Unlisted WHO CAN ACCESS? Only those with access to the document or hub URL. This is safer than sending PDF via email since the author can always update content, monitor the URL ad, if needed, change/revoke/expire access. WHEN TO USE If your content is intended for a limited audience. Unlisted documents/hubs allow frictionless access to the content. You will need to share the document/hub URL with people.
