Wikipedia has hundreds of departments staffed by a small army of volunteers. Here are some of the most general; for more specific departments, check the appropriate page below. See also the Wikipedia department directory.
Wikipedia has many established policies, guidelines, conventions, and traditions. This is a very brief sampling of some of the most important; for more information, see the main policies and guidelines page. Policies and guidelines apply both to articles and how to work with fellow editors. For easy access, the shortcuts to the pages are also listed.
