There are a few ways to search for articles, both academic and non academic.
In your search results you will find a lot of the articles will be attached as a PDF or HTML file with the article citation. See result #12.
If however there isn't a PDF or HTML file like #13 then you will need to click Where can I get this? Often when you click this you'll be led to an Open Access version of the article or directly to the publisher's website where you can read it. Sometimes though there is no online access to the article and you will need to request the article be sent to the ECU library via interlibrary loan. You will be able to request an interlibrary loan when you click Where can I get this? and there is no further online access to an article or there is not a print version of the article in the library.
