There are a couple of ways to try and get through to the full text of an article you find in a CINAHL search.
1) Link to the PDF, if the PDF link is available:
2) Click on the 'Article Linker' button, or link, when there's no PDF link available:
If there is no PDF link, or the Article Link takes you to a page that says the journal isn't held, your next step would be to search the library's electronic journal list. There are instructions on how to do this in the eResources LibGuide
If you still have no luck, contact library staff for help. You can email us, or phone us, on (03) 364 0500.
