Below I've included links to other library databases for you to explore if you want.Have fun and ask me if you need help while you're doing research for this assignment!
Why not just search with Google?
You can certainly find news on Google. You also find lots of other stuff, like blog posts, websites, reports and so on. Using the databases will help you focus just on news articles.
What is the difference between a news article and an opinion piece or editorial?
News articles published by reputable newspapers are written by journalists and rely on sources to inform the reader about a newsworthy event from a more or less neutral perspective.
Opinion pieces or editorials (also called op-eds) may also rely on sources; however, the purpose is not to inform but to persuade. The writer of an editorial is clearly taking a side or recommending a course of action and is constructing an argument to persuade others to their point of view.
What's the most reliable approach I can take to find the right kind of article for my assignment?
Your instructors have recommended several publications as good sources for this assignment. If you can find an article from one of these sources, and you make sure that it is a news article and not an opinion piece, then you should be able to feel confident in the article you have chosen.
