The article should be left in those categories it would belong to if it had no category of its own; see [[Wikipedia:Categorization and subcategories#Topic article rule]] as well as [[Wikipedia:Categorization#Some general guidelines]].

~~==Why might a category list not be up to date?==~~

Sometimes, pages are not placed in categories manually by Wikipedia editors, but by means of [[WP:Template|template]]s, which can be used to place identical information (including category membership information) on many different pages at once. When the information on such a template is edited, the pages containing that template are updated, but not necessarily updated immediately. This means that pages might not always appear in the most current categories. However, this problem usually affects project maintenance categories rather than the categories used for browsing.

Various other temporary delays may sometimes mean that lists of category members or subcategories, or the page counts given, are not completely up to date. So if you are editing Wikipedia and find that your page hasn't yet shown up in a category or been removed from an old category, don't panic! The problem may resolve itself within minutes, but sometimes it may take longer, in some cases days, even weeks. (It may help if you make a [[Help:null edit|null edit]] to the page.)
