Your guidance is very helpful. Thank you for being so patient. I see that I should work in "headers". In the test copy I created I actually got it all to work. But when I re-opened it, it had reverted. I carefully went through each section verifying that I had "different first page" and both "odd / right" and "even / left" headers. I had also set the document formaatting that way. I see now, too, that all the formatting is within the section, guided by the section break at the end of the section. So I think I'm making progress. I am going to abandon this problem for the moment and update everything else (index, glossary, notes, etc.) and then come back to this. I fear, too, that one problem is the instability of the Mac version of Word (something everybody complains about). It may be why I can get everything "right" and think I've licked the problem, only to find it return when I reopen the document. Too frustrating...

Taking a few deep breaths for a while, and working on other stuff. See you later (smile!), and thank you, again,
