The typical access model to articles from PubMed is outlined below. It is important to note this will remain the default model.
LibKey eliminates the need to navigate to the Link Resolver (UK's InfoKat Discovery menu) and the publisher page - saving clicks and time. When LibKey locates an article PDF, it will automatically open it in a new tab once the "View Now UK" button is clicked.
Also note LibKey Link is limited to users routing through the UK version of PubMed, rather than the free NLM or PMC versions listed in the UK Databases list.
