Q. How do I find articles that are not available through a database?

If you can't access an article that you need you have 2 options:

Option 1: Check if there is a legal, freely available copy.  The LibKey Nomad browser extension flags up open access journal articles, as well as articles we subscribe to, when you’re browsing the web. You will also see a link to click through and check access options in StarPlus.

Alternatively you could check Open Access sites directly

Option 2: Request the article through the InterLibrary Request service. We may be able to get a digital copy of the article for you from the British Library.
There are a few ways to place an interlibrary request:

Via Find It @ Sheffield - When you click on the Find It @ Sheffield link in a database, and we don't have a subscription to the article, StarPlus will open in a new window displaying Interlibrary request options.
