Online encyclopedia Wikipedia consists of millions of articles in more than 270 languages. The name comes from the Hawaiian word wiki meaning 'quick', which has gradually been adopted to denote a kind of technology that enables collaborative websites and ‘encyclopedias’.


The articles on Wikipedia are written by tens of thousands of volunteer contributors all over the world. In addition, hundreds of thousands of registered visitors make daily edits to the content. As a result, Wikipedia is a massive online source of information on an enormous range of subjects.


Those contributing as writers and editors can do so regardless of their qualifications, so quality can vary and some 'editing' is carried out for not altogether positive reasons. All users are advised to consult other sources to verify Wikipedia's content before quoting it in a factual publication, as its 'open source' approach leaves it vulnerable to inaccuracies.
