Thanks for the tip.
When I saved the epub with that <hr> tag, it didn't split that file. Is this part of a larger series of steps? I guess what I was really looking for, was the answer to the "single page break definition" I've heard an epub can have, that is separate from a chapter break/new file. That is, a Page Break, in word processor terminology. Does this do anything along that line or is it completely different?
