Many books feature prefaces that are numbered differently from the rest of the book, usually with lower-case Roman numerals. In such cases, the main body of the book resumes numbering at 1. Word’s simple page numbering scheme makes this impossible. This is the scheme by which you go to the top menu bar, select Insert, select Page Numbers, and select OK; even if you were to select Format in order to have access to more options, none of these permit you to implement two numbering schemes on one document. No, you need to carry out a more complex set of maneuvers in order to pull that off.
To begin, you must divide your text between that with one numbering scheme (lower-case Roman numerals) and another with the more conventional numbering scheme. So you choose to divide your text just before Chapter One.
1-At the top menu bar, select Insert, select Break. You will find a dialog box divided in two sections; one entry in the upper section is already selected. Select instead an entry in the lower section marked Next Page. Through this, the text is divided as intended.
2-Start the numbering of the second section by putting your cursor somewhere in the second section of your text, in the chapters section. Click View from the top menu bar, select Header and Footer
3- You will find a Header and Footer bar. It features Insert Auto Text on the left, a series of icons through it, and Close on the right. The fourth icon to the right is called Same as Previous; place the cursor on it to see the tool tip indicating thus. Click that icon to deselect it. Select Close.
3-Place the cursor in the chapters section. On the top menu bar, click onto Insert, then select Page Numbers…, then Format. Select Start At. Select OK.
4-Place the cursor in the preface section. On the top menu bar, click onto Insert, then select Page Numbers…, then Format. At the top of the dialog box is a Number Format scroll menu. Select the lower Roman numerals format. Again, select Start At. Select OK.
