Wikipedia is a valuable encyclopedia just as much as other news articles or websites with reliable and trustworthy sources. It is published everyday by common people, but it is a credible source with many appropriate topics including news, pictures, school information and education resources. Wikipedia has extended and gone out in many directions, not just an encyclopedia, but a vast website with millions of historic pages, with many appropriate topics.
Wikipedia is valuable because it is an online source of information that is updated by the Internet users. As with most Internet information, there is credibility that is questionable but that stipulation is valid with most online information. Wikipedia is valuable because it saves the user from using paper sources.
