Occasionally while searching for articles within a database you will find a resource that the library does not have access to. In a case like this you can request the article directly through the database.
When searching in PubMed or another database you'll see a blue HSCLink button. Click there to see if the library has access. If we do you'll be taken to the full text of the item.
If the library doesn't own the item you'll be taken to a More Options page.
