The argumentative essay, also known as a "pro/con" paper, is a basic rhetorical form of writing that many students find difficult to do successfully. One challenge of the argumentative essay is that its success depends on your providing valid evidence to support the argument. Research is particularly important.
This research guide makes finding valid evidence a little easier -- the library resources that will work well for this assignment are listed here in this guide.
This guide also gives you important information on citing and the MLA citation style, criteria for critiquing the resources you use, as well as information on how to do library searches.
