Wikipedia is essentially an online encyclopedia that anyone (including you) can edit. Like any encyclopedia or other reference resources (i.e. dictionaries, atlases), they are not the "end all be all". Use them as a tool to help inspire your research.
Do watch out for any warnings at the bottom of the page. Because anyone can edit Wikipedia entries, the information may not be accurate, unbiased, contain citations, etc.
