This is a list of basic subjects for which Wikipedia should have a corresponding high-quality article, and ideally a featured article. It also serves as a centralized watchlist and tracks the status of some of Wikipedia's most essential articles. Articles that are Featured articles are marked with a star (); articles that are considered Good articles are marked with a green circle (); articles that have cleanup tags on them or are stubs, and thus need to be improved as soon as possible, are marked in bold.
