From Wikipedia, the free encyclopedia
Wikipedia has index system called Categories, in which links to articles are provided based on category tags included in each article.
To add an article to a particular category, add [[Category:Category name]] to the article's text (preferably at the bottom). The assigned category should now show up at the bottom of the article, and a link to the page should show up on the indicated category page in Wikipedia's category system.
