Like listing and clustering, outlining is both a means of inventing what you want to say in an essay and a way of organizing your ideas and information. As you outline, you nearly always see new possibilities in your subject, discovering new ways of dividing or grouping information and seeing where you need additional information to develop your ideas. Because outlining lets you see at a glance where your essay’s strengths and weaknesses lie, outlining can also help you read and revise your essay with a critical eye.
There are two main forms of outlining: informal outlining and formal topic or sentence outlining. Among the several types of informal outlining, scratch outlines are perhaps the most adaptable to a variety of situations. Chunking is another useful method. (Clustering also may be considered a type of informal outlining.)
A scratch outline is little more than a list of the essay’s main points. You have no doubt made scratch outlines many times—to plan essays or essay exams, to revise your own writing, and to analyze a difficult reading passage. Here are sample scratch outlines for two different kinds of essays. The first is an outline of Annie Dillard’s essay in Chapter 2 (pp. 17–19), and the second shows one way to organize a position paper (Chapter 6):
Scratch Outline: Essay about a Remembered Event
Scratch Outline: Essay Arguing a Position
Remember that the items in a scratch outline do not necessarily coincide with paragraphs. Sometimes two or more items may be developed in the same paragraph or one item may be covered in two or more paragraphs.
Chunking, a type of scratch outline commonly used by professional writers in business and industry and especially well suited to writing in the electronic age, consists of a set of headings describing the major points to be covered in the final document. What makes chunking distinctive is that the blocks of text—or “chunks”—under each heading are intended to be roughly the same length and scope. These headings can be discussed and passed around among several writers and editors before writing begins, and different chunks may be written by different authors, simply by typing notes into the space under each heading. The list of headings is subject to change during the writing, and new headings may be added or old ones subdivided or discarded as part of the drafting and editing process.
The advantage of chunking in your own writing is that it breaks the large task of drafting into smaller tasks in a simple, evenly balanced way; once the headings are determined, the writing becomes just a matter of filling in the specifics that go in each chunk. Organization tends to improve as you get a sense of the weight of different parts of the document while filling in the blanks. Places where the essay needs more information or there is a problem with pacing tend to stand out because of the chunking structure, and the headings can be either taken out of the finished essay or left in as devices to help guide readers. If they are left in, they should be edited into parallel grammatical form like the items in a formal topic or sentence outline, as discussed below.
Topic outlines and sentence outlines are considered more formal than scratch outlines because they follow a conventional format of numbered and lettered headings and subheadings:
The difference between a topic and sentence outline is obvious: Topic outlines simply name the topics and subtopics, whereas sentence outlines use complete or abbreviated sentences. To illustrate, here are two partial formal outlines of an essay arguing a position, Jessica Statsky’s “Children Need to Play, Not Compete,” from Chapter 6 (pp. 250–55).
Formal Topic Outline
Formal Sentence Outline
In contrast to an informal outline in which anything goes, a formal outline must follow many conventions. The roman numerals and capital letters are followed by periods. In both topic and sentence outlines, the first word of each item is capitalized, but items in topic outlines do not end with a period as items in sentence outlines do. Every level of a formal outline except the top level (identified by the roman numeral I ) must include at least two items. Items at the same level of indentation in a topic outline should be grammatically parallel—all beginning with the same part of speech. For example, I.A and I.B are parallel when they both begin with an adverb (Physically harmful and Psychologically harmful ) or with an adjective (Harmful physically and Harmful psychologically); they would not be parallel if one began with an adverb (Physically harmful) and the other with an adjective (Harmful psychologically).
