The three most common scenarios for creating a master document depend on the current state of your document:
- You have one existing document (a book) that you want to split into several subdocuments (chapters) that will be controlled by the master document.
- You have several existing documents (chapters) by one or more authors that you want to combine into one book, controlled by the master document.
- You have no existing documents but intend to write a long book containing several chapters, possibly by multiple authors.
We will look at each of these scenarios in turn.
