An article, as part of an [[encyclopedia]], tells the reader about a topic. It may cover an entire topic - and thus be comprehensive. It may, for the reader's convenience, be limited to a single aspect of the topic. Some articles are compendiums which treat several topics together, to show the relationships among them. At Wikipedia, this is called a "portal" article. | An article, as part of an [[encyclopedia]], tells the reader about a topic. It may cover an entire topic - and thus be comprehensive.
