You want this paper https://www.acpjournals.org/doi/10.7326/M19-1941 ... but ... you run into a paywall - US$35 to buy it.
Click on a bookmarklet and the link becomes this https://login.smhslibresources.health.wa.gov.au/login?url=https://www.acpjournals.org/doi/10.7326/M19-1941 and the publisher site recognises you as authorised EMHS / SMHS staff member and gives you the full text and the pdf. The bookmarklet has added the Library's proxy prefix to the link that is needed for a publisher site to allow access.
This will work for most journals, however, occasionally the authentication is more complex and you will need to go through the Library's Journals A to Z catalogue to gain access.
For instance - Library access to the Lancet is not from the Lancet site but from Science Direct - applying the bookmarklet against the Lancet site will not link you to full text - you need to be in the Science Direct interface.
