A stub is an article that provides at least a basic definition but does not go much beyond it. It may not be the perfect article yet, but each stub should have the potential to become one. See Wikipedia:Find or fix a stub for ways to locate stubs. For example, click what links here on that same page, or on Template:Stub (the stub notice).

Still not enough stubs? Then try Wikipedia:Requests for page expansion, or set the threshold for stub display in your user Preferences. That option sets a number of characters threshold value. Links to articles with fewer characters are shown in dark red. This makes it very easy to spot stubs. If the stub notice is a generic notice consider sorting the stub into a stub category.
