If you do searches limiting to .org sites, Wikipedia will invariably be the first result you get. We all know that Wikipedia in and of itself is neither "scholarly" or "peer-reviewed" - but you still might be able to use it in your *RESEARCH PROCESS* but not as a source itself:
(1) get some background and familiarize yourself with a topic, and also
(2) find the sources they cited - all (or at least most) Wikipedia articles end with References and/or Further Readings sections that point you to additional sources. These sometimes include peer-reviewed journal articles, government sources, and/or community sources that you can find in the library or online.
