I have created a long document (in Word 2010) that includes headings and 2 sections. The first section is a table of contents and the 2nd section of 200 pages is the body of the document. I have created a separate title document consisting of simply the title and a single piece of clip art.
How do I add this title document to the beginning of the main one using its own formatting, but not changing the formatting of the main doc? I want to have a single document to give to the printer.
Thanks, John

Put a new-page section break at the end of your introductory material. Copy everything in that document including that section break to the beginning of your long document.

You may need to make some adjustments such as headers/footers in your TOC section.

For more information, see: Numbering Front Matter (Ribbon), and Sections / Headers and Footers in Microsoft Word (Ribbon Versions).

Note, also, that what you get back from the printer may be different from what you expect. Word formats documents according to the printer. What happens when I send my document to someone else? Will Word mess up my formatting?

You may want to convert to a pdf and send that to the printer. If you do that, you could probably just combine the pdfs from your parts into one file.
