When you think something needs clarity, feel free to look it up on a variety of sources before asking about whatever questions need to be answered. Wikipedia is a wiki, so anyone can edit almost any article by simply following the Edit this page link. You don't even need to log in. (Although there are some reasons why you might like to do so...)
The Wikipedia community encourages you to be bold. Don't worry too much about making honest mistakes—they're likely to be found and corrected quickly. If you're not sure how editing works, check out how to edit a page, or try out the sandbox to try out your editing skills. New contributors are always welcome.
Places to start researching include (but are not limited to):
- Any search engine, such as Google or Yahoo
- Google News for recent events
- Google Books or Archive.org which offers scanned copies of books
- Your local library; PublicLibraries.com lists public libraries by U.S. state; UK Public Libraries lists public libraries by the regions of the United Kingdom
- If you're just looking for answers to your questions, you can try the Wikipedia Reference Desk, although reliability is not guaranteed and answers given should not be used as resources for any academic paper or encyclopedia article.
