The process of setting up chapter and volume numbers is essentially the same as setting up page numbers. You can use these numbering elements as a way to keep track of any number of items. Yes, they are labeled “chapters” and “volumes,” but if you ignore the labels, you’ll see that you can keep track of any “section” in a document. In fact, if you count page numbers, chapter numbers, volume numbers, and secondary page numbers, you’ll see that you have four different numbering methods at your disposal.
The easiest way to implement a numbering scheme for headings is to add one to a heading style. To illustrate, we'll modify Heading 1 by adding a numbering scheme. First, right-click Heading 1 in the Styles gallery (in the Styles group on the Home tab). Then, choose Modify as shown in Figure A to launch the Modify Style dialog. If you thumb through the default properties, you'll not find a numbering scheme (Figure B). Click the Format button and choose Numbering as shown in Figure B. If necessary, click the Numbering tab. Choose the predefined scheme that's the best match for what you want (Figure C). document numbering in word
