Articles appear in a wide range of publications, including newspapers, magazines, scholarly and professional journals, and Web sites. Articles rely heavily on information obtained from sources such as books, Web sites, government reports, interviews, surveys, and observation. Writers of articles should consider several factors as they plan, draft, design, revise, and edit an article: the audience addressed by their target publication, the subjects typically written about in the publication, the style and tone used by other articles in the publication, and the overall design of the publication.
