The BPS pays for student access to several databases. One useful database you can use is the Thomson Gale Database. This database gives you access to hundreds of thousands of articles from magazines, reputable journals, newspapers, and other sources. If you are at school, then just click on the previous link and go there and look around. There are six different databases you can search. Read the description and select the database or search all of them at once.
Make sure you record the citation information if you use one of the articles, as you are required to have a MLA works cited page and parenthetical citations.
