Wikipedia offers great information about how Wikipedia should be used in terms of academic research on their Academic Use page:

As stated on the site, “any encyclopedia is a starting point for research, not an ending point”. Also, because Wikipedia can be edited by anyone, all information gathered from Wikipedia should be cross-referenced to ensure its accuracy. If the information you are gathering from Wikipedia is accurate and credible, you should be able to cite the source it originally appeared in, rather than Wikipedia itself.
