Any competent editor/publisher most likely would prefer that you do NO FORMATTING or layout. The usual preference is double-spaced plain text - PERIOD - from authors.

A few years back LiK got a panic call from a friend(?) who had written a rather large book on the History of Alcoholics Anonymous In the US with the information that he'd already contracted with a printer and the book was due "next week."

And - oh, yeah, by the way, "I typed it all in uppercase TO MAKE IT EASIER FOR THE REVIEWERS." He'd also used a very primitive word processor and had inserted line breaks (typewriter style) at the end of every line.

It didn't get all the normal edits/proofs/layout/galley/re-proof quality control, but it made it to the printer and wasn't too bad a book. (As a "friend" he didn't pay us what it was worth, of course; but we were small and could work in a favor then.)

Keep it simple.
