A stub is an article that is too short to provide encyclopedic coverage of the subject, but not so short as to provide no useful information. To qualify as a stub it must at least define the meaning of the article's title. Often that means three to ten short sentences, but less text may be sufficient to qualify as a stub for articles on narrow topics, and complicated topics with more than ten sentences may still be stubs. However, in reality, many articles which are labeled as stubs are much longer than that. You can help MapleWiki by removing inappropriate stub notices.
Another way to define a stub is an article so incomplete that an editor who knows little or nothing about the topic could improve its content after a superficial Web search or a few minutes in a reference library. An article that can be improved by only a rather knowledgeable editor, or after significant research, may not be a stub.
Sizeable articles which lack wikification or copy editing are generally not considered stubs, and the normal procedure is for one of the cleanup tags to be added to them instead. Note that small articles with little information may end up being nominated for deletion or be merged into another relevant article.
