When you find an article you like that only has a Full text available link, click that link or the title of the article to go to the next screen.
On the next screen, click the name of the database that has the full text. In this example, it's JSTOR Arts and Sciences V.
When there is more than one database link, always compare the year of the article you want (underlined in red) to the years available in the databases (also underlined in red). In this example, you need 2010. The first database begins coverage in 1880, the second one in 1997, so 2010 is available from either one of them.
When you find an article you like that has multiple links, you can bypass STEP 2 by clicking either Get PDF or Read Online.
The Read Online link will take you to the HTML version of the article. The exact same article appears in both the PDF and HTML versions. The difference is a matter of preference--the PDF usually has a better font and better graphics.
