Narrow that topic down! This is the part of the process we call "pre-search": scratching the surface of a large topic to uncover keywords, subtopics, and more. It's much easier to write a paper on a narrowed topic, trust us. Use the tools and suggestions below to dig into a large topic (ex: mental illness, homelessness, PTSD, and so forth) so that it is manageable.
It's perfectly okay to look at a Wikipedia page to learn more about your topic when you're doing presearch, but you would not want to use this as a formal resource for your paper. What you can do is use Wikipedia's links and references to locate more authoritative and credible sources. In many cases you can find more authoritative resources, such as books and published articles from these references.
