Wikipedia Wikipedia is 'the free encyclopedia that anyone can edit'. Wikipedia contains pages for most towns and vilages in Britain, and our web site tries to link you to them, but you must decide for yourself whether you can rely on the information you find there. Many of the 'village' pages contain only 'stub articles', which you can add to. We suggest that pages which give sources for particular statements are more reliable than pages which simply have a long reference list at the end, or no references to sources at all.
