For documents smaller than a book, such as journal articles, white papers, or technical notes, article is frequently the most logical starting point. The body of an article is essentially the same as the body of a chapter or any other component-level element, as shown in Example 2-3.

articles may include appendixes, bibliographys, indexes, and glossarys.
