You can certainly try using the free Internet to find journal articles by searching Google, Bing or Yahoo - usually through an advanced search. However, most journal publishers expect payment to view the whole article.
Your library has subscription databases that house hundreds of thousands of journal articles. You have access to the entire journal article because your library pays for that acccess.
Using the library's subscription databases is the best, fastest and easiest way to find a journal article for your research.
Look at the type of document. Most databases will tell you this. You can either start your citation in NoodleTools by selecting 'database' and then choosing the type of media, OR you can select the type of media, and then choose 'database' from the tabs at the top of the next page.
You do not need to include a URL in NoodleTools as these direct links will not work outside of our subscription.
