A Contents page only lists certain types of sections. Industry standards advise a certain order of appearance:
The Table of Contents should only list content that comes after it. Copyright, Dedication, and other content that comes prior is not to be listed.
Listings in your Table of Contents are always listed by order of appearance with front matter content (Foreword, Preface, etc.) emphasized a certain way. To display your information clearly, group your chapters by section:
Many modern text editors have an automatic Table of Contents feature built in to handle content listing.
Your choice of font should remain the same between your Table of Contents, front matter, core matter, and back matter. Instead of using a different font entirely, use text emphasis (Bold, Italics, Underline, and Uppercase Text) and different sizes to separate categories.
Table of Contents text is displayed in full justification with content titles on the left and page numbers on the right. In order to space the content and number properly, use a Right Align Tab (in Microsoft Word) or Right Indent Tab (in Adobe InDesign).
