I had separate word docs for each chapter, and got Acrobat to combine them that way. I'd tried having doc files of the story in the past, but if I put more than a few chapters in a file it'd seize up on me.

I wasn't being snappy, by the way. If you do figure out a way to make it smaller, go for it. I know it's likely possible; it's just text after all, with nothing more fancy than bold and italic.
