In each page layout, you need to decide how many pages you need and add them to the layout. The number of pages that you add depends on the differences that may occur on the various pages. For example, you might add a First Right page to be used only for the first page of the chapter. You also might add a Left page for even pages (e.g., 12, 14, 16, 18) and a Right page for odd pages (e.g., 11, 13, 15, 17). Each of those page types might display header or footer content differently. You also might want to add an Empty Left page to make sure that new chapters start on a right page. In the Page Layout Editor, only one page will be visible at any one time, but you can navigate to the other pages quickly by using the small squares to the right of the editor (one for each page in the page layout).
Using the Page Properties drop-down button 
in the local toolbar of the Page Layout Editor, you can add a new page to a layout in any of the following ways:
- Duplicate or Copy a Page Use one of these methods if you have already created and configured a page and want the new page to share some of the same settings. After the new page is created (which is exactly like the original page, except for the page name), you can change any of the frame content or other settings as needed. The only difference between the duplicate and copy method is that duplicating a page requires one less step.
- Insert a Page Use this method if you want to add a new page that initially is completely blank. After inserting a page, it takes on the size and margins of the previous page in the layout. However, you must add frames, content, and other settings to the new page as needed (unless you want to use it as a completely blank "empty page").
-
Mirror a Page Use this method if you have already created and configured a page and want the new page to share the same settings, with the page setup "mirrored" (i.e., the left and right margin settings will be reversed). For example, if the left margin on the original page is 1.5 inches and the right margin is .75 inches, the mirrored page will have a left margin of .75 inches and a right margin of 1.5 inches. This feature is typically used if you plan to create a Left page (for even pages) and a Right page (for odd pages). Most of the time, you would want a greater margin on the side of the page closest to any binding (to compensate for the extra space consumed by the binding).
Note If you have created mirror margins on your pages and are compiling Microsoft Word output, you need to enable the mirror margins in the Target Editor. See Enabling Mirror Margins in Word Output.
