Thanks again. I've downloaded all your Booth Tarkington books since I've done a few illustrated books myself and am interested in seeing how other people do it. They are rising to the top of my TBR list.

I think it's perfectly acceptable to add material from other editions - most of us make it clear that the ebooks we design are not necessarily based on a particular edition. I try to specify the sources of text and illustrations, and any preface to this edition notes.
