(I never include the scripture references in an audiobook anyway as I think it ruins the flow of the text. I figure the listeners can look it up if they really want to, and most of them will know the references anyway.)
But the Kindle "bundle" of six books doesn't seem to have extra scripture references, so if you text-check against that one you should be OK. It's also available in a variety of formats which will suit most people, I think. (Just not great for me, on a Mac, but I'll cope if necessary.)
I'm not sure how much text you would need to check to be sure - not the whole book, presumably. Maybe just the last 2 pages of each chapter? That's where things are most likely to be inadvertently chopped off, I guess.
Here's the link for the Kindle bundle again:
Or this is the "Six Kindle books" collection - if this one matched, would we be able to argue that all of them would be usable? All these books were published in the 1800's, so there's no issue with the original copyrights.
