It is possible to, in some cases, link directly to full-text.
While every database or resource is different many will include a "friendly" URL or permalink button that will allow you to copy a URL that can be shared with other users.
These permalinks will sometimes include the link in your browser search bar; however, please note that this link is not always shareable and may not work for other users. Be sure to test these links in another browser or incognito window before saving or sharing.
