I'm sorry. I wasn't reading your post as carefully as I should have. Thanks for getting back on this. That section referring to the printing history statement specifically says that it goes on the supplemental title page. There is no provision for placing it on the main title page and I agree, there would never be room for it. So yes, whevnever you have a printing history given, the actual history numbers go on the main title page right after the ISBN and the printing history statement goes on the supplemental title page, even if that's the only item on it. The printing history statement is given only in Volume 1.
