If you’ve ever had trouble trying to confirm a fact and don’t have a lot of time to hunt through the Internet, try looking at Wikipedia (www.wikipedia.org). It is an international, web-based, free-content, multi-language encyclopedia. Wikipedia material is written by volunteers and the content can be changed by anyone. The benefit is that you are reading information often written by an expert who is keen on the subject. The disadvantage is that not all the content is 100% accurate. However, Wikipedia can be a great quick reference for finding many facts or getting a general understanding of a topic.
