The National Academy of Sciences has a terrific webpage of evolution resources that addresses many issues surrounding evolution, ranging from basic understanding of what it is, all the way to addressing the current controversy between evolution and creationism.
It probably won't change the minds of people who cannot accept science for what it is, but it certainly is a good resource for many who are trying to figure out what all the brouhaha is all about. There really is no good excuse anymore to be ignorant about this matter. This resource is giving you everything you might need to know about evolution, and all of them are at your fingertips. Anyone who still makes the annoying argument that it is "only a theory" should be smacked on the back of the head already.
