Wikipedia is a free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation.
Wikipedia is the product of thousands of editors' contributions, each one bringing something different to the table, whether it be: researching skills, technical expertise, writing prowess, or tidbits of information, but most importantly a willingness to help. Wikipedia's entries had an overall accuracy rate of 80 percent, whereas the other encyclopedias had an accuracy rate of 95 to 96 percent.
