Your selections in the Options section will determine how PageMaker will handle a document that has multiple pages.
Single-sided
Select this option by un-checking the Double-sided box. The single-sided option creates a publication that will print on only one side of each page. Only one master page will be created.
Double-sided
Select this option for a publication that will print on both sides of each page. The pages will still be displayed one at a time on your screen. However, two master pages will be created.
Facing Pages
Select this option to display two pages at a time on your screen (all except page 1, which is typically displayed alone). This is the appropriate option if you are working on a booklet or magazine, which will have their pages set up to face each other, much like a book's. You cannot have facing pages unless they are double sided.
