Journal, magazine and news articles, videos and audio on controversial topics in the news. The best way to use this is to find "topics", read the introductory article, and browse the selected articles under the topic. Featured articles have commentary which place the articles in context. I made it easy for you and linked out to all the sports related topics :)
Use these when you want to find the link between your topic and the world of business, science, psychology, etc.
Tip: you don't need to read the whole article. Scan the title and read the abstract. That will usually give you enough information to use in your paper.
If you find a good article with no PDF, ask your librarian to get it for you. Allow a few days for the article to arrive. The librarians will be requesting it from a service offered by the Boston Public Library.
A good place to start your research. Articles are 1-10 pages long and place your topic in context, explains history, and introduces you to important names, organizations and ideas.
