Just a mild recap: unless there is a strong reason to break the book into chapters and use the Book feature, you will probably find it easier to work with as a single document.
The only good arguments for using Book structure are:
- If component chapters need to be edited and developed individually, by timeline or author/editor.
- If the chapters are very large files, meaning a single-file doc would be very very large and unwieldy.
- If you may need to create variant editions that incorporate some subset of a library of chapters.
But for your basic nonfic book of reasonable size — up to 500-600 pages, without more than a few dozen images — putting it in Book structure just adds a rather cranky layer of project management without bringing much value.
Thanks. The pros for me on using an INDB file, and INDD files, is that I can easily move chapters around; and the chapter documents are not as unwieldly. Having said that, the next book I may try both approaches and see which I like better. Thanks for the input.
