On the screen with detailed information about the article, check to see if there are links to the full text on the left-hand side of the page (PDF or HTML). If the article is only available in PDF format, you will need to click the PDF Full Text link to open it. The HTML format of full text is located below the article citation and abstract so scroll down.
Some articles are not available in full-text. This means that you will only find their summary. If you need an article that the library doesn't own, you can request it through Ask a Librarian.
