General notes on large documents and combining documents.
- Combining documents is probably easiest if they are based on the same template.
- If possible, all formatting should be done using styles. Direct formatting exponentially increases document complexity and makes editing much harder. With short documents this isn't a big problem, with long ones it is.
- Hard page breaks should be avoided. Use paragraph formatting of page break before where a page break has to be forced.
- Never, ever, use the Master Documents Feature in Microsoft Word - at least not until you read the articles at this link.
- If you use automatic paragraph numbering read Shauna Kelly's articles on numbering and bullets.
