What is an Outline?

An outline is useful because it allows you to assign information to a hierarchy so that you can write a coherent paper. A hierarchy, or hierarchic structure, is a way of classifying information from major to minor, or most important to least important. A major point is supported by minor points. Minor points are supported by evidence. Don’t mistake “least important” for “unimportant.” All information in your paper should be important, or it shouldn’t be included.
