Outlining a textbook chapter is not just copying down the first sentence of every paragraph or every heading headings. A good outline demonstrates understanding of the material and an ability to identify and summarize its main points. If you are outlining for a class assignment, follow any assignment instructions first; some teachers prefer outlines with sentences, while others want outlines with keywords and topics only. If you are outlining for yourself, follow whatever style best fits the purpose of the outline.

For the Vietnam War chapter, you might choose three main headings: Before the War, During the War and After the War.
Step 3
Adhere to the outline format. Outlines typically have several different levels; one of the most common formats has heading titles preceded by I, II, III. Subheadings begin with capital letter headings, followed by Arabic numeral headings (1, 2, 3), followed by lowercase Roman numeral headings (i, ii, iii). Label each level of heading and content with both a number or letter and a title, key word, or sentence, and indent each successive level of headings more than the previous level. Use the structure your instructor prefers, if given.
Step 4
Search for the main ideas and subjects as you re-read the chapter and write your outline. Under each main heading, add subheadings that elaborate on the subject, giving additional facts and details. For the Vietnam War, you might have subheadings with key
