From within your master document, you can create tables of contents and indexes that reflect the contents of all your subdocuments. Follow these steps:
Open the master document, display it in Outline view, and click the Master Document View toolbar button.
Click Expand Subdocuments to make the contents of all subdocuments visible.
Position your insertion point where you want to create your table of contents, index, or cross-reference.
Follow Word's procedures for inserting an index, a table of contents, or cross-references. You can work from the Insert, Reference, Index and Tables dialog box or the Insert, Reference, Cross-Reference dialog box; or insert index fields directly by pressing Alt+Shift+X and working from the Mark Index Entry dialog box; or enter fields directly by pressing Ctrl+F9 and editing the text between the field brackets.
For more information on creating tables of contents, see "Quick and Easy Tables of Contents," p. 682.
For more information on creating indexes, see "Creating a New Index Entry," p. 716, and "Compiling Your Index," p. 724.
For more information on building and using cross-references, see "Working with Cross-References," p. 758.
You can enter your fields in the master document, in a subdocument displayed in the master document, or in a subdocument displayed in its own editing window.
If you open a subdocument using File, Open rather than opening it from within the master document, any table of contents, index, or cross-reference you create won't reflect the contents of the master document.
After you have created a table of contents in a master document, you can work with it using the Go To TOC and Update TOC buttons on Word's Master Document toolbar.
If you click the Go to TOC button, Word selects your document's table of contents. If you click the Update TOC button, Word updates your table of contents, allowing you to choose whether you want to update only page numbers or the entire table of contents including the text of each listing.
