A follow up after some thought. From working with publishing software (this was years ago, but I'm pretty sure the same concept still rules) the actual text of books lies in textboxes that are positioned on the master pages, flowing from one column to the next. The text itself (especially that of the main "story", which is a continual text box flowing from page to page) is separate from the background, images, or layout and could be saved in a text-only format. However, the biggest problem I would see would be the many tables. They are definitely not ebook friendly, and would have to be skipped or converted into images (skipping would reduce value, converting into images would take time and effort).
Then again, I own the pathfinder book and I'm not looking for something to replace it, but more to supplement it so I can read through the pathfinder manual away from home (since it's huge and heavy) and search through it at gametime. PDFs for now it is.
