Wikipedia
Wikipedia is a free collaborative encyclopedia. As anyone can edit any article, it is possible for biased, out of date, or incorrect information to be posted on it. However, because there are so many other people reading the articles and monitoring contributions, incorrect information tends to be corrected quickly. Some articles contain references. Wikipedia may provide a useful starting point for learning about a particular topic, but for the purposes of academic study, information from it should be used in conjuction with standard peer-reviewed sources.
