While writing a research report today, I was stumped as to how to add outline numbering to my heading styles. The resource I used for Word 2003 was not helping much for Word 2007 as the menus have changed. However, it looks like the steps are the same, so here is how to use that guide to set up you outline numbering in Word 2007.

1. Step 1 is the same, set up your heading styles so they cascade (ie Level 2 is based on Level 1).
2. Step 2 is different! In Word 2007, you must “Define a New List style”. To do this, click on the Multilevel List icon from the paragraph section of the Home tab and select “Define a New List style”. Click “Format” and then “Numbering”. You are now in a similar dialog to the “Customize Outline Numbered List” mentioned in the other guide.
   
   
3. Follow the rest of the other guide.
