Wikipedia:About

Wikipedia is a live collaboration differing from paper-based reference sources in important ways. Unlike printed encyclopedias, Wikipedia is continually created and updated, with articles on historic events appearing within minutes, rather than months or years. Older articles tend to be more comprehensive and balanced; newer articles may contain misinformation and/or unencyclopedic content. Any article may contain undetected vandalism. Awareness of this helps the reader to obtain valid information and avoid recently added misinformation (see Wikipedia:Researching with Wikipedia).
