Create a master document and subdocuments

1. Click New Blank Document on the Standard toolbar.
2. On the View menu, click Outline.
3. Type headings for the document title and each subdocument. Make sure to press ENTER after typing each heading.

   Word formats the headings with the built-in heading style Heading 1.

4. Assign a heading style to each heading (for example, use Heading 1 for the title and Heading 2 for each subdocument). To do this, use the buttons on the Outlining toolbar:
   • Click Promote to increase the heading level.
   • Click Demote to decrease the heading level.

1. Open the document that you want to use as your master document.
2. On the View menu, click Outline.
3. Assign a heading style to each heading (for example, use Heading 1 for the title and Heading 2 for each subdocument). To do this, use the buttons on the Outlining toolbar:
   • Click Promote to increase the heading level.
   • Click Demote to decrease the heading level.
4. As necessary, for any content that is not a heading, select the content and click Demote to Body Text on the Outlining toolbar.

You must have a master document outline to create a subdocument from an outline heading.

1. On the View menu, click Outline.
2. In the master document, select the headings and text you want to separate into subdocuments.

   Make sure that the first heading in the selection is formatted with the heading style or outline level you want to use for the beginning of each subdocument. For example, if the selection begins with Heading 2, Word creates a new subdocument at each Heading 2 in the selected text.

3. On the Outlining toolbar, click Create Subdocument .

Word inserts a continuous section break before and after each subdocument.

Notes

• If the Create Subdocument button isn't available, you need to first click Expand Subdocuments .

• After you add a subdocument to a master document, do not move or delete it unless you first remove it from the master document.
• Rename a subdocument only from within the master document.

1. Open the master document and click Outline on the View menu.
2. If the subdocuments are collapsed, click Expand Subdocuments on the Outlining toolbar.
3. Click where you want to add the existing document.

   Make sure to click a blank line between existing subdocuments.

4. On the Outlining toolbar, click Insert Subdocument .
5. In the File name box, enter the name of the document you want to add, and then click Open.

Microsoft Word inserts a next page section break before the subdocument and a continuous section break after it.
