After clicking on the gear icon, find and click on permissions.

Once you are in the permissions area, use the dropdown menu to pick which user group you would like to edit permissions for.  You will be shown a list of features and accessibility for each user type/group that you can enable/disable access to.  

Once you are finished, be sure to hit the save button after you have made your changes.
