Hi Mark,
> Okay. I did that and when I move the \paper (yes, my bad, I did write \page) into the \bookpart it generates a separate PDF for each \bookpart
Hmmm… It should generate a page break between bookparts, but shouldn’t generate a new PDF!!
The issue is that LilyPond treats \book and \bookpart values in the same
way (no, that's not really wonderful). Basically, when you do this:
x = \bookpart { bla bla }
\x
At the point \x is used, LilyPond has "forgotten" that \x was not a book
but a bookpart, and it treats it as a new book, whereas
\book {
\x
\y
}
forces \x and \y to be treated as bookparts inside one book.
