You can allow teachers and staff to post a title from Destiny to their Twitter or Facebook.
To make the change in their Access Level go to Back Office>Access Level. Choose the patron group and click on the edit icon next to that group. Open the the Patron sub tab and check the box "Able to post to social media sites"
These icons will be visible in the title details.
FYI - this option does not work in the Elementary interface of the catalog, regardless of Quest or Classic options.
