Finding information is not the end of research. You want information that supports the point you’re trying to make. Some sources can be outdated, biased, or just plain wrong, and using that information makes it a lot more difficult for you to present a convincing argument.
Even articles from the library's databases may not be a good choice if they do not support your argument.
Taking the time to critically evaluate information as you find it will help you to avoid wrong turns in the research process.
